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.

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.

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.
