REMOVAL
Brake shoes must be replaced on the complete
axle - never fit shoes of differing makes or
grades.
Remove:
- the brake drum (see corresponding paragraph),
- the lower spring (2) using brake shoe pliers.
Using adjustable pliers, remove the shoe side
retaining springs.
In turn, pass each brake shoe base over the fixed
point. Squeeze the bases of the shoes together to
separate the ends at the wheel cylinder end.
Separate the assembly (RAI and shoes) from the
brake backing plate then remove it, after
unclipping the handbrake cable.

REFITTING
Present the assembly to the vehicle.
Attach the handbrake cable to the lever.
Squeeze the bases of the shoes together and
position the other ends on the wheel cylinder
pistons. Take care not to damage the covers.
Position the shoes on the fixed point (C).
Fit the side retainers (3).
Remove the pliers from the wheel cylinder pistons
then refit the lower spring (2).
ADJUSTMENT
Using a screwdriver, adjust the brake shoe
diameter using the notched segment.
Refit the drums without tightening the nuts.
Centre the linings by repeatedly pressing the
brake pedal (approximately 20 times).
Ensure the RAI is operating correctly
(characteristic click from the drums).
Remove the drums.
Ensure:
- the cables slide freely,
- the handbrake levers (L) are correctly
positioned against the shoes.
Progressively tighten the cables at the central
adjustor so that levers (L) start to move between
the 1st and 2nd notch of the control lever travel
and remain applied from the 2nd notch.
Lock the lock nut on the central adjuster.
Refit:
- the drums and tighten the nuts to a torque of
17.5 daN.m,
- the plugs.

touches the shoulder.
Fit:
-a new clip,
- the drum on the pre-lubricated stub axle,
-a new lock nut and tighten to the correct
torque,
- the hub plug.
Adjust:
- the brake shoes by repeatedly pressing the
brake pedal,
- the handbrake (see section 37 "Controls").

REAR AXLE
Shock absorber
REMOVAL
With the vehicle on its wheels, remove the lower
mounting bolt (1).
Lift the vehicle and remove:
- the wheel,
- the upper mounting bolt (2),
- the shock absorber.
PRECAUTIONS TO BE TAKEN BEFORE FITTING
Shock absorbers are stored horizontally in the
Parts Stores.
Under these conditions it is possible that the shock
absorbers, which are designed to operate in a ver-
tical direction, will have de-primed.
Before fitting the shock absorbers to the vehicle
compress them a few times by hand in the vertical
position.
REFITTING
Fit:
- the shock absorber,
- the upper mounting bolt coated with
MOLYKOTE BR2, without tightening it,
- the wheel.
Lower the vehicle.
Position the lower mounting bolt coated with
MOLYKOTE BR2.
Torque tighten both bolts.

Put the vehicle on a lift with the wheels hanging
free.

Remove the bar.
REFITTING
On each side, refit the bolts (1) with the captive
nuts.
Tighten to the recommended torque.

REAR AXLE
Half suspension arms, tubular rear axle
REFITTING
Ensure the bearing races or the needle bearings
are in perfect condition, otherwise replace them
(see section "Bushes, tubular rear axle").
The needle bearings are greased for life and do
not require further lubrication.
NOTE : new suspension arms are supplied by the
Parts Department fitted with bearing races or
needle bearings (depending on side).
Fit the two half suspension arms together until
dimension (B) is obtained.
NOTE : dimension (B) corresponds to the distance
between the same two mounting points for the
anti-roll bar on the suspension arms. It is therefore
possible to obtain this dimension by positioning
the anti-roll bar in its location and checking the
mounting bolts can be correctly positioned.
Ensure the fitting direction is observed.
Refitting is then the reverse of removal.
NOTE : if the half suspension arm is renewed,
bond the brake backing plate mounting bolts
with
Loctite FRENBLOC.
Bleed the brake circuit.
Adjust the handbrake control (see section 37).

REMOVAL
Put the vehicle on a two post lift, remove:
- the anti-roll bar,
- the lower shock absorber mounting,
- the secondary handbrake cable, disconnecting
at the central adjuster under the vehicle,
- the brake pipe,
- the two bearing mounting nuts (A).
Slacken the two nuts (A) on the other bearing so
the half suspension arm can be released from its
mountings.
Remove the half suspension arm, separating one
from the other.

Grind the bearing races on the male suspension
arm (right hand side) using a straight grinding
wheel, taking care not to mark the tube.

SPECIAL TOOLING REQUIRED
T. Ar. 960-02 Bush + spacer extractor
T. Ar. 960-05 Tooling for replacing needle
bearings.
REMOVAL
Remove from the female suspension arm (left
hand side) :
- the outer bush (6) using tool T.Ar. 960,
- the inner bush (7) using the small socket of
tool T.Ar. 960.
This operation is carried out after removing the complete rear axle assembly and separating the two
suspension arms.

Split the bearing races using a chisel then remove
them.
Cut and remove the seal (5).

Tool T.Ar. 960-05 must be used for fitting the
needle bearings and the bearing races.
Fit :
- the small needle bearing on the mandrel (A),
- the mandrel (A) into the tube, using mandrel
(B) as a guide.

On the press, press on until mandrel (B) touches
the tube.
Remove mandrels (B) and (A).
Fit the new seal (5) on the male tube.
The bearing races have an input chamfer on one
side.
It is important to observe the fitting direction:
chamfer (4) must be aligned as shown in the
diagram to ensure sufficient bearing surface to
press the parts on.
Fit:
- the large bearing race in sleeve (D),
- the assembly of sleeve (D) and (C) on the
tube.

Press on the assembly (D) and (C) until the sleeve
(C) reaches the edge (3) of the tube.
Fit :
- the small bearing race in sleeve (C),
- sleeve (C) on the tube, using sleeve (D) as a
guide.
On the press, press on until the sleeve (C) reaches
the edge (3) of the tube.
Remove sleeves (C) and (D).
IMPORTANT
When pressing on the parts, if the weight has
been taken on the axle mounting bearings, it
must be ensured that the suspension arms are
correctly located in their mountings (risk that
they may have been moved).
Recentre them if necessary.
Assemble the two half axle sections.
NOTE : the needle bearings are greased for life
and do not require further lubrication.
Reconnect and refit the rear axle assembly to the
vehicle (see corresponding section).
