4Withdraw the pads from the caliper piston
housing or anchor bracket. The outer pad will
normally remain in position in the anchor
bracket, but the inner pad will stay attached to
the piston in the caliper, and may need to be
carefully prised free. If the old pads are to be
refitted, ensure that they are identified so that
they can be returned to their original
positions.
5 Brush the dust and dirt from the caliper and
piston, but do not inhale it, as it is a health
hazard . Inspect the dust cover around the
piston for damage and for evidence of fluid
leaks, which if found will necessitate caliper
overhaul as described in Section 3.
6 If new brake pads are to be fitted, the
caliper piston will need to be pushed back
into its housing, to allow for the extra pad
thickness - use a C-clamp to do this. Note
that, as the piston is pressed back into the
bore, it will displace the fluid in the system,
causing the fluid level in the brake master
cylinder reservoir to rise and possibly
overflow. To avoid this possibility, a small
quantity of fluid should be removed from the
reservoir. If any brake fluid is spilt onto the
bodywork, hoses or adjacent components in
the engine compartment, wipe it clean without
delay.
7 Prior to refitting, check that the pads and
the disc are clean. Where new pads are to be
installed, peel the protective backing paper
from them. If the old pads are to be refitted,
ensure that they are correctly located as
noted during their removal.
8 Locate the inner and outer brake pad into
position in the caliper. Relocate the caliper
into position on the anchor bracket, and insert
the mounting bolts.
9 Tighten the mounting bolts to the specified
torque, and refit the blanking plugs. Relocate
the caliper support spring.
10 Repeat the procedure on the opposite
front brake. 11
Before lowering the vehicle, check that
the fluid level in the brake master cylinder
reservoir is up to the “Maximum level” mark,
and top-up with the specified fluid type if
required (see “Weekly Checks” ). Depress the
brake pedal a few times to position the pads
against the disc, then recheck the fluid level in
the reservoir and further top-up if necessary.
12 Refit the roadwheels, then lower the
vehicle to the ground. Tighten the roadwheel
retaining nuts to the specified torque.
13 To allow the new brake pads to bed-in
and reach full efficiency, a running-in period of
approximately 100 miles or so should be
observed before hard use and heavy braking.
3 Front brake caliper - removal,
overhaul and refitting
4
Note: Before starting work, refer to the
warning at the beginning of Section 13
concerning the dangers of hydraulic fluid, and
to the warning at the beginning of Section 2
concerning the dangers of asbestos dust.
Removal
1 Chock the rear wheels then jack up the
front of the car and support it on axle stands
(see “Jacking and Vehicle Support” ). Remove
the front roadwheels.
2 Fit a brake hose clamp to the flexible brake
hose leading to the front brake caliper. This
will minimise brake fluid loss during
subsequent operations.
3 Loosen by half a turn, the union on the
caliper end of the flexible brake hose.
4 Remove the front brake pads as described
in Section 2.
5 Support the caliper in one hand, and
prevent the brake hose from turning with a
spanner in the other hand. Unscrew the
caliper from the hose, making sure that the
hose is not twisted unduly or strained (see
illustration) . Once the caliper is detached,
cover or plug the open hydraulic unions to
keep them clean.
6 If required, the caliper anchor bracket can
be unbolted and removed from the spindle
carrier (see illustration) .
Overhaul
7With the caliper on the bench, wipe away all
traces of dust and dirt, but avoid inhaling the
dust, as it is a health hazard .
8 Remove the piston from its bore by
applying low air pressure (from a foot pump,
for example) into the caliper hydraulic fluid
hose port. In the event of a high-pressure air
hose being used, keep the pressure as low as
possible, to enable the piston to be extracted,
but to avoid the piston being ejected too
quickly and being damaged. Position a
suitable piece of wood between the caliper
frame and the piston to prevent this
possibility. Any fluid remaining in the caliper
will probably be ejected with the piston.
9 Using a suitable hooked tool, carefully extract
the dust cover from its groove in the piston
and the seal from its groove in the caliper bore,
but take care not to scratch or damage the
piston and/or the bore in the caliper.
10 Clean all the parts in methylated spirit or
clean brake fluid, and wipe dry using a clean
lint-free cloth (see illustration) . Inspect the
piston and caliper bore for signs of damage,
scuffing or corrosion. If these conditions are
evident, renew the caliper body assembly.
11 If the components are in satisfactory
condition, a repair kit which includes a new
seal and dust cover must be obtained.
12 Lubricate the piston bore in the caliper
and the seal with clean brake fluid. Carefully
fit the seal in the caliper bore, using fingers
only (no tools) to manipulate it into position in
its groove. When in position, check that it is
not distorted or twisted.
13 Locate the dust cover over the piston so
that its inner diameter is engaged in the piston
groove. Smear the area behind the piston
groove with the special lubricating grease
supplied in the repair kit, then insert the piston
into the caliper. Push the piston into position in
the bore, and simultaneously press the dust
cover into the piston housing so that it is seated
correctly. Take particular care not to distort or
damage the seal or cover as they are fitted.
Refitting
14 If the anchor bracket was removed, fit it
into position on the spindle carrier, and tighten
the retaining bolts to the specified torque.

13 Hydraulic system- bleeding
(conventional braking system)
3
Note: For vehicles equipped with an anti-lock
braking system, refer to Section 14. Warning: Hydraulic fluid is
poisonous; wash off
immediately and thoroughly in
the case of skin contact, and
seek immediate medical advice if any fluid
is swallowed or gets into the eyes. Certain
types of hydraulic fluid are inflammable,
and may ignite when allowed into contact
with hot components; when servicing any
hydraulic system, it is safest to assume
that the fluid IS inflammable, and to take
precautions against the risk of fire as
though it is petrol that is being handled.
Hydraulic fluid is also an effective paint
stripper, and will attack plastics; if any is
spilt, it should be washed off immediately,
using copious quantities of clean water.
Finally, it is hygroscopic (it absorbs
moisture from the air). The more moisture
is absorbed by the fluid, the lower its
boiling point becomes, leading to a
dangerous loss of braking under hard use.
Old fluid may be contaminated and unfit
for further use. When topping-up or
renewing the fluid, always use the
recommended type, and ensure that it
comes from a freshly-opened sealed
container.
1 The correct operation of any hydraulic
system is only possible after removing all air
from the components and circuit; and this is
achieved by bleeding the system.
2 During the bleeding procedure, add only
clean, unused hydraulic fluid of the
recommended type; never re-use fluid that
has already been bled from the system.
Ensure that sufficient fluid is available before
starting work.
3 If there is any possibility of incorrect fluid
being already in the system, the brake
components and circuit must be flushed
completely with uncontaminated, correct
fluid, and new seals should be fitted
throughout the system.
4 If hydraulic fluid has been lost from the
system, or air has entered because of a leak,
ensure that the fault is cured before
proceeding further.
5 Park the vehicle on level ground, and apply
the handbrake. Switch off the engine, then
(where applicable) depress the brake pedal
several times to dissipate the vacuum from
the servo unit. Note:When bleeding the
system, the vehicle must maintain a level
attitude, ie not tilted in any manner, to ensure
that air is not trapped within the pressure
control valves. During certain operations in
this manual, instructions are given to bleed the
brake hydraulic system with the front or the
rear of the vehicle raised. In such cases raise
the rest of the vehicle so that it maintains a level attitude, but only if it is safe to do so. If it
is not possible to achieve this safely, complete
the remainder of the operation and bleed the
brake hydraulic system with the vehicle on its
wheels.
6
Check that all pipes and hoses are secure,
unions tight and bleed screws closed.
Remove the dust caps (where applicable), and
clean any dirt from around the bleed screws.
7 Disconnect the wiring multi-plug from the
fluid level warning indicator in the master
cylinder reservoir filler cap, then remove the
filler cap. Note that the filler cap must not be
inverted. Top-up the reservoir with the
specified fluid to the “Maximum” level (see
“Weekly Checks” ). Remember to maintain the
fluid level at least above the “Minimum” level
line throughout the procedure, otherwise
there is a risk of further air entering the
system.
8 There are a number of one-man, do-it-
yourself brake bleeding kits currently available
from motor accessory shops. It is
recommended that one of these kits is used
whenever possible, as they greatly simplify
the bleeding operation, and also reduce the
risk of expelled air and fluid being drawn back
into the system. If such a kit is not available,
the basic (two-man) method must be used,
which is described in detail below.
9 If a kit is to be used, prepare the vehicle as
described previously, and follow the kit
manufacturer’s instructions, as the procedure
may vary slightly according to the type being
used; generally, they are as outlined below in
the relevant sub-section.
10 Whichever method is used, the same
sequence must be followed (paragraphs 11
and 12) to ensure the removal of all air from
the system.
Bleeding sequence
11 If the system has been only partially
disconnected, and suitable precautions were
taken to minimise fluid loss, it should be
necessary to bleed only that part of the
system (ie the primary or secondary circuit).
12 If the complete system is to be bled, then
it is suggested that you work in the following
sequence: a) Right-hand front wheel.
b) Left-hand rear wheel.
c) Left-hand front wheel.
d) Right-hand rear wheel.
Bleeding - basic (two-man)
method
13 Collect a clean glass jar, a suitable length
of plastic or rubber tubing which is a tight fit
over the bleed screw, and a ring spanner to fit
the screw. The help of an assistant will also be
required.
14 Remove the dust cap from the first screw
in the sequence (if not already done). Fit a
suitable spanner and tube to the screw, place
the other end of the tube in the jar, and pour in
sufficient fluid to cover the end of the tube.
15 Ensure that the master cylinder reservoir fluid level is maintained at least above the
“Minimum” level throughout the procedure.
16
Have the assistant fully depress the brake
pedal several times to build up pressure, then
maintain it down on the final downstroke.
17 While pedal pressure is maintained,
unscrew the bleed screw (approximately one
turn) and allow the compressed fluid and air to
flow into the jar. The assistant should maintain
pedal pressure, following the pedal down to
the floor if necessary, and should not
release the pedal until instructed to do so.
When the flow stops, tighten the bleed screw
again. Have the assistant release the pedal
slowly, and recheck the reservoir fluid level.
18 Repeat the steps given in paragraphs 16
and 17 until the fluid emerging from the bleed
screw is free from air bubbles. If the master
cylinder has been drained and refilled, and air
is being bled from the first screw in the
sequence, allow at least five seconds between
cycles for the master cylinder passages to refill.
19 When no more air bubbles appear, tighten
the bleed screw securely, remove the tube
and spanner, and refit the dust cap (where
applicable). Do not overtighten the bleed
screw.
20 Repeat the procedure on the remaining
screws in the sequence, until all air is
removed from the system and the brake pedal
feels firm again.
Bleeding - using a one-way
valve kit
21 As their name implies, these kits consist of
a length of tubing with a one-way valve fitted,
to prevent expelled air and fluid being drawn
back into the system; some kits include a
translucent container, which can be positioned
so that the air bubbles can be more easily
seen flowing from the end of the tube.
22 The kit is connected to the bleed screw,
which is then opened (see illustration). The
user returns to the driver’s seat, depresses
the brake pedal with a smooth, steady stroke,
and slowly releases it; this is repeated until
the expelled fluid is clear of air bubbles.
23 Note that these kits simplify work so
much that it is easy to forget the master
cylinder reservoir fluid level; ensure that this is
maintained at least above the “Minimum” level
at all times.

Bleeding - using a pressure-
bleeding kit
24These kits are usually operated by the
reservoir of pressurised air contained in the
spare tyre. However, note that it will probably
be necessary to reduce the pressure to a
lower level than normal; refer to the
instructions supplied with the kit.
25 By connecting a pressurised, fluid-filled
container to the master cylinder reservoir,
bleeding can be carried out simply by opening
each screw in turn (in the specified sequence),
and allowing the fluid to flow out until no more
air bubbles can be seen in the expelled fluid.
26 This method has the advantage that the
large reservoir of fluid provides an additional
safeguard against air being drawn into the
system during bleeding.
27 Pressure-bleeding is particularly effective
when bleeding “difficult” systems, or when
bleeding the complete system at the time of
routine fluid renewal.
All methods
28 When bleeding is complete, and firm
pedal feel is restored, wash off any spilt fluid,
tighten the bleed screws securely, and refit
their dust caps.
29 Check the hydraulic fluid level in the
master cylinder reservoir, and top-up if
necessary.
30 Discard any hydraulic fluid that has been
bled from the system; it will not be fit for re-
use.
31 Check the feel of the brake pedal. If it
feels at all spongy, air must still be present in
the system, and further bleeding is required.
Failure to bleed satisfactorily after a
reasonable repetition of the bleeding
procedure may be due to worn master
cylinder seals.
14 Hydraulic system - bleeding
(anti-lock braking system)
3
Note: Before starting work, refer to the
warning at the beginning of Section 13
concerning the dangers of hydraulic fluid.
1 On vehicles equipped with the anti-lock braking system there are two bleed
procedures possible, depending on which
part of the brake hydraulic system has been
disturbed.
2
If any one of the following conditions are
present, bleed procedure A should be
adopted: a) A modulator has been removed.
b) A modulator return hose (between
modulator and brake fluid reservoir) has
been drained.
c) The rigid brake pipes have been disconnected from a modulator.
3 If any one of the following conditions are
present, bleed procedure B should be
adopted: a) Any condition where the master cylinder
has been removed or drained, providing
that the modulator return hoses have not
lost their head of fluid.
b) Removal or disconnection of any of the
basic braking system components ie,
brake caliper, flexible hose or rigid pipe,
wheel cylinder, or load-apportioning
valve.
Bleed procedure A
4Raise the vehicle on ramps, or drive it over
an inspection pit, so that working clearance
may be obtained with the full weight of the
vehicle on its roadwheels. Remove the one-
piece undertray, as applicable, by turning its
bayonet-type fasteners and, on XR2i models,
remove the front suspension crossmember
(see Chapter 10).
5 Disconnect the wiring multi-plug from the
fluid level warning indicator in the master
cylinder reservoir filler cap, then remove the
filler cap. Note that the filler cap must not be
inverted. Top-up the brake fluid reservoir to
the MAX mark using fresh fluid of the
specified type (see “Weekly Checks”), and
keep it topped up throughout the bleeding
procedure.
6 Slacken the modulator bypass valve Torx
screw, located between the two rigid brake
pipe connections on the modulator body, and
unscrew it two full turns (see illustration).
7 Fully depress the auto-bleed plunger on the
modulator and hold it down so that the
plunger circlip contacts the modulator body
(see illustration) . With the plunger depressed, have an assistant steadily pump
the brake pedal at least twenty times whilst
you observe the fluid returning to the brake
fluid reservoir. Continue this operation until
the returning fluid is free from air bubbles.
8
Release the auto-bleed plunger, ensuring
that it returns to its normal operational
position - pull it out by hand if necessary.
9 Tighten the modulator bypass valve Torx
screw.
10 Repeat the operation on the other
modulator, if applicable, then refit the one-
piece undertray and the front suspension
crossmember if removed.
11 Now carry out bleed procedure B.
Bleed procedure B
12This procedure is the same as for
conventional braking systems, and reference
should be made to Section 13. Note,
however, that all the weight of the vehicle
must be on the roadwheels, otherwise the
load-apportioning valves will not bleed. If
problems are encountered whereby the rear
brakes will not bleed satisfactorily, ensure that
the load-apportioning valves are correctly
adjusted (see Section 25). As with the
conventional braking system, the brake fluid
level must be kept topped up during bleeding.
15 Vacuum servo unit - testing,
removal and refitting
3
Testing
1 To test the operation of the servo, depress
the footbrake four or five times to exhaust the
vacuum, then start the engine while keeping
the footbrake depressed. As the engine starts,
there should be a noticeable “give” in the
brake pedal as vacuum builds up. Allow the
engine to run for at least two minutes, and
then switch it off. If the brake pedal is
depressed again, it should be possible to
detect a hiss from the servo when the pedal is
depressed. After about four or five
applications, no further hissing will be heard,
and the pedal will feel considerably firmer.
2 Before assuming that a problem exists in
the servo itself, check the non-return valve as
described in the next Section.
Removal
3 Refer to Section 9 and remove the master
cylinder.
4 Disconnect the vacuum hose at the servo
non-return valve by pulling it free. If it is
reluctant to move, assist it by prising it free
using a screwdriver with its blade inserted
under the elbow flange.
5 Lift up the flap of sound insulation on the
bulkhead, in the passenger side footwell, to
expose the servo mounting bracket retaining
nuts (see illustration 11.6) . Remove the two
innermost nuts to free the inner section of the
servo mounting bracket from its bulkhead

4Chock the rear wheels then jack up the
front of the car and support it on axle stands
(see “Jacking and Vehicle Support” ).
5 Remove the one-piece undertray where
fitted, by turning the bayonet type fasteners,
and on XR2i models, remove the front
suspension crossmember (see Chapter 10).
6 From underneath, remove the belt-break
switch from the right-hand drivebelt cover by
squeezing its release lever towards the main
body of the switch (see illustration), then
carefully withdraw, ensuring that the belt
contact arm does not catch on the drivebelt
cover.
7 Remove the two bolts securing the
modulator drivebelt cover to the modulator
mounting bracket, and withdraw the cover
(see illustration) .
8 Disconnect the rigid brake pipes from the
modulator, fitting blanking plugs to prevent
excessive fluid loss and dirt ingress.
9 Remove the modulator pivot bolt and
adjuster bolt (see illustration) , then slip the
drivebelt from its pulley, and withdraw the
modulator unit from the vehicle. Ensure that
the modulator return hose does not become
kinked as the modulator unit is withdrawn.
10 Disconnect the modulator return hose
from the modulator unit, and fit a blanking
plug to prevent dirt ingress. Allow for residual
fluid spillage as the hose is disconnected.
11 If a new modulator is to be fitted, note that
these units are not interchangeable from side
to side, and the correct replacement must be
obtained. The modulator units are colour-
coded, and must be fitted with the arrows on
top of the casings pointing towards the front
of the vehicle.
12 To refit, first connect the modulator return
hose to the return outlet on the modulator
unit.
13 Locate the modulator unit to its bracket
and fit the pivot bolt, having applied a thin
smear of anti-seize compound to the bolt, but
do not fully tighten at this stage. Take care not
to damage the modulator return hose as it is
manoeuvred into position.
14 Fit the drivebelt to its modulator pulley
location, ensuring that it sits correctly over the driveshaft pulley, then refit the adjuster bolt
but do not fully tighten at this stage.
15
Adjust the tension of the drivebelt by
moving the modulator unit, until a belt
deflection of 5.0 mm is obtained under firm
finger pressure. Check this using a ruler at a
point midway between the two pulleys.
16 With the drivebelt tensioned correctly,
tighten the pivot and adjuster bolts to the
specified torque. Re-check the tension of the
drivebelt after tightening the bolts.
17 Reconnect the rigid brake pipes to the
modulator, tightening the unions securely.
18 Refit the modulator drivebelt cover to the
modulator mounting bracket, and secure with
its two retaining bolts.
19 Refit the belt-break switch to the
modulator drivebelt cover, taking care not to
damage the belt contact arm as it passes
through the cover.
20 Reconnect the modulator return hose by
pushing the hose firmly into its brake fluid
reservoir location, then lever out the collar to
retain it.
21 Refit the front suspension crossmember
and the one-piece undertray, as applicable.
22 Lower the vehicle to the ground.
23 Top-up the brake fluid reservoir using
fresh fluid of the specified type (see “ Weekly
checks ”), then bleed the brake hydraulic
system in accordance with Section 14. Refit
the reservoir filler cap and warning indicator
wiring multi-plug on completion.
24 Reconnect the battery negative lead.
Left-hand side
25Repeat the procedures given in
paragraphs 1 to 3.
26 Chock the rear wheels then jack up the
front of the car and support it on axle stands
(see “Jacking and Vehicle Support” ). Remove
the front roadwheels.
27 Remove the one-piece undertray where
fitted, by turning the bayonet type fasteners,
and on XR2i models, remove the front
suspension crossmember (see Chapter 10).
28 Remove the belt-break switch from the
left-hand drivebelt cover in a similar manner to
that described in paragraph 6, this time from
the engine compartment. 29
Remove the two bolts securing the
modulator drivebelt cover to the modulator
mounting bracket, then ease the lower portion
of the cover over the driveshaft taking care
not to damage the driveshaft CV joint gaiter.
Withdraw the cover through the engine
compartment, manoeuvring it to clear
obstructions.
30 Disconnect the rigid brake pipes from the
modulator, fitting blanking plugs to prevent
excessive fluid loss and dirt ingress.
31 Slacken the modulator pivot and adjuster
bolts, then swing the modulator downwards
to release the drivebelt tension before slipping
the drivebelt from its modulator pulley
location.
32 Remove the modulator pivot and adjuster
bolts, withdraw the modulator upwards
through the engine compartment. Ensure that
the modulator return hose does not become
kinked as the modulator unit is withdrawn.
33 Disconnect the modulator return hose
from the modulator unit, and fit a blanking
plug to prevent dirt ingress. Allow for residual
fluid spillage as the hose is disconnected.
34 If a new modulator is to be fitted, note that
these units are not interchangeable from side
to side, and the correct replacement must be
obtained. The modulator units are colour-
coded, and must be fitted with the arrows on
top of the casings pointing towards the front
of the vehicle.
35 To refit, first connect the modulator return
hose to the return outlet on the modulator
unit.
36 Locate the modulator unit to its mounting
bracket and fit the pivot bolt, having applied a
thin smear of anti-seize compound to the bolt,
but do not fully tighten at this stage. Take care
not to damage the modulator return hose as it
is manoeuvred into position.
37 Fit the drivebelt to its modulator pulley
location, ensuring that it sits correctly over the
driveshaft pulley, then refit the adjuster bolt
but do not fully tighten at this stage.
38 Adjust the tension of the drivebelt by
moving the modulator unit, until a belt
deflection of 5.0 mm is obtained under firm
finger pressure. Check this using a ruler at a
point midway between the two pulleys.

39With the drivebelt tensioned correctly,
tighten the pivot and adjuster bolts to the
specified torque. Re-check the tension of the
drivebelt after tightening the bolts.
40 Reconnect the rigid brake pipes to the
modulator, tightening the unions to seal the
system.
41 Refit the modulator drivebelt cover and
secure with its two retaining bolts. Take care
not to damage the driveshaft CV joint gaiter as
the cover is eased into position.
42 Refit the belt-break switch to the
modulator drivebelt cover, taking care not to
damage the belt contact arm as it passes
through the cover.
43 Reconnect the modulator return hose by
pushing the hose firmly into its brake fluid
reservoir location, then lever out the collar to
retain it.
44 Refit the front suspension crossmember
and the one-piece undertray, as applicable.
45 Refit the roadwheels, then remove the
axle stands and lower the vehicle to the
ground. Tighten the wheel nuts to the
specified torque.
46 Top-up the brake fluid reservoir using
fresh fluid of the specified type (see “ Weekly
checks ”), then bleed the brake hydraulic
system in accordance with Section 14. Refit
the reservoir filler cap and the warning
indicator wiring multi-plug on completion.
47 Reconnect the battery negative lead.
Modulator drivebelt
48Disconnect the battery negative (earth)
lead (refer to Chapter 5A, Section 1).
49 Chock the rear wheels then jack up the
front of the car and support it on axle stands
(see “Jacking and Vehicle Support” ). Remove
the relevant front roadwheel.
50 Remove the one-piece undertray where
fitted, by turning its bayonet-type fasteners,
and on XR2i models, remove the front
suspension crossmember (see Chapter 10).
51 Remove the belt-break switch from the
relevant drivebelt cover, then remove the
drivebelt cover, as described in the previous
sub-Section.
52 Slacken the modulator pivot and adjuster
bolts to release drivebelt tension, then slip the
drivebelt from the modulator.
53 Remove the track rod end balljoint from
the steering arm on the spindle carrier (see
Chapter 10).
54 Disconnect the anti-roll bar connecting
link (where applicable) and release the brake
hose from their locations on the suspension
strut.
55 Remove the pinch bolt and nut securing
the lower suspension arm balljoint to the
spindle carrier, and separate the balljoint from
the spindle carrier assembly.
56 To release the driveshaft inner CV joint
from the differential, have an assistant pull the
spindle carrier away from the centre of the
vehicle whilst you insert a lever between the
inner CV joint and the transmission casing,
then firmly strike the lever with the flat of the hand, but be careful not to damage adjacent
components. Make provision for escaping
transmission oil, if possible plugging the
opening to prevent excessive loss. Do not
allow the CV joints to bend more than 20°
from the horizontal or internal damage may
occur. If both driveshafts are to be removed,
immobilise the differential by inserting an old
joint or suitable shaft, before the other
driveshaft is removed.
57
Slide the drivebelt off the driveshaft.
58 Remove the snap-ring from the groove in
the splines of the inner CV joint. This snap-
ring must be renewed every time the
driveshaft is withdrawn from the differential.
59 With the drivebelt removed, closely
examine the condition of the belt over its
entire length. Renew the belt if any cracks are
noticed in the fabric at the roots of the teeth, if
there is any abrasion of the fabric facing
material, or if there are any tears starting from
the edge of the belt.
60 If, since the drivebelts were last renewed,
a vehicle has covered more than 30 000 miles
(48 000 km) or a period of more than two
years has elapsed, the drivebelts should be
renewed as a matter of course.
61 Prior to refitting the drivebelt, thoroughly
clean its CV joint pulley location.
62 Fit the drivebelt over the driveshaft then,
with a new snap-ring fitted to the inner CV
joint splines, lubricate the splines with
transmission oil. Remove the temporary plug
and insert the inner CV joint to its
transmission casing location. Press against
the spindle carrier so that the snap-ring
engages fully to hold the CV joint splines in
the differential.
63 Refitting is now a reversal of the removal
procedure, tensioning the drivebelt as
described in the previous sub-Section. Ensure
that the pinch-bolt securing the lower
suspension arm balljoint to the spindle carrier
locates in the annular groove on the balljoint
spindle. Secure the track rod and balljoint,
using a new split pin. Tighten the suspension
components to their specified torque (see
Chapter 10).
64 Check the level of the transmission oil,
and top-up as required (see Chapter 1).
Modulator belt-break switch
65 Modulator belt-break switches are fitted
to each of the two drivebelt covers, and clip
into position. To remove, gently squeeze the
protruding lever on the switch towards the
main switch body and lift out, ensuring that
the belt contact arm does not catch on the
drivebelt cover.
25 Load-apportioning valve (ABS models) - adjustment

1Before attempting to adjust the load-
apportioning valves, the vehicle must be at its
kerb weight, ie with approximately half a tank
of fuel and carrying no load. Note that a
special setting tool will be required to adjust
the valves - this can be fabricated, to the
dimensions shown (see illustration).
2 Raise the vehicle on ramps or drive it over
an inspection pit, so that working clearance is
obtained with the full weight of the vehicle
resting on its roadwheels. Remove the spare
wheel and its carrier.
3 To check adjustment, insert the load-
apportioning valve setting tool into the nylon
sleeve without pre-loading the valve. If unable
to insert the tool, carry out the following
adjustment procedure.
4 Slacken the operating link adjustment fixing
screw then insert the setting tool into the
nylon sleeve, applying light pressure to the
operating link upper arm, so that the setting
tool fully locates. With the setting tool just
resting up against the adjustment post,
tighten the operating link adjustment fixing
screw to the specified torque (see
illustration) .
5 Repeat the procedure on the other valve.
6 Refit the spare wheel on completion.
