12Make sure the adjuster assembly is
properly engaged with its respective notch in
the handbrake lever.
13When refitting the automatic adjustment
mechanism, fit the lever on the shoe first (see
illustration), then hook the lower end of the
spring onto the lever and the upper end into
its hole in the front shoe (see illustration).
14When you’re done, the brake assembly
should look like this (see illustration). Now
proceed to the other brake.
15When you’re done with both brakes, refit
the brake drums.
16If the wheel cylinder was renewed (see
Note 2), bleed the hydraulic system as
described in Section 16.
17Depress the brake pedal repeatedly to
actuate the self-adjusting mechanism. A
clicking sound will be heard from the brake
drums as the adjusters take up the slack.
18Check the handbrake adjustment (Sec-
tion 11).
19Refit the wheels and bolts. Lower the
vehicle to the ground, and tighten the wheel
bolts to the torque listed in the Chapter 1
Specifications. Check the operation of the
brakes carefully before driving the vehicle in
traffic.
7 Master cylinder-
removal and refitting
3
Warning: Brake fluid is
poisonous. It is also an effective
paint stripper. Refer to the
warning at the start of Section 16.
Note: Although master cylinder parts and
overhaul kits are available for most models, we
recommend fitting a new or overhauled
master cylinder complete. It will take you more
time to overhaul the master cylinder than to
renew it, and you can’t even determine
whether the master cylinder is in good enough
condition to overhaul it until you have
dismantled it. You may very well find that itcan’t be overhauled because of its internal
condition.
Removal
1The master cylinder is connected to the
brake vacuum servo, and both are attached to
the bulkhead, located on the left-hand side of
the engine compartment (see illustration).
2Remove as much fluid as you can from the
reservoir with a syringe.
3Place rags under the line fittings, and
prepare caps or plastic bags to cover the
ends of the lines once they are disconnected.
Caution: Brake fluid will damage
paint. Cover all body parts, and
be careful not to spill fluid during
this procedure.
4Loosen the union nuts at the ends of the
brake lines where they enter the master
cylinder. To prevent rounding off the flats on
these nuts, a split ring (“brake”) spanner,
which wraps around the nut, should be used.
5Pull the brake lines away from the master
cylinder slightly, and plug the ends to prevent
dirt contamination and further fluid loss.
6Disconnect any electrical connectors at the
master cylinder, then remove the nutsattaching the master cylinder to the brake
servo. Pull the master cylinder off the studs,
and lift it out of the engine compartment.
Again, be careful not to spill fluid as this is
done. Discard the old O-ring (see illustration)
between the master cylinder and the servo
unit.
Warning: The O-ring should
always be renewed. A faulty O-
ring can cause a vacuum leak,
which can reduce braking performance
and cause an erratic idle.
Bleeding procedure
7Before fitting a new or overhauled master
cylinder, it should be bled on the bench.
Because it will be necessary to apply pressure
to the master cylinder piston and, at the same
time, control flow from the brake line outlets, it
is recommended that the master cylinder be
mounted in a vice. Use a vice with protected
jaws, and don’t clamp the vice too tightly, or
the master cylinder body might crack.
8Insert threaded plugs into the brake line
outlet holes. Tighten them down so that there
will be no air leakage past them, but not so
tight that they cannot be easily loosened.
9Fill the reservoir with brake fluid of the
recommended type (see “Lubricants, fluids
and capacities” in Chapter 1).
10Remove one plug, and push the piston
assembly into the master cylinder bore to
Braking system 9•9

should look! 6.13b . . . then hook the lower end of the
spring onto the lever as shown; stretch the
spring, and hook the upper end into its

adjuster mechanism . . .
7.6 Always renew the O-ring (1) - groove

7.1 To remove the master cylinder, unplug
the electrical connector (top arrow),
disconnect the brake fluid hydraulic line

expel the air from the master cylinder. A large
Phillips screwdriver can be used to push on
the piston assembly.
11To prevent air from being drawn back into
the master cylinder, the plug must be refitted
and tightened down before releasing the
pressure on the piston assembly.
12Repeat the procedure until brake fluid free
of air bubbles is expelled from the brake line
outlet hole. Repeat the procedure with the
other outlet hole and plug. Be sure to keep the
master cylinder reservoir filled with brake
fluid, to prevent the introduction of air into the
system.
13High pressure is not involved in the bench
bleeding procedure, so the plugs described
above need not be refitted each time the
piston is released, if wished. Instead, before
releasing the piston, simply put your finger
tightly over the hole to keep air from being
drawn back into the master cylinder. Wait
several seconds for brake fluid to be drawn
from the reservoir into the piston bore, then
depress the piston again, removing your
finger as brake fluid is expelled. Be sure to put
your finger back over the hole each time
before releasing the piston, and when the
bleeding procedure is complete for that outlet,
refit the plug and tighten it up before going on
to the other port.
Refitting
14Refit the master cylinder (together with a
new O-ring) over the studs on the brake servo,
and tighten the mounting nuts only finger-tight
at this time.
15Thread the brake line fittings into the
master cylinder. Since the master cylinder is
still a bit loose, it can be moved slightly in
order for the fittings to thread in easily. Do not
strip the threads as the fittings are tightened.
16Tighten the brake fittings securely, and
the mounting nuts to the torque listed in this
Chapter’s Specifications.
17Fill the master cylinder reservoir with fluid,
then bleed the master cylinder (only if the
cylinder has not already been bled) and the
brake system as described in Section 16.
18To bleed the cylinder on the vehicle, have
an assistant pump the brake pedal severaltimes and then hold the pedal to the floor.
Loosen the fitting nut to allow air and fluid to
escape, then tighten the nut. Repeat this
procedure on both fittings until the fluid is
clear of air bubbles. Test the operation of the
brake system carefully before returning the
vehicle to normal service.
8 Brake vacuum servo-
check, removal and refitting
3
Operating check
1Depress the brake pedal several times with
the engine off, until there is no change in the
pedal travel.
2Depress and hold the pedal, then start the
engine. If the pedal goes down slightly,
operation is normal.
Airtightness check
3Start the engine, and turn it off after one or
two minutes. Depress the brake pedal several
times slowly. If the pedal goes down further
the first time but gradually rises after the
second or third depression, the servo is
airtight.
4Depress the brake pedal while the engine is
running, then stop the engine with the pedal
depressed. If there is no change in the pedal
travel after holding the pedal for 30 seconds,
the servo is airtight.
Removal and refitting
5Dismantling the vacuum servo requires
special tools, and cannot be performed by the
home mechanic. If a problem develops, it is
recommended that a new unit be fitted.
6Remove the master cylinder as described in
Section 7.
7Disconnect the vacuum hose from the
brake servo.
8Working in the passenger compartment,
remove the glovebox and lower left-hand trim
panels.
9Remove the clip and clevis pin to
disconnect the pushrod from the cross-shaft
lever (right-hand-drive models) or brake pedal(left-hand-drive models) (see illustration). On
left-hand-drive models, also disconnect the
brake pedal return spring.
10Remove the four mounting nuts (see
illustration)and withdraw the servo unit from
the engine compartment.
11Inspect the small foam filter (see
illustration)inside the rubber boot on the
pushrod. If the filter is clogged, it may affect
the servo’s performance. To clean the filter,
wash it in a mild soapy solution. If it’s still
dirty, renew it.
12Refitting is the reverse of the removal
procedure. Tighten the brake servo mounting
nuts to the torque listed in this Chapter’s
Specifications. Before you slide the boot into
place over the servo pushrod air filter, make
sure the notches in the filter offset the notches
in the damper by 180 degrees.
13On 3-Series models, adjust the basic
setting of the pushrod’s threaded clevis until
the dimension is correct (see illustration).
When the basic setting is correct, tighten the
locknut, then adjust the brake pedal travel and

9 Hydraulic brake servo-
description, removal and
refitting
3
Warning: Brake fluid is
poisonous. It is also an effective
paint stripper. Refer to the
warning at the start of Section 16.
Description
1On 5-Series E28 (“old-shape”) models, a
hydraulic brake servo system is fitted. The
servo unit, located between the brake pedal
(left-hand-drive) or cross-shaft lever (right-
hand-drive) and the master cylinder, is
operated by hydraulic pressure generated by
the power steering pump. When the engine is
running, the power steering pump supplies
hydraulic pressure to a power flow regulator/
accumulator. The regulator/accumulator
stores and regulates the pressure to the
hydraulic brake servo. When you press the
brake pedal, the pressure in the servo helps
actuate the master cylinder, reducing pedal
effort.
2The hydraulic brake servo cannot be
overhauled; if it fails, a new one must be fitted.
Testing the system requires special tools, so
even fault diagnosis is beyond the scope of
the home mechanic. If the system fails, take it
to a dealer service department or other
qualified garage for repairs.
Removal and refitting
3With the engine off, discharge the hydraulic
accumulator by depressing the brake pedal
20 times or more.
4Remove the master cylinder (see Section 7).
5Clean the area around the return and
supply line fittings, then disconnect them.
Plug the lines, to prevent dirt from entering the
system, and to prevent further fluid loss.
Caution: Even a particle of dirt
can damage the servo, so be
extremely careful to prevent dirt
from entering the system while
the lines are disconnected.
6Working from inside the passenger
compartment, remove the lower left trim
panels above the brake pedal (left-hand-drive
models) or glovebox and trim (right-hand-drive models). On left-hand-drive models, also
disconnect the pedal return spring.
7Prise off the retaining clip, and disconnect
the pushrod from the brake pedal (see
illustration 8.9) or cross-shaft lever.
8Remove the four mounting nuts and
remove the brake servo (see illus-
tration 8.10).
9Refitting is the reverse of removal. Tighten
the hydraulic lines to the torque listed in this
Chapter’s Specifications. Note:Don’t try to
tighten these fittings without a torque wrench.
If they’re loose, they can leak, which can affect
system operation; if they’re tight, they can be
damaged, and they’ll also leak. You’ll need a
crowfoot-type split ring (“brake”) attachment
for your torque wrench to tighten the fittings
properly.
10When you’re done, bleed the brake
hydraulic system (Section 16) and adjust the
brake pedal travel and the stop-light switch
(see Section 13).
10 Handbrake cable(s)- renewal
2
1Peel back the boot at the base of the
handbrake lever, and remove the handbrake
cable adjusting nut (see illustration)which
also secures the cable to the handbrake lever.There are two cables - one for each rear wheel
- and a nut for each cable. On some models, it
may be necessary to remove the centre
console completely for access.
2Raise the vehicle and support it securely on
axle stands.
3Remove the rear brake drum (see Section 6)
or rear brake disc (see Section 5).
4On rear drum models, unhook the
handbrake cable from the lever on the rear
brake shoe (see Section 6). On rear disc
models, remove the handbrake shoes and the
actuator (see Section 12) and unhook the
handbrake cable from the actuator (see
illustrations).
5On rear drum models, pull the cable and
cable conduit (tube) out of the back of the
brake backplate, then detach the cable
conduit from the cable clips on the back of
the trailing arm (it’s easier to pull out the old
cable, and fit the new cable, with the conduit
straight instead of curved). On rear disc
models, it’s unnecessary to detach the cable
conduit from the brake backplate, but it’s a
good idea to detach the conduit from the clips
and guides securing it to the trailing arm, to
take some of the bend out of the conduit.
6Working from the wheel end of the cable
conduit, pull the cable out of the conduit (see
illustration).
7Lubricate the new cable with multi-purpose
grease, then insert it into the cable conduit

then back off the adjuster until the shoes
don’t drag (see Section 11). Refit the wheel
bolts, and tighten them to the torque given in
Chapter 1 Specifications.
13 Brake pedal- adjustment
1
Note:You should always adjust brake pedal
height after the master cylinder or brake servo
has been removed or renewed. You should
also adjust the stop-light switch (see Sec-
tion 14).
1Measure the distance between the lower
edge of the brake pedal footpad (ie the edge
furthest from the bulkhead) and the bulkhead
(see illustration), and compare your
measurement with the dimension listed in this
Chapter’s Specifications. If it’s not as listed,
loosen the locknut on the pushrod, and rotatethe pushrod while holding the clevis stationary
until the distance is correct. Note:On right-
hand-drive models, the adjustment is carried
out at the left-hand side of the cross-shaft,
after removing the glovebox, but the
dimension is still measured at the pedal.
14 Stop-light switch-
check and adjustment
1
Note:The stop-light switch should be
checked and, if necessary, adjusted after the
master cylinder or brake servo has been
removed or renewed.
1The stop-light switch is located on a
bracket at the top of the brake pedal. The
switch activates the brake lights whenever the
pedal is depressed.
2With the brake pedal in the rest position,
measure the distance between the switch
contact point on the brake pedal and the
switch housing (see illustration)and
compare your measurement with dimension A
listed in this Chapter’s Specifications.
3If your measurement is outside theindicated dimension, disconnect the wires
from the switch. Loosen the locknuts, screw
the switch in or out until the plunger
dimension is correct, and retighten the
locknuts. Reconnect the wires and check for
correct operation.
15 Brake hoses and lines-
inspection and renewal
4
Warning: Brake fluid is
poisonous. It is also an effective
paint stripper. Refer to the
warning at the start of Section 16.
Inspection
1At the intervals specified in Chapter 1, the
brake hoses and lines should be inspected.
With the vehicle raised and placed securely
on axle stands, the flexible hoses should be
checked for cracks, chafing of the outer
cover, leaks, blisters and other damage.
These are important and vulnerable parts of
the brake system, and inspection should be
thorough. The metal pipes should be checked
for excessive pitting and corrosion. If a hose
or pipe exhibits any of the conditions
described, renew it.
Flexible hose renewal
2Clean all dirt away from the ends of the
hose. Have ready a suitable container to catch
spilled brake fluid when the hose is
disconnected.
3To disconnect the hose at the chassis end,
use a spanner to hold the hex-shaped fitting
on the end of the flexible hose, and loosen the
nut on the metal brake line (see illustration).
If the nut is stuck, soak it with penetrating oil.
After the hose is disconnected from the metal
line, remove the spring clip from the bracket
and detach the hose from the bracket.
4To detach the flexible hose from the caliper,

simply unscrew it. Plug the open fitting in the
caliper if the hose is removed for any length of
time, to prevent dirt ingress.
5Refitting is the reverse of the removal
procedure. Make sure the brackets are in
good condition and the locknuts are securely
tightened. Renew the spring clips if they don’t
fit tightly.
6Carefully check to make sure the
suspension and steering components do not
make contact with the hoses. Have an
assistant turn the steering wheel from lock-to-
lock during inspection.
7Bleed the brake system as described in
Section 16.
Metal brake line renewal
8When renewing brake lines, use genuine
parts only - preferably from a BMW dealer.
9Genuine BMW brake lines are supplied
straight. You’ll need a pipe-bending tool to
bend them to the proper shape.
10First, remove the line you intend to renew,
lay it on a clean workbench and measure it
carefully. Obtain a new line of the same
length, and bend it to match the pattern of the
old line.
Warning: Do not crimp or
damage the line. No bend should
have a smaller radius than
14 mm. Make sure the protective
coating on the new line is undamaged at
the bends.
11When fitting the new line, make sure it’s
well supported by the brackets, that the
routing matches the original, and that there’s
plenty of clearance between movable
components or those components which will
become hot.
12After refitting, check the master cylinder
fluid level, and add fluid as necessary. Bleed
the brake system as outlined in Section 16,
and test the brakes carefully before driving the
vehicle. Be sure there are no leaks.
16 Brake hydraulic system-
bleeding
3
Warning: Wear eye protection
when bleeding the brake system.
If the fluid comes in contact with
your eyes, immediately rinse
them with water, and seek medical
attention. Most types of brake fluid are
highly flammable, and may ignite if spilled
onto hot engine components, for example.
In this respect, brake fluid should be
treated with as much care as if it were
petrol. When topping-up or renewing the
fluid, always use the recommended type,
and ensure that it comes from a freshly-
opened sealed container. Never re-use old
brake fluid bled from the system, and don’t
top-up with fluid which has been standing
open for a long time, as it is potentially
dangerous to do so.
Note:Bleeding the hydraulic system is
necessary to remove any air which has
entered the system during removal and
refitting of a hose, line, caliper or master
cylinder.
1It will probably be necessary to bleed the
system at all four brakes if air has entered the
system due to low fluid level, or if the brake
lines have been disconnected at the master
cylinder.
2If a brake line was disconnected at only one
wheel, then only that caliper or wheel cylinder
need be bled.
3If a brake line is disconnected at a fitting
located between the master cylinder and any
of the brakes, that part of the system served
by the disconnected line must be bled.
4Bleed the right rear, the left rear, the right
front and the left front brake, in that order,
when the entire system is involved.
5Remove any residual vacuum from the
brake servo by applying the brakes about 30
times with the engine off. This will also relieve
any pressure in the anti-lock brake system
(where applicable).
6Remove the master cylinder reservoir
cover, and fill the reservoir with brake fluid.
Refit the cover. Note:Check the fluid level
often during the bleeding operation, and add
fluid as necessary to prevent the fluid level
from falling low enough to allow air into the
master cylinder.
7Have an assistant on hand, an empty clear
plastic container, and a length of clear plastic
or vinyl tubing to fit over the bleed screws.
Alternatively, a “one-man” bleeding kit can be
used. A “one-man” kit usually contains a tubeor bottle with a one-way valve incorporated -
in this way, the pedal can be pumped as
normal, but air is not drawn back into the
system when the pedal is released. If a one-
man kit is used, follow the instructions
provided with it; similarly with pressure
bleeding kits. In any case, you will also need a
supply of new brake fluid of the
recommended type, and a spanner for the
bleed screw.
8Beginning at the right rear wheel, loosen the
bleed screw slightly, then tighten it to a point
where it is tight but can still be loosened
quickly and easily.
9Place one end of the tubing over the bleed
nipple, and submerge the other end in brake
fluid in the container (see illustration).
10Have the assistant pump the brakes a few
times, then hold the pedal firmly depressed.
Note:If the vehicle is equipped with ABS,
have the assistant pump the pedal at least 12
times.
11While the pedal is held depressed, open
the bleed screw just enough to allow a flow of
fluid to leave the caliper or wheel cylinder.
Your assistant should press the brake pedal
smoothly to the floor, and hold it there. Watch
for air bubbles coming out of the submerged
end of the tube. When the fluid flow slows
after a couple of seconds, close the screw
and have your assistant release the pedal.
12Repeat paragraphs 10 and 11 until no
more air is seen leaving the tube, then tighten
the bleed screw and proceed to the left rear
wheel, the right front wheel and the left front
wheel, in that order, and perform the same
procedure. Be sure to check the fluid in the
master cylinder reservoir frequently.
Warning: Never re-use old brake
fluid. It absorbs moisture from
the atmosphere, which can allow
the fluid to boil and render the
brakes inoperative.
13Refill the master cylinder with fluid at the
end of the operation.
14Check the operation of the brakes. The
pedal should feel solid when depressed, with
no sponginess. If necessary, repeat the entire
process. Do not operate the vehicle if you are
in doubt about the effectiveness of the brake
system.

1 General information
These models feature an all-steel welded
construction, where the floorpan and body
components are welded together and
attached to separate front and rear subframe
assemblies. Certain components are
particularly vulnerable to accident damage,
and can be unbolted and repaired or renewed.
Among these parts are the body mouldings,
bumpers, bonnet, doors, tailgate, and all
glass.
Only general body maintenance procedures
and body panel repair procedures within the
scope of the do-it-yourselfer are included in
this Chapter.
2 Bodywork and underframe-
maintenance
1
The general condition of a vehicle’s
bodywork is the one thing that significantly
affects its value. Maintenance is easy, but
needs to be regular. Neglect, particularly after
minor damage, can lead quickly to further
deterioration and costly repair bills. It is
important also to keep watch on those parts
of the vehicle not immediately visible, for
instance the underside, inside all the wheelarches, and the lower part of the engine
compartment.
The basic maintenance routine for the
bodywork is washing - preferably with a lot of
water, from a hose. This will remove all the
loose solids which may have stuck to the
vehicle. It is important to flush these off in
such a way as to prevent grit from scratching
the finish. The wheel arches and underframe
need washing in the same way, to remove any
accumulated mud, which will retain moisture
and tend to encourage rust. Paradoxically
enough, the best time to clean the underframe
and wheel arches is in wet weather, when the
mud is thoroughly wet and soft. In very wet
weather, the underframe is usually cleaned of
large accumulations automatically, and this is
a good time for inspection.
Periodically, except on vehicles with a wax-
based underbody protective coating, it is a
good idea to have the whole of the
underframe of the vehicle steam-cleaned,
engine compartment included, so that a
thorough inspection can be carried out to see
what minor repairs and renovations are
necessary. Steam-cleaning is available at
many garages, and is necessary for the
removal of the accumulation of oily grime,
which sometimes is allowed to become thick
in certain areas. If steam-cleaning facilities are
not available, there are some excellent grease
solvents available which can be brush-
applied; the dirt can then be simply hosed off.
Note that these methods should not be usedon vehicles with wax-based underbody
protective coating, or the coating will be
removed. Such vehicles should be inspected
annually, preferably just prior to Winter, when
the underbody should be washed down, and
any damage to the wax coating repaired.
Ideally, a completely fresh coat should be
applied. It would also be worth considering
the use of such wax-based protection for
injection into door panels, sills, box sections,
etc, as an additional safeguard against rust
damage, where such protection is not
provided by the vehicle manufacturer.
After washing paintwork, wipe off with a
chamois leather to give an unspotted clear
finish. A coat of clear protective wax polish will
give added protection against chemical
pollutants in the air. If the paintwork sheen has
dulled or oxidised, use a cleaner/polisher
combination to restore the brilliance of the
shine. This requires a little effort, but such
dulling is usually caused because regular
washing has been neglected. Care needs to be
taken with metallic paintwork, as special non-
abrasive cleaner/polisher is required to avoid
damage to the finish. Always check that the
door and ventilator opening drain holes and
pipes are completely clear, so that water can
be drained out. Brightwork should be treated in
the same way as paintwork. Windscreens and
windows can be kept clear of the smeary film
which often appears, by the use of proprietary
glass cleaner. Never use any form of wax or
other body or chromium polish on glass.

MOT Test Checks
This is a guide to getting your vehicle through the MOT test.
Obviously it will not be possible to examine the vehicle to the same
standard as the professional MOT tester. However, working through
the following checks will enable you to identify any problem areas
before submitting the vehicle for the test.
Where a testable component is in borderline condition, the tester
has discretion in deciding whether to pass or fail it. The basis of such
discretion is whether the tester would be happy for a close relative or
friend to use the vehicle with the component in that condition. If the
vehicle presented is clean and evidently well cared for, the tester may
be more inclined to pass a borderline component than if the vehicle is
scruffy and apparently neglected.
It has only been possible to summarise the test requirements here,
based on the regulations in force at the time of printing. Test standards
are becoming increasingly stringent, although there are some
exemptions for older vehicles. For full details obtain a copy of the Haynes
publication Pass the MOT! (available from stockists of Haynes manuals).
An assistant will be needed to help carry out some of these checks.
The checks have been sub-divided into four categories, as follows:
HandbrakeMTest the operation of the handbrake.
Excessive travel (too many clicks) indicates
incorrect brake or cable adjustment.
MCheck that the handbrake cannot be
released by tapping the lever sideways. Check
the security of the lever mountings.
Footbrake
MDepress the brake pedal and check that it
does not creep down to the floor, indicating a
master cylinder fault. Release the pedal, wait
a few seconds, then depress it again. If the
pedal travels nearly to the floor before firm
resistance is felt, brake adjustment or repair is
necessary. If the pedal feels spongy, there is
air in the hydraulic system which must be
removed by bleeding.MCheck that the brake pedal is secure and in
good condition. Check also for signs of fluid
leaks on the pedal, floor or carpets, which
would indicate failed seals in the brake master
cylinder.
MCheck the servo unit (when applicable) by
operating the brake pedal several times, then
keeping the pedal depressed and starting the
engine. As the engine starts, the pedal will
move down slightly. If not, the vacuum hose or
the servo itself may be faulty.
Steering wheel and column
MExamine the steering wheel for fractures or
looseness of the hub, spokes or rim.
MMove the steering wheel from side to side
and then up and down. Check that the
steering wheel is not loose on the column,
indicating wear or a loose retaining nut.
Continue moving the steering wheel as before,
but also turn it slightly from left to right.
MCheck that the steering wheel is not loose
on the column, and that there is no abnormalmovement of the steering wheel, indicating
wear in the column support bearings or
couplings.
Windscreen and mirrors
MThe windscreen must be free of cracks or
other significant damage within the driver’s
field of view. (Small stone chips are
acceptable.) Rear view mirrors must be
secure, intact, and capable of being adjusted.
