low beam FORD FIESTA 1989 Service Repair Manual

1 General information
The braking system is of the diagonally
split, dual-circuit hydraulic type, with servo
assistance to the front disc brakes and rear
drum brakes. The dual-circuit hydraulic
system is a safety feature - in the event of a
malfunction somewhere in one of the
hydraulic circuits, the other circuit continues
to operate, providing at least some braking
effort. Under normal circumstances, both
brake circuits operate in unison, to provide
efficient braking.
The master cylinder (and the vacuum servo
unit to which it is bolted) is located on the left-
hand side of the bulkhead in the engine
compartment. On all right-hand drive variants,
they are jointly operated via a transverse
cross-link from the brake pedal.
Brake pressure control valves are fitted in-
line to each rear brake circuit, their function
being to regulate the braking force available at
each rear wheel, reducing the possibility of
the rear wheels locking up under heavy
braking. Courier models also have a “light-
laden” valve incorporated into the rear braking
circuits for the same reason. The front brake discs are of the ventilated
type on XR2i and ABS-equipped models, with
solid discs fitted on all other models. The front
brake calipers are of single sliding piston type
mounted on the front spindle carriers each
side. Each rear brake shoe assembly is operated
by a twin-piston wheel cylinder. The leading
brake shoe in each brake unit has a thicker
lining than the trailing shoe, so that they wear
proportionally. To take up the brake
adjustment as the linings wear, each rear
brake assembly incorporates an automatic
adjuster mechanism. The cable-operated handbrake acts on
both rear brakes, to provide an independent
means of brake operation. An anti-lock braking system (ABS) is
available on some models, and has many of
the components in common with the conventional braking system. Further details
on ABS can be found later in this Chapter.
Note:
When servicing any part of the system,
work carefully and methodically; also observe
scrupulous cleanliness when overhauling any
part of the hydraulic system. Always renew
components (in axle sets, where applicable) if
in doubt about their condition, and use only
genuine Ford replacement parts, or at least
those of known good quality. Note the
warnings given in “Safety first” and at relevant
points in this Chapter concerning the dangers
of asbestos dust and hydraulic fluid.
2 Front brake pads - renewal
2
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.
The front brake calipers will be of Bendix
or Teves manufacture, and if they or their
component parts require renewal, ensure
that the correct type is fitted. Dust created
by wear of the pads may contain asbestos,
which is a health hazard. Never blow it out
with compressed air, and do not 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 in Section 13 concerning
the dangers of hydraulic fluid.
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 Hold the caliper support spring with a pair
of pliers, and prise it out of its location in the
caliper housing using a screwdriver (see
illustration) .
3 Prise free the blanking plugs from the
caliper upper and lower mounting bolts.
Unscrew the bolts, then withdraw the caliper
from the anchor bracket (see illustrations).
Suitably support the caliper to avoid straining
the brake hose.

needed not to spill the fluid onto the hands -
wear suitable protective gloves. Plug or cap
the disconnected pipes and valve openings,
to prevent dirt ingress and further fluid loss.
4Unbolt the valve from its mounting bracket,
unhook the linkage from the rear axle, then
withdraw the valve (see illustration). The
intermediate bracket may be unbolted if
required.
Refitting
5 Refitting is the reverse of the removal
procedure; adjust the valve as described in
Section 22, then bleed the complete hydraulic
system as described in Section 13. Check the
operation of the brakes before taking the
vehicle out on the road.
22 Light-laden valve (Courier models) - adjustment
2
Note:To adjust the valve accurately, the
vehicle must be at a known rear axle loading -
owners who cannot determine the loading
with sufficient accuracy must have this check
made by a Ford dealer or similar expert.
1 For this operation, the vehicle must be
raised for access underneath at the rear, but
must be standing on its wheels. Suitable
ramps (or an inspection pit) will therefore be
required. If positioning the vehicle on a pair of
ramps, chock the front roadwheels.
2 Measure the distance between the inner
radius of the linkage’s hooked end and the
first shoulder (see illustration) . If the
dimension is not as specified for the axle
loading, adjustment is required.
3 To adjust the setting, slacken the locknut
on the valve linkage, move the rod until the
setting is correct, then tighten the locknut
securely (see illustration) . Check the
operation of the brakes before taking the
vehicle out on the road.
23 Anti-lock braking system (ABS) - general information
A mechanically-driven, two-channel anti-
lock braking system is available as a factory-
fitted option on certain model variants within
the Fiesta range.
The system comprises four main
components; two modulators, one for each
brake circuit, and two rear axle load-
apportioning valves, again, one for each brake
circuit. Apart from the additional hydraulic
piping, the remainder of the braking system is
the same as for conventional models. The modulators are located in the engine
compartment with one mounted on each side
of the transmission, directly above the
driveshaft inner constant velocity joints. Each
modulator contains a shaft which actuates a
flywheel by means of a ball and ramp clutch. A rubber toothed belt is used to drive the
modulator shaft from the driveshaft inner
constant velocity joint.
During driving and under normal braking
the modulator shaft and the flywheel rotate
together and at the same speed through the
engagement of a ball and ramp clutch. In this
condition hydraulic pressure from the master
cylinder passes to the modulators and then to
each brake in the conventional way. In the
event of a front wheel locking the modulator
shaft rotation will be less than that of the
flywheel and the flywheel will overrun the ball
and ramp clutch. This causes the flywheel to
slide on the modulator shaft, move inward and
operate a lever which in turn opens a dump
valve. Hydraulic pressure to the locked brake
is released via a de-boost piston allowing the
wheel to once again revolve. Fluid passed
through the dump valve is returned to the
master cylinder reservoir via the modulator
return hoses. At the same time hydraulic
pressure from the master cylinder causes a
pump piston to contact an eccentric cam on
the modulator shaft. The flywheel is then
decelerated at a controlled rate by the
flywheel friction clutch. When the speed of the
modulator shaft and flywheel are once again
equal the dump valve closes and the cycle
repeats. This complete operation takes place
many times a second until the vehicle stops or
the brakes are released. The load-apportioning valves are mounted
on a common bracket attached to the rear
body, just above the rear axle twist beam
location, and are actuated by linkages
attached to the axle beam. The valves
regulate hydraulic pressure to the rear brakes,
in accordance with vehicle load and attitude,
so that the braking force available at the rear
brakes will always be lower than that available
at the front. A belt-break warning switch is fitted to the
cover which surrounds each modulator
drivebelt. The switch contains an arm which is
in contact with the drivebelt at all times. If the
belt should break, or if the adjustment of
the belt is too slack, the arm will move out
closing the switch contacts and informing the
driver via an instrument panel warning light.

Modulator
Note: Before starting work, refer to the
warning at the beginning of Section 13
concerning the dangers of hydraulic fluid.
1 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).
2 Minimise hydraulic fluid loss by
disconnecting 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. Place a piece of plastic film over the
reservoir and seal it with an elastic band.
3 Disconnect the modulator return hoses
from the master cylinder reservoir, collecting
any fluid spillage from the hoses in a suitable
tray. The modulator return hose unions should
be disconnected by first pushing the hose
into the reservoir, then retaining the collar
against the reservoir body whilst withdrawing
the hose. Note that the hoses are colour
coded - the left-hand modulator has a black
return hose and connector, and should be
fitted to the forward section of the reservoir,
whilst the right-hand modulator has a grey
return hose and connector, and should be
fitted to the rear section of the reservoir.

cylinder reservoir filler cap, then remove the
filler cap. Note that the filler cap must not be
inverted. Place a piece of plastic film over the
reservoir and seal it with an elastic band.
2Raise 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.
3 Remove the spare wheel and its carrier for
access to the load-apportioning valves (see
illustration) .
4 Disconnect the load-apportioning valve
operating links from the rear axle twist beam,
by undoing the nuts securing them.
5 Disconnect the rigid brake pipes from the
load-apportioning valves, and fit blanking plugs
to prevent dirt ingress. Make provision for
escaping fluid as the pipes are disconnected. 6
Remove the bolts securing the valve
assembly mounting bracket to the
vehicle body, then carefully lower from the
vehicle.
7 The valves can now be individually removed
from the mounting bracket, as required, by
undoing the fixings securing them from the
other side of the bracket.
8 Refitting is the reverse sequence to
removal, adjusting the load-apportioning
valves, as described in the previous Section,
before refitting the spare wheel. When fitting a
new valve, the plastic tie must be cut off
before attempting any adjustment, and the
setting tool must be used as described in the
previous Section.
9 Bleed the brake hydraulic system in
accordance with Section 14.

1 General information
The front suspension is of independent
type, achieved by the use of MacPherson
struts (see illustration) . The struts, which
incorporate coil springs and integral shock
absorbers, are located at their upper
mountings by rubber insulators and secured
to the inner wing panels by cup seat
mountings and locknuts. The lower end of
each strut is bolted to the top of a cast spindle
carrier. The spindle carriers house non-
adjustable hub bearings as a variation of a
proven design. The lower mountings of the
spindle carriers are attached, via balljoints, to
a pressed-steel lower arm assembly. The
lower arm assembly consists of two sections.
The lower arm mounting bracket is bolted
securely to the underside of the vehicle, and
has a locating peg and unique outer fixing bolt
to ensure correct location. The A-shaped
lower arm is attached to its mounting bracket
by double vertical bushes and controls both
lateral and fore and aft movement of the front
wheels. The balljoints connecting the lower
mountings of the spindle carriers to the
lower arms are riveted to the lower arms, and
are not available as separate service items. An
anti-roll bar is fitted to high specification
models and, additionally on the XR2i, a front
suspension crossmember is fitted. On all models except Courier, the rear
suspension is semi-independent, with an
inverted V-section beam welded between
tubular trailing arms (see illustration). This
inverted V-section beam allows a limited
torsional flexibility, giving each rear wheel a
certain degree of independent movement,
whilst maintaining optimum track and wheel
camber control. This type of arrangement is
called a “twist beam” rear axle. The axle is
attached to the body by rubber void bushes,
through brackets bolted to the underside of
the vehicle. Each bracket has a conical
locating peg to ensure accurate alignment of
the axle assembly. The rear suspension struts,
which are similar to the MacPherson struts
used at the front, are mounted at their upper
ends by nut and captive bolt fixings through
the suspension turrets in the luggage
compartment. At their lower ends, the struts
are attached, close to the wheels, by bolts
passed through the trailing arms and lower
strut integral bushes. The rear wheel
hub/brake drum unit and spindle on each side
form an assembly which can be unbolted from
the axle without disturbing the hub bearings.
An anti-roll bar is fitted to the rear suspension
on certain later models.
Courier models are fitted with a modified
version of the twist beam rear axle, using
linked torsion bars as springs and to provide
anti-roll stabilisation (see illustration).
Separate shock absorbers are fitted to control
suspension movement.

6Use a screwdriver or suitable lever to prise
free the grease retainer (seal) from the hub
bore, but take care not to damage the bore
surface (see illustration) .
7 Remove the inner and outer bearing cones
from the bore of the hub (see illustration).
8 To remove the bearing cups from the hub,
drive them out using a suitable punch. Drive
each cup from its respective end by tapping it
alternately at diametrically-opposed points
(see illustration) . Do not allow the cups to tilt
in the bore, or the surfaces may become
burred and prevent the new bearings from
seating correctly as they are fitted.
9 Clean the bore and spindle thoroughly
before reassembly.
10 To reassemble, tap the new bearing cups
into position in the hub, using a piece of
tubing slightly smaller in its outside diameter
than that of the bearing cup. Ensure that the
cups are squarely inserted and abut their
respective shoulders in the hub.
11 Pack the inner bearing cone with the
specified grease, and insert it into its cup in
the hub.
12 To fit the grease retainer (seal), first
lubricate its inner lip to ease installation, then
lightly tap the seal into position using a block
of wood. Ensure that the seal is correctly
orientated.
13 Pack the outer bearing cone with the
specified grease, and fit it into position in its
cup.
14 The brake drum/hub can now be refitted
to the axle spindle. Before fitting into position,
first check that the brake surface area in
the drum is free of grease and oil. Locate the
drum/hub into position, then fit the retaining
nut. Tighten it to the specified torque setting
whilst simultaneously rotating the assembly to
ensure that the bearings are correctly seated.
15 Carefully tap the new hub grease cap into
position in a progressive manner around its
outer edge until it is fully fitted.
16 Refit the rubber blanking plug to the brake
backplate, and firmly apply the footbrake a
few times to take up the brake adjustment.
Check that the rear brakes do not bind when
the brakes are released. Refit the roadwheel,
lower the vehicle and then tighten the
retaining nuts to the specified torque setting.10 Rear strut (all models except Courier) - removal and
refitting

Removal
1 Chock the front wheels then jack up the
rear of the car and support it on axle stands
(see “Jacking and Vehicle Support” ).
2 On ABS-equipped models, unscrew the
retaining nuts and detach the load-
apportioning valve connecting links from the
axle beam.
3 Support the relevant trailing arm of the axle
assembly and unscrew and remove the
securing bolt from the strut-to-axle mounting
(see illustration) .
4 Prise free the protective cap from the top of
the strut mounting, located in the luggage
compartment (see illustration) .
5 Unscrew and remove the two retaining nuts
to detach the strut from its upper mounting.
Do not unscrew the central upper mounting
bolt.
6 Lower the trailing arm slightly to allow the
lower suspension strut mounting to clear its
axle location, and withdraw the suspension
strut from the vehicle.
Refitting
7 Refitting is a reversal of the removal
procedure, but note the following special
points: a)
With the suspension strut located to its
upper mounting, tighten the retaining nuts
to the specified torque.
b) When reconnecting the suspension strut
to the lower mounting, hand-tighten the
retaining bolt, then lower the vehicle so
that it is standing on its wheels before
fully tightening the bolt to its specified
torque.

a suitable tool to hold the coil
spring in compression must be
obtained. Adjustable coil spring
compressors which can be positively
secured to the spring coils are readily
available, and are recommended for this
operation. Any attempt to dismantle the
strut without such a tool is likely to result
in damage or personal injury.
Dismantling
1 With the strut removed from the vehicle,
clean away all external dirt, then secure it in a
vice.
2 Fit the spring compressor tool (ensuring
that it is fully engaged) and compress the coil
spring until all tension is relieved from the
upper mounting.

3Unscrew and remove the upper mounting
through-bolt and nut.
4 Withdraw the upper mounting cup and the
spring seat.
5 The suspension strut and coil spring can now
be separated. If the coil spring or strut is to be
renewed, the original coil spring must be
released from the compressor. If it is to be re-
used, the coil spring can be left in compression.
Examination
6 With the strut assembly now completely
dismantled, examine the mounting
components for wear, damage or deformation.
Renew any of the components as necessary.
7 Examine the strut for signs of fluid leakage.
Check the strut piston for signs of pitting
along its entire length, and check the strut
body for signs of damage or deterioration of
the mountings. Test the operation of the strut,
holding it in an upright position, by moving the
piston through a full stroke, and then through
short strokes of 50 to 100 mm. In both cases,
the resistance felt should be smooth and
continuous. If the resistance is jerky, or
uneven, or if there is any visible sign of wear
or damage to the strut, renewal is necessary.
Reassembly
8 Reassembly is a reversal of the dismantling
procedure but note the following points: a) When the spring is located over the
suspension strut, the spring seat, cup and
through-bolt fitted, tighten the retaining
bolt to the specified torque.
b) When reassembled, check that the upper
and lower spring tails are correctly
engaged with their spring seats before
removing the spring compressor.
12 Rear axle (all models except
Courier) -
removal and refitting
3
Removal
1 Chock the front wheels then jack up the
rear of the car and support it on axle stands
(see “Jacking and Vehicle Support” ). Remove
the rear roadwheels.
2 Refer to Chapter 9 for details, and disconnect
the handbrake cable equaliser from the primary
cable. Remove the handbrake rear cable from
its adjuster and its fixed body locations.
3 Disconnect the rear brake flexible hydraulic
brake hoses from their rigid line connections.
Clamp the hoses before disconnecting them,
to minimise the fluid loss and air entry into the
hydraulic system (see Chapter 9 for details).
4 On ABS-equipped models, undo the
retaining nuts and detach the ABS load-
apportioning valve operating links from the
axle beam. Do not remove the load-
apportioning valve (see Chapter 9).
5 Locate suitable jacks or axle stands under
the axle beam to support its weight (not to lift
it), then unscrew the four mounting bracket
bolts each side. 6
Unscrew and remove the strut-to-axle
mounting bolt each side.
7 Check that all associated fittings are clear,
then lower the axle and remove it from under
the vehicle.
8 If the twist beam axle has been damaged, it
must be renewed. Refer to Chapter 9 for
details on removing the rear brakes from the
axle. To remove the front mounting/pivot
brackets from the axle, unscrew the pivot bolt.
Refitting
9 Refitting is a reversal of the removal
procedure, but note the following: a) Reconnect the axle at the front floor mountings first, and tighten the retaining
bolts to the specified torque.
b) Reconnect the axle to the suspension struts, but do not fully retighten the securing
bolts until after the vehicle is lowered to the
ground and is standing on its wheels.
c) Ensure that all brake fluid line connections are clean before reconnecting them. Refer
to the appropriate Sections in Chapter 9
for specific details on reconnecting the
brake lines, bleeding the brake hydraulic
system, and for reconnecting the
handbrake cable and its adjustment.
d) When the vehicle is lowered and is standing
on its wheels, tighten the suspension
fastenings to their specified torque settings.
13 Rear axle pivot bushes (all
models except Courier) -
renewal
3
Note: Two different types of pivot bushes
have been fitted during the course of Fiesta
production. It is understood that once stocks
of the early type are exhausted, only the latter
type will be supplied by Ford parts dealers. If
renewing pivot bushes on a pre-April 1990
model, and only the later type bushes are
available, fit the new bushes as described
from paragraph 15 onward.
Pre-April 1990 models
1 Chock the front wheels then jack up the
rear of the car and support it on axle stands
(see “Jacking and Vehicle Support” ).2
Position a suitable support (preferably
adjustable) under the axle twist beam so that
it is capable of carrying the weight of the axle
(not the weight of the vehicle).
3 On ABS-equipped models, undo the
retaining nuts and detach the ABS load-
apportioning valve operating links from the
axle beam. Do not remove the load-
apportioning valve (see Chapter 9).
4 Unscrew the nuts, withdraw the pivot bolts,
then lower the rear axle so that the bushes are
clear of their mounting brackets (see
illustration) . Take care not to allow the brake
pipes to become distorted and stretched - if
necessary, disconnect the hydraulic lines (see
Chapter 9 for details).
5 Undo the four body mounting bracket bolts
and remove the brackets.
6 Using a soft-faced hammer and a suitable
punch or drift, drive the bushes from their
locations, taking care not to raise any burrs on
the trailing arm eyes.
7 To fit the new bushes, obtain a steel tube of
a diameter slightly less than that of the bush
location in the axle, various flat washers and a
long bolt and nut.
8 Place the new bush in position in its axle
location with the bush collar nearest to the
outer edge of the vehicle. The bush must be
installed with its voids positioned as shown
(see illustration) . Using the steel tube,
washers, long bolt and nut, draw the bush
inwards towards the centre of the vehicle (see
illustration) . Care should be taken to avoid
damage to the bush and to obtain correct

positioning of the voids. Install the bush on
the other side in the same way.
9With the new bushes in position, refit the
body mounting brackets loosely to the trailing
arms - do not fully tighten the pivot bolts at
this stage. Final tightening is carried out with
the vehicle standing on its roadwheels.
10 Raise the axle assembly so that the
conical locating pegs on the body mounting
brackets engage in their body locations. Refit
the body mounting bracket bolts and tighten
to the specified torque.
11 On ABS equipped models, reconnect the
load-apportioning valve operating links to the
rear axle beam
12 If the flexible brake hoses were
disconnected during this operation, reconnect
them and bleed the brake hydraulic system
(see Chapter 9).
13 Lower the vehicle to the ground.
14 Fully tighten the bush pivot bolt nuts to
the specified torque.
April 1990 models onward
15 As mentioned in the note at the start of
this Section, all later models are fitted with
revised bushes which use 12 mm (thread size)
pivot bolts. If the later type bushes are to be
fitted to a pre-April 1990 model, two
corresponding bolts and nuts must be
obtained at the same time, and either the
body mounting brackets must be replaced by
the corresponding modified items, or the
holes in the original brackets must be opened
out (to 12.5 mm) to suit the new bolts.
16 Carry out the operations described in
paragraphs 1 to 4 above.
17 Using a steel tube of suitable diameter,
various flat washers and a long bolt and nut,
draw the bush out of its location in the axle
trailing arm.
18 Clean the bush eye in the trailing arm;
lubricate it, and the new bush, with a soapy
solution (washing-up liquid, for example) prior
to installation.
19 Locate the new bush in position, together
with the steel tube, washers, bolt and nut as
used for removal. Ensure that the bush flange
is positioned on the outside, then draw the
bush fully into position so that its lip is
engaged (see illustration) .
20 Raise the axle to reposition the bush pin bores in line with the bolt holes in the
mounting brackets, then insert the pivot bolts.
Screw the retaining nuts into position on the
pivot bolts, but do not fully tighten them at
this stage.
21
Carry out the operations described in
paragraphs 11 to 14 above.
14 Rear suspension anti-roll bar (all models except Courier) -
removal and refitting
2
Removal
1 Chock the front wheels then jack up the
rear of the car and support it on axle stands
(see “Jacking and Vehicle Support” ).
2 Undo the front clamp bolt from each end of
the bar, then support the bar and undo the
rear bolt at each end; withdraw the bar (see
illustration) .
3 Prise open the clamps to release the rubber
bushes, if required. Fit the new bushes using
soapy water as a lubricant.
Refitting
4 On refitting, offer up the bar and align first
the front clamp on each side, refitting the
bolts loosely.
5 Align and refit the rear clamp on each side;
again, tighten the bolts only loosely. 6
Lower the vehicle to the ground, rock it to
settle the suspension, then tighten the clamp
bolts to the specified torque settings.
15 Rear suspension components (Courier
models) - general
Although it is possible to remove the rear
suspension torsion bars and stabiliser bar
independently of the complete rear axle
assembly, it is essential to have certain
special tools available to complete the work
successfully.
Due to the complexity of the tasks, and the
requirement for special tools to accurately set
the suspension geometry and vehicle ride
height on refitting, the removal and refitting of
individual rear suspension components is
considered to be beyond the scope of DIY
work and should be entrusted to a Ford
dealer. Procedures for removal and refitting of the
rear shock absorbers, and the complete rear
suspension assembly are given in Sections 16
and 17 respectively.
16 Rear shock absorber (Courier models) - removal,
examination and refitting
