FORD GRANADA 1985 Service Repair Manual

Models covered in this Manual have disc
brakes fitted all round. The footbrake operates
hydraulically on all four wheels, and the
handbrake operates mechanically on the rear
wheels. Both footbrake and handbrake are
self-adjusting in use.
Ford’s anti-lock braking system (ABS) is
fitted to all models. The system monitors the
rotational speed of each roadwheel. When a
wheel begins to lock under heavy braking, the
ABS reduces the hydraulic pressure to that
wheel, so preventing it from locking. When this
happens a pulsating effect will be noticed at
the brake pedal. On some road surfaces the
tyres may squeal when braking hard even
though the wheels are not locked.
The main components of the system are the
hydraulic unit, the calipers, pads and discs,
the wheel sensors and the “brain” or control
module. The hydraulic unit contains the
elements of a traditional master cylinder, plus
an electric motor and pump, a pressure
accumulator and control valves. The pump is
the source of pressure for the system and
does away with the need for a vacuum servo.
The hydraulic circuit is split front and rear,
as is normal practice with rear-wheel drive
vehicles. In the event that the hydraulic pump
fails, unassisted braking effort is still available
on the front calipers only.
Warning lights inform the driver of low brake
fluid level, ABS failure and (on some models)
brake pad wear. The low fluid level light
doubles as a “handbrake on” light; if it
illuminates at the same time as the ABS
warning light, it warns of low hydraulic
pressure.
ABS cannot overturn the laws of physics:
stopping distances will inevitably be greater on
loose or slippery surfaces. However, the system
should allow even inexperienced drivers to
retain directional control under panic braking.
From August 1986 the following
modifications were made to the braking
system.
a)The relays differ from earlier versions.b)The hydraulic pump is constructed of iron
rather than alloy.
c)A new pressure warning switch is used.
d)The earlier high pressure rubber hose is
replaced by a steel pipe.
To overcome the problem of excessive rear
brake pad wear, Ford introduced a differential
valve which is screwed into the ABS valve
block.The valve limits the pressure applied to
the rear brake calipers and so reduces brake
pad wear. From 1988 onwards, the valve has
been fitted during production. The differential
valve can also be fitted to earlier models. Refer
to your Ford dealer for further information.
From April 1992 onwards, the models
covered in this Manual were equipped with a
new Teves MK IV anti-lock braking system
instead of the Teves MK II system fitted to the
earlier models.
The Teves MK IV system differs from the
earlier MK II system in the following ways.
a)The source of hydraulic pressure for the
system is a conventional master cylinder
and vacuum servo assembly.
b)A valve block and pump assembly is used
instead of the hydraulic control unit. The
block contains the inlet and outlet
solenoid valves that control the hydraulic
system. There are three pairs of valves,
one for each brake circuit (paragraph c).
c)The hydraulic braking system consists of
three separate circuits; one for each front
brake (which are totally independent of
each other), and a joint circuit which
operates both rear brakes.
d)A G (gravity) switch is incorporated in the
system. This is an inertia type switch and
informs the control module when the
vehicle is decelerating rapidly.
e)A Pedal Travel Sensor (PTS) is fitted to the
vacuum servo unit. The PTS informs the
control module of the position of the brake
pedal when the anti-lock sequence starts
and ensures that a constant pedal height
is maintained during the sequence.
The MK IV system operates as follows.
During normal operation the system
functions in the same way as a non-ABS
system would. During this time the three inlet
valves in the valve block are open and theoutlet valves are closed, allowing full hydraulic
pressure present in the master cylinder to act
on the main braking circuit. If the control
module receives a signal from one of the
wheel sensors and senses that a wheel is
about to lock, it closes the relevant inlet valve
in the valve block which then isolates the
brake caliper on the wheel which is about to
lock from the master cylinder, effectively
sealing in the hydraulic pressure. If the speed
of rotation of the wheel continues to decrease
at an abnormal rate, the control module will
then open the relevant outlet valve in the valve
block; this allows the fluid from the relevant
hydraulic circuit to return to the master
cylinder reservoir, releasing pressure on the
brake caliper so that the brake is released. The
pump in the valve block also operates to assist
in the quick release of pressure. Once the
speed of rotation of the wheel returns to an
acceptable rate the pump stops, the outlet
valve closes and the inlet valve is opened,
allowing the hydraulic master cylinder
pressure to return to the caliper which then
reapplies the brake. This cycle can be carried
many times a second. The solenoid valves
connected to the front calipers operate
independently, but the valve connected to the
rear calipers operates both calipers
simultaneously.
The operation of the ABS system is entirely
dependent on electrical signals. To prevent
the system responding to any inaccurate
signals, a built-in safety circuit monitors all
signals received by the control module. If an
inaccurate signal or low battery voltage is
detected, the ABS system is automatically
shut down and the warning lamp on the
instrument cluster is illuminated to inform the
driver that the ABS system is not operational.
Whilst in this state the system functions in the
same way as a non-ABS system would. If a
fault does develop in the ABS system, the car
must be taken to a Ford dealer for fault
diagnosis and repair. The system is equipped
with a diagnostic plug into which a special
diagnostic (STAR) tester can be plugged. This
allows faults to be easily traced.

Note: 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. Finally, it is hygroscopic (it
absorbs moisture from the air) 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
1Bleeding is necessary whenever air has
entered the hydraulic system - for instance
after component renewal. Because the
hydraulic circuits are split, if only the front or
rear circuit has been disturbed it will normally
only be necessary to bleed the front or rear
calipers. If the hydraulic unit has been
disturbed or the fluid level has been allowed to
fall so low that air has entered the system,
both front and rear circuits must be bled,
starting with the front
2The services of an assistant will be required.
As far as is known, pressure bleeding or other
“one-man” equipment cannot be used. In
addition a supply of fresh brake fluid of the
correct type will be needed, together with a
length of flexible tube to fit the bleed screws
and a clean glass or plastic container.
3Do not allow the hydraulic unit pump motor
to run for more than two minutes at a time. The
motor must be allowed to cool (with the
ignition off) for at least ten minutes after each
two minute spell of running.
4Remember that brake fluid is poisonous and
that the rear brake hydraulic system may be
under considerable pressure. Take care not to
allow hydraulic fluid to spray into the face or
eyes.
5Keep the reservoir topped up to the MAX
mark during bleeding.
6Discard the fluid bled out of the system as it
is unfit for re-use.

7Remove the dust cap (if fitted) from the left-
hand caliper bleed screw. Slacken the bleed
screw, then nip it up again. Make sure that the
ignition is off.8Fit the bleed tube over the bleed screw.
Place the other end of the tube in the bleed jar
(glass or plastic container). Pour sufficient
brake fluid into the jar to cover the end of the
tube.
9Open the bleed screw one full turn. Have
the assistant depress the brake pedal as far as
it will go, and hold it depressed. Tighten the
bleed screw, then tell the assistant to release
the pedal.
10Repeat paragraph 9 until clean fluid, free
of air bubbles, flows from the bleed screw
during the downstrokes. Remember to keep
the fluid reservoir topped up.
11Repeat the operations on the right-hand
caliper. Refit the bleed screw dust caps (if
applicable) on completion.
Rear brakes
12Remove the dust cap (if fitted) from the
rear left-hand caliper bleed screw. Open the
bleed screw one full turn.
13Fit the bleed tube over the bleed screw.
Place the other end of the tube in the bleed jar
(see illustration).
14Have the assistant depress the brake
pedal as far as it will go and hold it down.
Switch on the ignition: the hydraulic unit pump
will start and fluid will flow from the bleed
screw.
15When clean fluid, free of air bubbles,
emerges from the bleed screw, tighten the
bleed screw and have the assistant release the
pedal.
16Wait for the hydraulic unit pump to stop,
then top-up the reservoir and repeat the
procedure on the right-hand caliper. This time
the brake pedal should only be depressed
half-way.
17Switch off the ignition, top-up the reservoir
again and refit the reservoir cap. Refit the
bleed screw dust caps (if applicable).
Models from April 1992
18This operation can be carried out using the
information given above inparagraphs 1 to 10,
ignoring the reference to the hydraulic unit
pump and bearing in mind the following.
19Note that if only one circuit is disturbed it
will only be necessary to bleed that relevant
circuit on completion.20If the complete system is to be bled, it
should be done in the following order.
a)Left-hand front caliper.
b)Right-hand front brake caliper.
c)Left-hand rear caliper.
d)Right-hand rear caliper.
See Chapter 1, Section 44.
1Whenever the brake pads are inspected,
also inspect the brake discs for deep
scratches, scores or cracks. Light scoring is
normal and may be ignored. A cracked disc
must be renewed; scratches and scores can
sometimes be machined out, provided that the
thickness of the disc is not reduced below the
specified minimum.
2When the brake pads are renewed, or if
brake judder or snatch is noticed, check the
discs for run-out and thickness variation. (Note
that wheel bearing wear can cause disc run-
out.)
3Position a dial test indicator probe against
the disc wear face, approximately 15 mm (0.6 in)
in from the outer circumference. Zero the
indicator, rotate the disc and read the run-out
from the indicator(see illustration).Maximum
run-out is given in the Specifications. If a dial
test indicator is not available, use a fixed
pointer and feeler blades.
4Measure the thickness of the disc, using a
micrometer, in eight evenly spaced positions
around the disc. Maximum thickness variation
is given in the Specifications. Renew the disc if
the variation is out of limits.
1Slacken the front wheel nuts, raise and
support the vehicle and remove the relevant
front wheel.

and bracket off the disc and tie them up out of
the way. Do not allow the caliper to hang on
the flexible hose.
3Remove the spring clip which secures the
disc (see illustration).
4Mark the relationship of the disc to the hub
if it is to be re-used, then remove the disc.
5Refit by reversing the removal operations.
Tighten the caliper bracket bolts to the
specified torque, and check that the brake
flexible hose is not kinked or fouling in any
position of the steering wheel.
6Pump the brake pedal to bring the pads up
to the disc.
1Chock the front wheels and release the
handbrake. Slacken the rear wheel nuts, raise
and support the vehicle and remove the
relevant rear wheel.
2Free the handbrake cable from its clip in the
suspension lower arm.
3Remove the two bolts which secure the
caliper bracket to the hub. Lift the caliper and
bracket off the disc and suspend it without
straining the flexible hose.
4Remove the spring clip from the wheel stud.
Mark the disc-to-hub relationship and remove
the disc.
5Refit by reversing the removal operations.
6Pump the brake pedal to bring the pads up
to the disc.1Disc pads can be inspected without
removing the front wheels, using a mirror and
a torch through the aperture in the rear face of
the caliper. If any one pad is worn down to the
minimum specified, all four pads (on both front
wheels) must be renewed.
2To renew the pads, first remove the front
wheels, then prise free the spring clip from the
outboard face of a caliper (see illustration).
3Disconnect the pad wear warning wires,
when fitted (see illustration).
4Unscrew the two caliper slide bolts, using
a 7 mm hexagon key, until the caliper is free
of the bracket (see illustration).
5Lift the caliper off the disc and remove the
pads (see illustration). Support the caliper so
that the flexible hose is not strained. Do not
press the brake pedal with the caliper removed.
6Clean the dust and dirt from the caliper,
bracket and disc, using a damp cloth or old
paintbrush which can be thrown away
afterwards. Take care not to disperse the dust
into the air, or to inhale it, since it may contain
asbestos. Scrape any scale or rust from the
disc. Investigate any hydraulic fluid leaks.
7Push the caliper piston back into its
housing, using the fingers or a blunt
instrument, to accommodate the extra
thickness of the new pads.
8Fit the new pads to the caliper, being careful
not to contaminate the friction surfaces with oilor grease. The inboard pad has a spring clip
which fits into the piston recess; the outboard
pad must have its backing paper peeled off,
after which the pad should be stuck to the
other side of the caliper (see illustrations).
9Fit the caliper and pads over the disc and
onto the caliper bracket. Tighten the slide
bolts to the specified torque.
10Reconnect the wear warning wires, if fitted.
11Refit the spring clip to the caliper.
12Repeat the operations on the other caliper,
then refit the wheels and lower the vehicle.
Tighten the wheel nuts.
13Pump the brake pedal several times to
bring the pads up to the disc, then check the
brake fluid level.
14Avoid heavy braking as far as possible for
the first hundred miles or so to allow the new
pads to bed in.7Front brake pads - inspection

1It is necessary to remove the rear wheels in
order to inspect the rear pads. The pads can
be viewed through the top of the caliper after
removing the spring clip. If any one pad is
worn down to the minimum specified, all four
pads (on both rear wheels) must be renewed.
2Free the handbrake cable from its clip on
the suspension lower arm. Release the
handbrake.
3Remove the caliper slide bolt nearest the
front, counter-holding the slide pin with
another spanner (see illustration).
4Disconnect the pad wear warning wires,
when fitted (see illustration).
5Swing the caliper rearwards and remove the
pads (see illustration). Do not press the brake
pedal with the caliper removed.
6Clean the dust and dirt from the caliper,
bracket and disc, using a damp cloth or old
paintbrush which can be thrown away
afterwards. Take care not to disperse the dust
into the air, or to inhale it, since it may contain
asbestos. Scrape any scale or rust from the
disc. Investigate any hydraulic fluid leaks.
7Retract the caliper piston, by turning it
clockwise, to accommodate the extra
thickness of the new pads. There is a Ford tool
(No 12-006) for this purpose, but a pair of
circlip pliers or any similar tool can be used
instead (see illustration).
8Remove any backing paper from the newpads, then fit them to the caliper bracket. Be
careful not to contaminate the friction surfaces
with oil or grease.
9Swing the caliper over the pads. Refit and
tighten the slide bolt.
10Reconnect the wear warning wires, if fitted.
11Repeat the operations on the other rear
caliper.
12Secure the handbrake cable, refit the wheels
and lower the vehicle. Tighten the wheel nuts.
13Switch on the ignition and pump the brake
pedal several times to bring the pads up to the
discs. Switch off the ignition and check the
operation of the handbrake.
14Avoid heavy braking as far as possible for
the first hundred miles or so to allow the new
pads to bed in.
1With the ignition off, pump the brake pedal
at least 20 times (or until it becomes hard) to
depressurise the hydraulic system.
2Slacken the front wheel nuts, raise and
support the vehicle and remove the relevant
front wheel.
3Slacken the flexible hose hydraulic union at
the caliper by no more than a quarter turn.
4Remove the brake pads (Section 7).
5The caliper can now be removed by holding
the flexible hose stationary and rotating the
caliper to unscrew it. Be prepared for hydraulic
fluid spillage: plug or cap the caliper and hose.A brake hose clamp may be used if available
(see illustration). Take great care to keep dirt
out of the hydraulic system.
6The caliper bracket may be unbolted from
the stub axle carrier if wished.
7Refit by reversing the removal operations,
but before refitting the wheel, check the
positioning of the flexible hose. It must not be
kinked, nor foul adjacent components, in any
position of the steering wheel. Release the
other end of the hose from its bracket if
necessary and reposition it.
8Bleed both front brake calipers as described
in Section 2.
1It is possible to carry out these operations
without disconnecting the caliper hydraulic
hose, but this is not recommended because of
the risk of introducing dirt into the hydraulic
system. Scrupulous cleanliness is essential.
2Obtain a caliper repair kit, which will contain
a piston seal and a dust boot. (The piston itself
can also be renewed if necessary.)
3Remove the piston from the caliper. This is
best done with low air pressure (eg from a foot
pump) applied to the hydraulic inlet union.
Place a piece of wood opposite the piston to
prevent damage, and keep your fingers clear
as the piston may be ejected with some force.
4With the piston removed, pull off the dust
boot (see illustration).

5Extract the piston seal from the groove in
the bore, using a blunt instrument (see
illustration). Discard the seal and dust boot.
6Clean the piston and bore with methylated
spirit and inspect them for scuffs, scores or
other damage. If the piston is corroded it must
be renewed. Slight imperfections in the bore
can be polished out with wire wool.
7Place the clean component on a clean
surface ready for reassembly. Lubricate the
caliper hose with clean hydraulic fluid.
8Fit the new piston seal to the groove in the
bore, using fingers only to work it into position.
9Lubricate the piston with clean hydraulic
fluid and fit the dust boot over the piston,
making sure it is the right way up. Insert the
piston into the bore and press it home,
engaging the dust boot lip with the groove on
the caliper (see illustration).
10This completes the overhaul of the hydraulic
components. Items such as slide bolts and
bracket can also be renewed if necessary.
11Remove the bleed screw while the caliper
is on the bench and apply a little anti-seize
compound to its threads, to avoid trouble in
undoing it later.
1With the ignition off, pump the brake pedal
at least 20 times (or until it becomes hard) to
depressurise the system.
2Chock the front wheels and release the
handbrake. Slacken the rear wheel nuts, raiseand support the vehicle and remove the
relevant wheel.
3Disconnect the pad wear warning wires,
when fitted.
4Disconnect the flexible hose from the brake
pipe. Plug or cap the open unions to reduce
spillage and to keep dirt out. Unscrew the
flexible hose from the caliper and remove it.
5Remove the two slide bolts. Lift the caliper
off the pads and bracket, at the same time
unhooking the handbrake cable (see
illustrations). Alternatively, the two bracket-
to-hub bolts can be removed and the caliper
and bracket separated on the bench.
6Refit by reversing the removal operations,
but before refitting the wheel, bleed both rear
calipers as described in Section 2.
7When bleeding is complete, pump the brake
pedal several times to bring the pads up to the
disc, then check the operation of the
handbrake.
Note: Complete dismantling of the rear caliper
should not be attempted unless Ford spring
compressor (tool No 12-007) is available. or
unless the problems likely to arise in the absence
of the tool are understood. Renewal of the piston
seal and dust boot requires no special tools.
1Clean the caliper externally and mount it in a
soft-jawed vice.
2Rotate the piston anti-clockwise until it isprotruding from the bore by about 20 mm (0.8 in).
Free the dust boot from the groove in the
piston, then carry on unscrewing the piston
and remove it. Remove and discard the dust
boot.
3The piston and bore may now be cleaned
and examined, and the piston seal and dust
boot renewed, as described for the front
caliper (Section 10).
4The piston adjuster nut seal should also be
renewed. Remove the circlip from the piston,
then extract the thrustwashers, wave washer
and thrust bearing. Note the fitted sequence of
these components. Finally remove the nut
(see illustrations).
5Remove the seal from the nut, noting which
way round it is fitted. Clean the nut with
methylated spirit. Lubricate the new seal with
clean hydraulic fluid and fit it to the nut.

6For further dismantling it is virtually essential
to have Ford tool 12-007. This tool appears to
be a cut-down adjuster nut with a handle for
turning it. In the workshop it was found that
the piston adjuster nut could be used to
compress the spring if it were turned with
circlip pliers (see illustration). This works well
enough for dismantling, but reassembly
proved extremely difficult because of the
limited clearance between the skirt of the nut
and the caliper bore.
7Having compressed the adjuster spring just
enough to take the load off the circlip, release
the circlip inside the caliper bore. Remove the
spring compressor, then extract the circlip,
spring cover, spring and washer (see
illustrations). 8A long thin pair of circlip pliers will now be
needed to release the key plate retaining
circlip from the caliper bore (see illustration).
With the circlip removed, the pushrod and key
plate can be pulled out.
9Remove the handbrake strut from the
caliper bore.
10Remove the handbrake lever return spring
and stop bolt. Pull the lever and shaft nut out
of the caliper. Prise out the shaft seal.
11Clean up the handbrake shaft using wire
wool; renew the shaft if it is badly corroded.
The shaft bush in the caliper can also be
renewed if necessary. Pull out the old bush
with an internal puller or slide hammer; press
in the new bush to 7.5 mm (0.30 in) below the
shaft seal lip(seeillustration).The slot in the
side of the bush must line up with the pushrod
bore in the caliper.12Having renewed components as
necessary, commence reassembly by
smearing a little brake grease or anti-seize
compound on the handbrake shaft and bush.
13Fit a new handbrake shaft seal to the
caliper. Pass the shaft through the seal and
into the caliper, being careful not to damage
the seal lips.
14Refit the handbrake lever stop bolt and
return spring.
15Refit the handbrake strut, lubricating it
with brake grease.
16Fit a new O-ring to the base of the
pushrod. Refit the pushrod and the key plate,
engaging the pip on the key plate with the
recess in the caliper. Secure the key plate with
the circlip.

17Refit the washer, spring and spring cover.
Compress the spring and refit the circlip, then
release the spring compressor.
18Lubricate the caliper bore with clean
hydraulic fluid and fit a new piston seal.
19Reassemble the piston components.
Lubricate the contact face of the adjuster nut
with a little brake grease, then fit the adjuster
nut (with new seal), thrust bearing,
thrustwasher, wave washer and the second
thrustwasher. Secure with the circlip.
20Fit a new dust boot. The manufacturers
recommend that it be fitted to the caliper
groove and the piston fitted afterwards; it is
also possible to fit the boot to the piston first
and engage it in the caliper groove afterwards.
Either way it is a fiddly business.
21Refit the piston and screw it into the
caliper, then fit whichever lip of the dust boot
was left free (see illustration).22Renew the slide pin gaiters and apply a
little anti-seize compound to the slide pins
when reassembling the caliper to the bracket.
The splash shield is retained by the rear hub
bolts. Proceed as described in Chapter 11 for
removal and refitting of the rear hub.
1Disconnect the battery negative lead.
2Depressurise the hydraulic system by
pumping the brake pedal at least 20 times, or
until it becomes hard.
3Remove the under-dash trim on the driver’s
side.
4Remove the spring clip which secures the
hydraulic unit pushrod to the brake pedal. Also
remove the clip from the brake pedal shaft
(see illustration).
5Withdraw the brake pedal shaft towards the
left of the vehicle - through the clutch pedal,
