15A long thin pair of circlip pliers will now be
required 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.
16Remove the handbrake strut from the
caliper bore.
17Remove the handbrake lever return spring
and stop bolt. Pull the lever and shaft nut out
of the caliper. Prise out the shaft seal (see
illustration).
18Clean 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, and
press in the new bush to 7.5 mm (0.30 in)
below the shaft seal lip (see illustration). The
slot in the side of the bush must line up with
the pushrod bore in the caliper.19Having renewed components as
necessary, commence reassembly by
smearing a little brake grease or anti-seize
compound on the handbrake shaft and bush.
20Fit a new handbrake shaft seal to the
caliper. Pass the shaft through the seal and
into the caliper, taking care not to damage the
seal lips.
21Refit the handbrake lever stop bolt and
return spring.
22Refit the handbrake strut, lubricating it
with brake grease.
23Fit 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.
24Refit the washer, spring and spring cover.
Compress the spring and refit the circlip, then
release the spring compressor.
25Lubricate the caliper bore with clean
hydraulic fluid and fit a new piston seal.
26Reassemble 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.
27Fit a new dust-excluding seal to the
grooves in the piston and caliper bore as the
piston is refitted (see illustration). Screw the
piston into the caliper bore with the tool used
during removal.
28Renew the guide pin gaiters and apply a
little brake grease or anti-seize compound to
the guide pins when refitting the caliper to its
carrier bracket.
Refitting
29Refitting is a reversal of removal, but on
completion bleed the rear brake circuit and
check the operation of the handbrake.
Note: From 1987, thicker brake discs were
fitted. If the later discs are fitted to earlier
models, longer wheel studs must be fitted to
accommodate the increased thickness.
Consult a dealer for further advice.
Front disc
1Apply the handbrake, loosen the relevant
roadwheel nuts, then jack up the front of the
vehicle and support on axle stands (see
“Jacking and Vehicle Support”). Remove the
roadwheel.
2Remove the disc caliper and carrier bracket
but do not disconnect the flexible hose.
Support the caliper on an axle stand to avoid
straining the flexible hose.
3Rotate the disc and examine it for deep
scoring or grooving. Light scoring is normal,
but if excessive, the disc should be removed
and either renewed or reground by a suitable
specialist. Scrape any corrosion from the disc.

relation to the drive flange and on Saloon,
Hatchback and Estate models, remove the
retaining screw or spire washer(s), as
applicable, and remove the disc. On P100
models, also mark the position of the wheel
adapter plate in relation to the disc and drive
flange, then unscrew the five retaining nuts
and remove the wheel adapter plate and disc.
6Refitting is a reversal of removal, but when
refitting ensure that the mating faces of the
disc, drive flange and on P100 models the
wheel adapter plate, are clean. Align the
marks made on the disc, drive flange, and
where applicable the wheel adapter plate,
during removal. Refit the disc caliper and
carrier bracket.

disc.
12Refitting is a reversal of removal, but
ensure that the mating faces of the disc and
drive flanges are clean, and align the marks
made on the disc and drive flange during
removal.
1Whenever a brake drum is removed, brush
out the dust, taking care not to inhale any, as
it may be injurious to health.
2Examine the internal friction surface of the
drum. If deeply scored, or so worn that the
drum has become ridged to the width of the
shoes, then both drums must be renewed.
3Regrinding is not recommended as the
internal diameter of the drum will no longer be
compatible with the shoe friction material
contact diameter.
Saloon, Hatchback and Estate
models
1Chock the front wheels, loosen the relevant
roadwheel nuts, then jack up the rear of the
vehicle and support on axle stands (see
“Jacking and Vehicle Support”).Remove the
roadwheel and release the handbrake.
2Remove the retaining spire washer(s) from
the wheel stud(s) and pull off the brake drum.
If the drum will not pass over the shoes, it is
possible to release the automatic adjuster
mechanism by inserting a screwdriver through
the small hole in the drum and pressing down
on the ratchet.
3Remove the brake fluid reservoir cap and
secure a piece of polythene over the filler
neck with a rubber band, or by refitting the
cap. This will reduce the loss of fluid during
the following procedure.
4Unscrew the union nut and disconnect the
fluid pipe from the wheel cylinder (see
illustration). Plug the open ends of the pipe
and wheel cylinder to prevent fluid loss and
dirt ingress.
5Pull the tops of the brake shoes apart so
that the self-adjuster mechanism holds them
clear of the wheel cylinder.
6Unscrew the two retaining bolts from the
rear of the brake backplate, and withdraw the
wheel cylinder and sealing ring.
7The wheel cylinder can now be dismantled
as follows.
8Prise the dust-excluding rubber seals from
the ends of the wheel cylinder, and withdraw
the pistons and central spring, identifying the
pistons so that they can be refitted in their
original positions.
9Prise the seals from the pistons.
10Clean all the components in methylated
spirit and allow to dry. Examine the surfaces
of the pistons and cylinder bore for wear,
scoring and corrosion. If evident, the
complete wheel cylinder must be renewed,
but if the components are in good condition,
discard the seals and obtain a repair kit.
11Dip the new seals in clean brake fluid and
fit them to the piston grooves, using fingers
only to manipulate them. Ensure that the seal
lips face into the wheel cylinder.
12Carefully insert the pistons and central
spring into the cylinder, and fit the
dust-excluding rubber seals. Ensure that the
pistons are fitted in their original positions.
13Wipe the brake backplate clean, then fit
the wheel cylinder together with a new sealing
ring, and tighten the securing bolts.14Reconnect the fluid pipe to the wheel
cylinder and tighten the union nut.
15Using a screwdriver, push the
self-adjuster toothed quadrant fully towards
the backplate to its initial setting.
16Further refitting is a reversal of removal,
but on completion apply the footbrake several
times in order to set the brake shoes in their
normal positions, and bleed the rear brake
circuit.
P100 models
17The procedure is as described in
paragraphs 1 to 16 inclusive, but with the
following differences.
18Before removing the roadwheel, mark its
position in relation to the brake drum.
Similarly, mark the position of the brake drum
in relation to one of the wheel studs. Align the

Ford spec SPM-4G-9112-F, then refit the
baffle and the backplate to the axle, tightening
the six securing nuts to the specified torque.
16Use a new rear hub nut, and tighten to the
specified torque. Stake the nut into the groove
in the axle tube after tightening.
17Refit the driveshaft, using a new O-ring.
Note: A suitable puller will be required to
remove the drive flange, and a new rear hub
nut must be used on reassembly.
Removal
1Loosen the rear hub nut with the vehicle
resting on its wheels. Note that the left-hand
nut has a left-hand thread, ie it is undone in a
clockwise direction. Before loosening the nut,
ensure that the handbrake is applied, and
chock the relevant rear wheel. A suitable
extension bar will be required, as the nut is
extremely tight.
2Loosen the relevant rear roadwheel nuts,
chock the front wheels, then jack up the rear
of the vehicle and support on axle stands (see
“Jacking and Vehicle Support”).Remove the
roadwheel and release the handbrake.

excessive angles, and do not allow the shaft
to hang down from one end.
Refitting
8Refitting is a reversal of removal, bearing in
mind the following points.
9When reassembling the drive flange and the
hub carrier, fit the drive flange to the hub
carrier in order to centralise the bearings, then
using a soft-faced mallet, drive the drive
flange/hub carrier assembly onto the end of
the stub axle.10Refit the hub carrier/splash
shield-to-lower arm securing bolts. Note that
there are two types of bolts used to secure
the rear hub carrier to the lower arm. The two
types of bolt must not be mixed on a vehicle
but can be changed in complete sets for the
alternative type. A complete set is eight bolts,
four each side. Note that the two types of bolt
have different torque wrench settings. When
renewing the wheel bearings a suitable puller
will be required to remove the drive flange,
and a new rear hub nut must be used on
reassembly.
11When refitting the brake disc, align the
previously made marks on disc and drive
flange.
12Fit a new rear hub nut of the correct type,
and tighten it with the vehicle resting on its

11Ensure that both handbrake operating
levers are returned to their stops on the
calipers, then make alignment marks between
the levers and the caliper bodies (see
illustration).
12Turn the adjuster until either lever just
starts to move, as indicated by the alignment
marks.
13Apply the handbrake and release it
several times to equalise the cable runs.
14With the handbrake released, proceed as
described in paragraphs 6 and 7.
15Refit the cables to the lower suspension
arms, and secure by bending over the tangs.
16Check that with the handbrake released,
the rear wheels are free to rotate and no brake“bind” is evident. The handbrake lever travel
should be between two and four clicks of the
ratchet. If brake “bind” or excessive lever
travel is evident, check the handbrake cable
routing, and check the caliper mechanism for
wear or damage.
