Brake fluid

GENERAL
Brake unions and pipes
30
The connection of the pipes between the master
cylinder, calipers, compensator and the hydraulic
assembly is made using threaded unions with a
METRIC THREAD.
Consequently, only parts specified in the Parts
Catalogue for this vehicle should be used.
Identification of parts
- SHAPE of the ends of PIPES in steel or copper
(A),
- SHAPE of the THREADED LOCATIONS on
components (B),
- pipe UNIONS coloured GREEN or BLACK:
HEXAGONAL OUTSIDE 11 mm or 12 mm (C).
BRAKE FLUID RENEWAL FREQUENCY
Braking technology, in particular for disc brakes (hollow pistons which transmit little heat, low volume of
fluid in the cylinder, sliding calipers avoiding the need for a fluid reservoir in the least cooled area of the
wheel), has allowed us to avoid the risk of vapour lock as far as possible, even if the brakes are used
intensively (in mountainous areas).
Modern brake fluids still degrade slightly during the first few months of use due to a small uptake of
humidity and replacement of the fluid is therefore recommended (refer to vehicle’s Warranty and Servicing
Handbook).
Topping up the level:
Wear of the brake pads and shoes will cause a gradual drop in the fluid level in the reservoir. This drop should
not be compensated for since the level will rise again when the pads are changed. The level should not
however be allowed to fall below the minimum mark.
Approved brake fluids:
Mixing two incompatible brake fluids in the circuit will cause a risk of major leaks, mainly due to
deterioration of the cups. To avoid such risks, it is important to use only those brake fluids which have been
tested and approved by our Technical Department and which conform to standard SAE J 1703 dot 4.

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).

FRONT AXLE
Lower wishbone rubber bushes
31
90404R
REPLACEMENT
To ensure the bushes are correctly positioned in
relation to the lower wishbone, they are replaced
one after the other.
On the press, remove one of the worn bushes
using a tube of external diameter 30 mm.
Refit the new bush, ensuring that dimension A =
146.5 mm.
Remove the second bush on the press and proceed
in the same manner as for the first bush, ensuring
the new bush is fitted so that dimension A =
146.5 mm.
31-2

FRONT AXLE
Lower wishbone ball joint
31
85875R1
Remove:
- the two ball joint mounting bolts (4) ,
- the ball joint.
REFITTING
Note : ensure the plastic protective washer ( A ) is
present on the lower ball joint shaft.
Fit the ball joint and torque tighten the
mountings.
Then proceed in the same manner as for refitting
the lower wishbone.
REMOVAL
If the gaiter is damaged, the complete ball joint
must be replaced.
Proceed in the same manner as for removing the
lower wishbone.
Slacken but do not remove the two mounting
bolts (3) for the wishbone on the sub-frame.

FRONT AXLE
Brake pads
31
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.

Front brake calipers
31
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).
