TIGHTENING TORQUES (in daN.m)
REMOVAL
Put the vehicle on a two post lift.
Remove both wheels.
Remove the mounting nuts for the anti-roll bar on
the lower wishbones.
Release the anti-roll bar downwards.
Remove:
- the nut and key on the stub-axle carrier,
- the two mounting bolts for the wishbone on
the sub-frame,
- the wishbone.
REFITTING
NOTE :
ensure the plastic protective washer ( A ) is
present on the lower ball joint shaft.
Refit:
- the wishbone,
- the two bolts, without tightening them,
- the ball joint shaft in the stub-axle carrier and
tighten the key nut.
Refit the anti-roll bar and fit the mounting nuts
using tool Sus. 1414 (see method in anti-roll bar
section).
This tool allows the rubber mounting to be
compressed to fit the nut.
NOTE : bounce the suspension and tighten the
wishbone and anti-roll bar bearing nuts to the re-
commended torque (tightening position: vehicle
unladen).

REMOVAL
Disconnect the wear warning light wire (if fitted).
Push the piston back, sliding the caliper by hand.
Remove the lower brake caliper guide bolt.
SPECIAL TOOLING REQUIRED
Fre. 823 Tool for pushing piston back
Wheel bolts 9
Brake caliper guide bolt 4
12994R
REFITTING
Push back the caliper piston using tool Fre. 823.
Fit new brake pads.
The brake pad with the wear warning light wire
(if fitted) is fitted to the inside.
Refit the caliper into position and fit the lower
guide bolt.
Tighten the guide bolt to the recommended
torque 4 daN.m.
Reconnect the wear warning light wire (if fitted).
Press the brake pedal several times to bring the
piston into contact with the pads.
TIGHTENING TORQUES (in daN.m)
Pivot the caliper around the upper bolt.
Remove the brake pads.
Check:
- the condition and mounting of the piston dust
cover,
- the condition of the guide dust cover.

REPAIR
NOTE :
if there are any scratches in the caliper
bore, the complete caliper must be replaced.
To do this:
- remove the brake caliper,
- remove the rubber dust cover,
- remove the piston using compressed air,
inserting a wooden block between the caliper
and the piston to prevent damage to the
piston: any trace of damage to the piston skirt
will render it unusable
- remove the seal from the caliper groove using
a flexible rounded edge blade (eg feeler
gauge).
Clean the parts using methylated spirits.
Replace any faulty parts using original parts and
then refit the seal, piston and dust seal.
REMOVAL
In the passenger compartment, fit a pedal press
(limits the amount of brake fluid which will run
out).
Release the brake pipe at the wheel cylinder end.
Remove the brake pads (see previous page).
Remove the two mounting bolts for the caliper on
the stub axle carrier.
Completely release the brake pipe by turning the
caliper.
Check the condition of the pipe and replace it if
necessary.
REFITTING
Fit the pipe onto the caliper.
Remove the pedal press.
To check the correct operation of the caliper
cylinder, slacken the bleed screw and wait for
brake fluid to run out.
Retighten the bleed screw.
Refit the caliper on the stub axle carrier and
tighten the bolts to the recommended torque.
Refit the pads and the wheel cylinder (follow the
method described previously).

Brake discs
31
Brake discs cannot be reground. If they are too
heavily worn or are scratched they must be repla-
ced.
Wheel bolts 9
Brake caliper mounting bolt 10
REMOVAL
Remove:
- the two brake assembly mounting bolts
(attach the assembly to the spring),
- the two mounting bolts securing the disc to
the hub,
- the disc.
REFITTING
Refitting is the reverse of removal.
NOTE : when a brake disc is replaced, the pads
must also be renewed.

REMOVAL
Disconnect the battery.
Remove:
- the wheel,
- the brake caliper and attach it to the spring so
the pipe is not damaged,
- the track rod end using tool
T.Av. 476,
- the driveshaft nut.
Push back the driveshaft using tool :
T. Av. 1050-02.
Remove:
- the brake disc,
- the lower ball joint nut and key,
- the two shock absorber base bolts,
- the hub / stub axle carrier / bearing assembly.
TIGHTENING TORQUES (in daN.m)Remove the hub on the press.
Remove the lower bush from the hub using an ex-
tractor with jaws and tool Rou. 15-01.
Remove the locking spring ring from the stub axle
carrier.
On the press remove the remainder of the bea-
ring, taking care to take the weight on the inner
bush using a tube of the same diameter.

REMOVAL
Put the vehicle on a four post lift.
Remove:
- the wheels,
- the shock absorber base mounting bolts.
NOTE : release the ABS sensor wiring if this is
fitted on the base of the shock absorber.
Remove the upper shock absorber nut in the
engine compartment.
Remove the shock absorber and spring assembly.

EQUIPMENT REQUIRED
Replacing a shock absorber
When replacing a shock absorber, fit it in a vice
and compress the spring using the spring
compressor tool.
Remove the spring retaining nut.
Remove the spring and the intermediate parts.
If necessary, replace the shock absorber pad and
the rotating stop.
When refitting, ensure all components are
replaced in the correct location and then
decompress the spring.
NOTE : apply grease between the ends of the
spring and its stops.
REFITTING
Refitting is then the reverse of removal. Observe
the correct tightening torques.

reach the upper bolt on the sub-frame - side mem-
ber tie rod and remove it.
Remove:
- the exhaust downpipe and attach the catalytic
converter,
- the bolt (engine side) for the engine tie bar.
- the gear control by removing the two bolts at
the ends of the control. To do this, the cataly-
tic converter heat shield must be removed and
