30A-5
GENERAL INFORMATION
Braking circuit: Bleed
30A
a Connect the brake circuit bleeding device (after
having received Renault approval) to the master cyl-
inder reservoir (see the instructions for the equip-
ment).
a Pressurise the brake circuit.
a Adjust the pressure to between 1.5 bar < P < 2 bar
for 3 minutes to stabilise it in the braking circuit.
a Close the circuit between the bleed screw and brake
fluid reservoir without dumping the pressure.
a Fit the bleed containers to the four bleed screws of
the callipers.
a Undo the calliper bleed screws:
-front left-hand,
-front right-hand,
-rear left-hand,
-rear right-hand.
a Open the circuit between the bleed screw and brake
fluid reservoir and allow the liquid to run until all the
air bubbles have been released.
a Tighten the bleed screws in the following order:
-front left-hand,
-front right-hand,
-rear left-hand,
-rear right-hand.
a Undo the calliper bleed screw:
-front left-hand,
-allow the fluid to run until all the air bubbles have
been released,
-tighten the bleed screw on the calliper.
a Carry out the previous operation on the callipers:
-front right-hand,
-rear left-hand,
-rear right-hand.
a Close the bleed screw to dump the pressure in the
brake circuit.
a Remove the brake circuit bleeding device from
the master cylinder reservoir.
a Check pedal travel and resistance. If it is not correct,
finish bleeding the brake circuit with the help of a se-
cond operator. Start the bleed operation by bleeding
the calliper that is the furthest away from the master
cylinder:
- hold down the brake pedal,
- open the circuit bleed screw to release the air from
the brake circuit,
- close the circuit bleed screw,
- release the brake pedal.
a Top up the brake fluid level in the reservoir, if neces-
sary. Check the sealing of the front and rear bleed
screws and ensure that the sealing covers are in
place (see 30A, General information, Brake cir-
cuit: Tightening torque, page 30A-6) .
a During a road test, trigger braking regulation to con-
firm that the brake pedal travel is correct.
a Clean off any traces of brake fluid on the vehicle us-
ing BRAKE CLEANING PRODUCT (see Vehicle:
Parts and consumables for the repair)
Note:
The circuit between the bleed screw and brake
fluid reservoir is closed in different ways depen-
ding on the type of equipment used:
-valve,
-switch.
