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.

2)Bleeding the hydraulic assembly.
IMPORTANT : the bleeding order must be observed, beginning with the rear right , then the rear left, front
left and then front right.
a)Bleed the rear right brake by bleeding the hydraulic assembly secondary circuit using the XR25:
- position the bleed container and the hose, open the brake bleed screw,
- pump the brake pedal (approximately ten times),
- start the bleed command on the
XR25,
- pump the brake pedal during the diagnostic bleed phase,
- at the end of the bleed cycle on the
XR25, continue to pump the brake pedal and close the brake
bleed screw.
b)Carry out the procedure described at a) for the rear left, front left and front right brakes.
c)Check the pedal travel and if it is incorrect, restart the bleeding procedure.
IMPORTANT : ensure there is sufficient brake fluid in the reservoir.
CHECKING THE WHEEL SPEED SENSORS
a)Check the resistance of the sensor connections (from the computer connector to the 2 track speed sensor
connector).
b)Visually inspect the teeth ( 26 teeth) on the target and if they are faulty, replace the target.
c)Check the air gap using a set of shims. Only the front sensors can be checked.
