1993 FORD MONDEO brake pads

15Coolant hydrometers are available at
most automotive accessory shops. If the
specific gravity of a sample taken from the
expansion tank (when the engine is switched
off and fully cooled down) is less than that
specified, the coolant mixture strength has
fallen below the minimum. If this is found,
either the coolant strength must be restored
by adding neat antifreeze to Ford’s
specification (if that is what is in the system)
or by draining and flushing the system, then
refilling it with fresh coolant mixture of the
correct ratio (if any other type of antifreeze is
being used).
16When checking the coolant level, always
note its condition; it should be relatively clear.
If it is brown or rust-coloured, the system
should be drained, flushed and refilled. If
antifreeze has been used which does not
meet Ford’s specification, its corrosion
inhibitors will lose their effectiveness with
time; such coolant must be renewed regularly,
even if it appears to be in good condition,
usually at the intervals suggested at the
beginning of Section 2 of this Chapter.
Windscreen/tailgate and
headlight washer fluid
17Fluid for the windscreen/tailgate washer
system (and where applicable the headlight
washer system) is stored in a plastic reservoir,
which is located at the right front corner of the
engine compartment. In milder climates, plain
water can be used to top-up the reservoir, but
the reservoir should be kept no more than
two-thirds full, to allow for expansion should
the water freeze. In colder climates, the use of
a specially-formulated windscreen washer
fluid, available at your dealer or any car
accessory shop, will help lower the freezing
point of the fluid (see illustration). Do notuse
regular (engine) antifreeze - it will damage the
vehicle’s paintwork.
Battery electrolyte
18On models not equipped with a sealed
battery (see Section 9), check the electrolyte
level of all six battery cells. The level must be
approximately 10 mm above the plates; this
may be shown by maximum and minimum
level lines marked on the battery’s casing (seeillustration). If the level is low, use a coin to
release the filler/vent cap, and add distilled
water. Install and securely retighten the cap.
Caution: Overfilling the cells may
cause electrolyte to spill over
during periods of heavy charging,
causing corrosion or damage.
Refer also to the warning at the beginning
of Section 9.
Brake fluid
19The brake fluid reservoir is located on the
top of the brake master cylinder, which is
attached to the front of the vacuum servo unit.
The “MAX” and “MIN” marks are indicated on
the side of the translucent reservoir, and the
fluid level should be maintained between
these marks at all times (see illustration).
20The brake fluid inside the reservoir is
readily visible. With the vehicle on level
ground, the level should normally be on or just
below the “MAX” mark.
21Progressive wear of the brake pads and
brake shoe linings causes the level of the
brake fluid to gradually fall; however, when
the brake pads are renewed, the original level
of the fluid is restored. It is not therefore
necessary to top-up the level to compensate
for this minimal drop, but the level must never
be allowed to fall below the minimum mark.
22If topping-up is necessary, first wipe the
area around the filler cap with a clean rag
before removing the cap. When adding fluid,
pour it carefully into the reservoir, to avoid
spilling it on surrounding painted surfaces
(see illustration). Be sure to use only the
specified hydraulic fluid (see “Lubricants,
fluids and capacities”at the start of this
Chapter) since mixing different types of fluid
can cause damage to the system.
Warning: Brake hydraulic fluid
can harm your eyes and damage
painted surfaces, so use extreme
caution when handling and
pouring it. Wash off spills immediately with
plenty of water. Do not use fluid that has
been standing open for some time, as it
absorbs moisture from the air. Excessmoisture can cause corrosion and a
dangerous loss of braking effectiveness.
23When adding fluid, it is a good idea to
inspect the reservoir for contamination. The
system should be drained and refilled if
deposits, dirt particles or contamination are
seen in the fluid.
24After filling the reservoir to the correct
level, make sure that the cap is refitted
securely, to avoid leaks and the entry of
foreign matter.
25If the reservoir requires repeated
replenishing to maintain the correct level, this
is an indication of an hydraulic leak
somewhere in the system, which should be
investigated immediately.
Power steering fluid
26See Section 5 of this Chapter.
1Periodic inspection of the tyres may spare
you from the inconvenience of being stranded
with a flat tyre. It can also provide you with
vital information regarding possible problems
in the steering and suspension systems
before major damage occurs.
2The original tyres on this vehicle are
equipped with tread wear indicator (TWI)
bands, which will appear when the tread
depth reaches approximately 1.6 mm. Most
tyres have a mark around the tyre at regular
intervals to indicate the location of the tread

evidence of leaks, severe corrosion, or
damage. Make sure that all brackets and
rubber mountings are in good condition, and
tight; if any of the mountings are to be
renewed, ensure that the replacements are of
the correct type (see illustration). Leakage at
any of the joints or in other parts of the system
will usually show up as a black sooty stain in
the vicinity of the leak. Note:Exhaust sealants
should not be used on any part of the exhaust
system upstream of the catalytic converter -
even if the sealant does not contain additives
harmful to the converter, pieces of it may
break off and foul the element, causing local
overheating.
3At the same time, inspect the underside of
the body for holes, corrosion, open seams,
etc. which may allow exhaust gases to enter
the passenger compartment. Seal all body
openings with silicone or body putty.
4Rattles and other noises can often be
traced to the exhaust system, especially the
rubber mountings. Try to move the system,
silencer(s) and catalytic converter. If any
components can touch the body or
suspension parts, secure the exhaust system
with new mountings.
5Check the running condition of the engine
by inspecting inside the end of the tailpipe;
the exhaust deposits here are an indication of
the engine’s state of tune. The inside of the
tailpipe should be dry, and should vary in
colour from dark grey to light grey/brown; if it
is black and sooty, or coated with white
deposits, the engine is in need of a thorough
fuel system inspection.
1With the vehicle raised and supported on
axle stands or over an inspection pit,
thoroughly inspect the underbody and wheel
arches for signs of damage and corrosion. In
particular, examine the bottom of the side
sills, and any concealed areas where mud can
collect. Where corrosion and rust is evident,press and tap firmly on the panel with a
screwdriver, and check for any serious
corrosion which would necessitate repairs. If
the panel is not seriously corroded, clean
away the rust, and apply a new coating of
underseal. Refer to Chapter 11 for more
details of body repairs.
2At the same time, inspect the PVC-coated
lower body panels for stone damage and
general condition.
3Inspect all of the fuel and brake lines on the
underbody for damage, rust, corrosion and
leakage. Also make sure that they are
correctly supported in their clips. Where
applicable, check the PVC coating on the
lines for damage.
Note:For detailed photographs of the brake
system, refer to Chapter 9.
1The work described in this Section should
be carried out at the specified intervals, or
whenever a defect is suspected in the braking
system. Any of the following symptoms could
indicate a potential brake system defect:
(a) The vehicle pulls to one side when the
brake pedal is depressed.
(b) The brakes make scraping or dragging
noises when applied.
(c) Brake pedal travel is excessive.
(d) The brake fluid requires repeated topping-
up.
2A brake pad wear warning light is fitted, and
it is illuminated when the thickness of the front
(or rear) disc brake pad linings reach the
minimum amount. However, a physical check
should be made to confirm the thickness of
the linings, as follows.
Disc brakes
3Jack up the front or rear of the vehicle, as
applicable, and support it on axle stands.
Where rear brake pads are fitted, also jack up
the rear of the vehicle and support on axle
stands.
4For better access to the brake calipers,
remove the wheels.
5Look through the inspection window in thecaliper, and check that the thickness of the
friction lining material on each of the pads is
not less than the recommended minimum
thickness given in the Specifications. Note:
Bear in mind that the lining material is normally
bonded to a metal backing plate.
6If it is difficult to determine the exact
thickness of the pad linings, or if you are at all
concerned about the condition of the pads,
then remove them from the calipers for further
inspection (refer to Chapter 9).
7Check the remaining brake caliper(s) in the
same way.
8If any one of the brake pads has worn down
to, or below, the specified limit, all fourpads
at that end of the car must be renewed as a
set (ie all the front pads or all the rear pads).
9Measure the thickness of the discs with a
micrometer, if available, to make sure that
they still have service life remaining. If any
disc is thinner than the specified minimum
thickness, renew it (refer to Chapter 9). In any
case, check the general condition of the
discs. Look for excessive scoring and
discolouration caused by overheating. If these
conditions exist, remove the relevant disc and
have it resurfaced or renewed (refer to
Chapter 9).
10Before refitting the wheels, check all
brake lines and hoses (refer to Chapter 9). In
particular, check the flexible hoses in the
vicinity of the calipers, where they are
subjected to most movement. Bend them
between the fingers (but do not actually bend
them double, or the casing may be damaged)
and check that this does not reveal
previously-hidden cracks, cuts or splits (see
illustration).
Rear drum brakes
11Chock the front wheels, then jack up the
rear of the vehicle and support on axle stands.
12For better access, remove the rear
wheels.
13To check the brake shoe lining thickness
without removing the brake drums, prise the
rubber plugs from the backplates, and use an
electric torch to inspect the linings of the
leading brake shoes (see illustration). Check
that the thickness of the lining material on the

To prevent the possibility of mixing up spark
plug (HT) leads, it is a good idea to try to work
on one spark plug at a time.
4If the marks on the original-equipment
spark plug (HT) leads cannot be seen, mark
the leads 1 to 4, to correspond to the cylinder
the lead serves (No 1 cylinder is at the timing
belt end of the engine). Pull the leads from the
plugs by gripping the rubber boot sealing thecylinder head cover opening, not the lead,
otherwise the lead connection may be
fractured.
5It is advisable to soak up any water in the
spark plug recesses with a rag, and to remove
any dirt from them using a clean brush,
vacuum cleaner or compressed air before
removing the plugs, to prevent any dirt or
water from dropping into the cylinders. Warning: Wear eye protection
when using compressed air!
6Unscrew the spark plugs, ensuring that the
socket is kept in alignment with each plug - if
the socket is forcibly moved to either side, the
porcelain top of the plug may be broken off. If
any undue difficulty is encountered when
unscrewing any of the spark plugs, carefully

The braking system is of diagonally-split,
dual-circuit design, with ventilated discs at
the front, and drum or disc brakes (according
to model) at the rear. The front calipers are of
floating single-piston design, using asbestos-
free pads. The rear drum brakes are of the
leading and trailing shoe type. They are self-
adjusting during footbrake operation. The rear
brake shoe linings are of different
thicknesses, in order to allow for the different
proportional rates of wear.
Pressure-control relief (PCR) valves are
fitted to the rear brakes, to prevent rear wheel
lock-up under hard braking. The valves are
sometimes referred to as pressure-conscious
reducing valves. On non-ABS models, theyare fitted in the master cylinder rear brake
outlet ports; on ABS models, they are located
on the ABS unit.
When rear disc brakes are fitted, the rear
brake caliper is located on the front of the
knuckle on Saloon and Hatchback models,
and on the rear of the knuckle on Estate
models (see illustration).
The handbrake is cable-operated, and acts
on the rear brakes. On rear drum brake
models, the cables operate on the rear trailing
brake shoe operating levers, and on rear disc
brake models, they operate on levers on the
rear calipers. The handbrake lever
incorporates an automatic adjuster, which
removes any slack from the cables when the
lever is disengaged (see illustration).
Handbrake lever movement remains
consistent at all times, and no adjustment is
necessary or possible.
Where fitted, the anti-lock braking system
(ABS) is of the four-channel low-pressure type
(see illustration). It uses the basic
conventional brake system, together with aBendix ABS hydraulic unit fitted between the
master cylinder and the four wheel brakes.
The hydraulic unit consists of a hydraulic
actuator, an ABS brake pressure pump, an
ABS module with built-in relay box, and two
pressure-control relief valves. Braking at each
of the four wheels is controlled by separate
solenoid valves in the hydraulic actuator. If
wheel lock-up is detected on a wheel when
the vehicle speed is above 3 mph, the valve
opens, releasing pressure to the relevant
brake, until the wheel regains a rotational
speed corresponding to the speed of the
vehicle. The cycle can be repeated many
times a second. In the event of a fault in the
ABS system, the conventional braking system
is not affected. Diagnosis of a fault in the ABS
system requires the use of special equipment,
and this work should therefore be left to a
Ford dealer. Diagnostic connectors are
located on the side of the left-hand front
suspension turret.
The traction control system (TCS) is fitted
as an option to some models, and uses the

basic ABS system, with an additional pump
and valves fitted to the hydraulic actuator (see
illustration). If wheelspin is detected at a
speed below 30 mph, one of the valves
opens, to allow the pump to pressurise the
relevant brake, until the spinning wheel slows
to a rotational speed corresponding to the
speed of the vehicle. This has the effect of
transferring torque to the wheel with mosttraction. At the same time, the throttle plate is
closed slightly, to reduce the torque from the
engine. At speeds above 30 mph, the TCS
operates by throttle plate adjustment only.
Warning: Disc brake pads must
be renewed on both front wheels
at the same time - never renew
the pads on only one wheel, as
uneven braking may result. Although
genuine Ford linings are asbestos-free, the
dust created by wear of non-genuine pads
may contain asbestos, which is a health
hazard. Never blow it out with compressed
air, and don’t inhale any of it. DO NOT use
petroleum-based solvents to clean brake
parts; use brake cleaner or methylated
spirit only. DO NOT allow any brake fluid,
oil or grease to contact the brake pads or
disc. Also refer to the warning at the start
of Section 15 concerning brake fluid.
1Apply the handbrake. Loosen the front
wheel nuts, jack up the front of the vehicle
and support it on axle stands.
2Remove the front wheels. Work on onebrake assembly at a time, using the
assembled brake for reference if necessary.
3Follow the accompanying photos,
beginning with illustration 2.3A, for the pad
removal procedure. Be sure to stay in order,
and read the caption under each illustration.

cracks. If a detailed inspection is necessary,
refer to Section 4.

caliper bore, to provide room for the new
brake pads. A C-clamp can be used to
accomplish this. As the piston is depressed to
the bottom of the caliper bore, the fluid in the
master cylinder will rise slightly. Make sure
that there is sufficient space in the brake fluid
reservoir to accept the displaced fluid, and if
necessary, syphon some off first.
6Fit the new pads using a reversal of the
removal procedure, but tighten the guide
bolts to the torque wrench setting given in the
Specifications at the beginning of this
Chapter.
7On completion, firmly depress the brakepedal a few times, to bring the pads to their
normal working position. Check the level of
the brake fluid in the reservoir, and top-up if
necessary.
8Give the vehicle a short road test, to make
sure that the brakes are functioning correctly,
and to bed-in the new linings to the contours
of the disc. New linings will not provide
maximum braking efficiency until they have
bedded-in; avoid heavy braking as far as
possible for the first hundred miles or so.
Note:Refer to the warning at the beginning of
the previous Section before proceeding.Removal
1Apply the handbrake. Loosen the front
wheel nuts, jack up the front of the vehicle
and support it on axle stands. Remove the
appropriate front wheel.
2Fit a brake hose clamp to the flexible hose
leading to the front brake caliper. This will
minimise brake fluid loss during subsequent
operations (see illustration).
3Loosen (but do not completely unscrew) the
union on the caliper end of the flexible brake
hose (see illustration).

6With the drum in position, refit the wheel,
then carry out the renewal procedure on the
remaining rear brake.
7Lower the vehicle to the ground, and
tighten the wheel nuts.
8Depress the brake pedal several times, in
order to operate the self-adjusting mechanism
and set the shoes at their normal operating
position.
9Make several forward and reverse stops,
and operate the handbrake fully two or three
times. Give the vehicle a road test, to make
sure that the brakes are functioning correctly,
and to bed-in the new linings to the contours
of the disc. Remember that the new linings
will not give full braking efficiency until they
have bedded-in.
Note:Before starting work, check on the
availability of parts (overhaul kit of seals). Also
bear in mind that if the brake shoes have been
contaminated by fluid leaking from the wheel
cylinder, they must be renewed. In principle,
the shoes on BOTH sides of the vehicle must
be renewed, even if they are only
contaminated on one side.
Removal
1Remove the brake drum as described in
Section 5.
2Minimise fluid loss either by removing the
master cylinder reservoir cap, and then
tightening it down onto a piece of polythene
to obtain an airtight seal, or by using a brake
hose clamp, a G-clamp, or similar tool, to
clamp the flexible hose at the nearest
convenient point to the wheel cylinder.
3Pull the brake shoes apart at their top ends,
so that they are just clear of the wheel
cylinder. The automatic adjuster will hold the
shoes in this position, so that the cylinder can
be withdrawn.
4Wipe away all traces of dirt around the
hydraulic union at the rear of the wheel
cylinder, then undo the union nut.5Unscrew the two bolts securing the wheel
cylinder to the backplate (see illustration).
6Withdraw the wheel cylinder from the
backplate so that it is clear of the brake
shoes. Plug the open hydraulic unions, to
prevent the entry of dirt, and to minimise
further fluid loss whilst the cylinder is
detached.
Overhaul
7Clean the external surfaces of the cylinder,
and unscrew the bleed screw.
8Carefully prise off the dust cover from each
end of the cylinder.
9Tap the wheel cylinder on a block of wood
to eject the pistons and seals, keeping them
identified for location. Finally remove the
spring.
10Clean the pistons and the cylinder by
washing in methylated spirit or fresh hydraulic
fluid. Do not use petrol, paraffin or any other
mineral-based fluid. Remove and discard the
old seals, noting which way round they are
fitted.
11Examine the surfaces of the pistons and
the cylinder bores, and look for any signs of
rust or scoring. If such damage is evident, the
complete wheel cylinder must be renewed.
12Reassemble by lubricating the first piston
in clean hydraulic fluid, then manipulating a
new seal into position, so that its raised lip
faces away from the brake shoe bearing face
of the piston.
13Insert the piston into the cylinder. As the
seal enters the bore, twist the piston back and
forth so that the seal lip is not trapped.
14Insert the spring, then refit the remaining
piston and seal, again making sure that the
seal lip is not trapped as it enters the bore.
15Fit new dust covers to the grooves in the
pistons and wheel cylinder body.
16Refit the bleed screw.
Refitting
17Wipe clean the backplate, and remove the
plug from the end of the hydraulic pipe. Fit the
cylinder onto the backplate, and screw in the
hydraulic union nut by hand, being careful not
to cross-thread it.18Tighten the mounting bolts, then fully
tighten the hydraulic union nut.
19Retract the automatic brake adjuster
mechanism, so that the brake shoes engage
with the pistons of the wheel cylinder. To do
this, prise the shoes apart slightly, turn the
automatic adjuster to its minimum position,
and release the shoes.
20Remove the clamp from the flexible brake
hose, or the polythene from the master
cylinder (as applicable).
21Refit the brake drum with reference to
Section 5.
22Bleed the brake hydraulic system as
described in Section 15. Providing suitable
precautions were taken to minimise loss of
fluid, it should only be necessary to bleed the
relevant rear brake.
23Test the brakes carefully before returning
the vehicle to normal service.
Warning: Disc brake pads must
be renewed on BOTH rear wheels
at the same time - never renew
the pads on only one wheel, as
uneven braking may result. Although
genuine Ford linings are asbestos-free, the
dust created by wear of non-genuine pads
may contain asbestos, which is a health
hazard. Never blow it out with compressed
air, and don’t inhale any of it. DO NOT use
petroleum-based solvents to clean brake
parts; use brake cleaner or methylated
spirit only. DO NOT allow any brake fluid,
oil or grease to contact the brake pads or
disc.
1Chock the front wheels, and engage 1st
gear (or “P”). Loosen the rear wheel nuts, jack
up the rear of the vehicle and support it on
axle stands.
2Remove the rear wheels. Work on one
brake assembly at a time, using the
assembled brake for reference if necessary.
3Inspect the rear brake disc as described in
Section 10.
