GENERAL INFORMATION
Brake circuit: Precautions for the repair
30A
I - SAFETY
1 - Advice to be followed before any operation
For an operation requiring the use of a lift, follow the
safety advice (see Vehicle: Towing and lifting) (02A,
Lifting equipment).
The brake regulation circuit must be free of all hydrau-
lic and electrical faults.
In case of incorrect handling, the brake fluid can cause
serious injury and damage. Follow the manufacturer's
instructions for brake fluid.
To prevent dust from entering the master cylinder res-
ervoir and the brake circuit, the plug must be removed
just before filling and closed immediately afterwards,
2 - Instructions to be followed during the operation
Do not press on the brake pedal during work on the
brake system.
If, during work on the brake system, any damage on
any part is observed, it must be repaired before driving
the vehicle again.
Brake fluid is highly corrosive. Ensure any brake fluid
spilt on parts of the vehicle is cleaned off.
Use brake fluids that comply with the Renault standard
(see Vehicle: Parts and consumables for the repair)
.
Check the brake fluid levels in the braking circuit and
the bleeding device.
Check that the pressure of the bleeding device is be-
tween 1.5 bar and 2 bar.
II - CLEANLINESS
1 - Advice to be followed before any operation
Protect any bodywork components that risk being dam-
aged by brake fluid with a cover.
2 - Instructions to be followed during the operation
Fit blanking plugs recommended for the Siemens K9K
injection system at the end of each pipe and in all the
openings of the disconnected components of the brake
circuit.
Clean around the braking system with BRAKE
CLEANER (see Vehicle: Parts and consumables
for the repair) (04B, Consumables - Products).Do not allow friction materials to come into contact with
grease, oil or other lubricants and cleaning products
which are mineral oil based.
III - GENERAL RECOMMENDATIONS
When replacing brake pads, always replace the pads
on the other side as well.
When replacing a disc, always replace the disc on the
opposite side.
When replacing brake discs, you must replace the
brake pads.
Always replace the rigid brake pipe clips.
Reminder:
-The pipes between the master cylinder, callipers and
the hydraulic assembly are connected using threaded
unions with a metric thread.
-Therefore, only parts specified in the Parts Catalogue
for this vehicle should be used. WARNING
Prepare for the flow of fluid, and protect the sur-
rounding components.
WARNING
In order not to damage the brake hose:
-do not tension the hose,
-do not twist the hose,
-check that there is no contact with the surrounding
components, regardless of the position of the
wheels.
IMPORTANT
To avoid any accident, br ing the pistons, brake pads
and brake discs into contact by depressing the
brake pad several times.

GENERAL INFORMATION
Braking circuit: Bleed
30A
aConnect the brake circuit bleeding device (after
having received Renault approval) to the master cyl-
inder reservoir (see the instructions for the equip-
ment).
aPressurise the brake circuit.
aAdjust the pressure to between 1.5 bar < P < 2 bar
for 3 minutes to stabilise it in the braking circuit.
aClose the circuit between the bleed screw and brake
fluid reservoir without dumping the pressure.
aFit the bleed containers to the four bleed screws of
the callipers.
aUndo the calliper bleed screws:
-front left-hand,
-front right-hand,
-rear left-hand,
-rear right-hand.
aOpen the circuit between the bleed screw and brake
fluid reservoir and allow the liquid to run until all the
air bubbles have been released.
aTighten the bleed screws in the following order:
-front left-hand,
-front right-hand,
-rear left-hand,
-rear right-hand.
aUndo 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.
aCarry out the previous operation on the callipers:
-front right-hand,
-rear left-hand,
-rear right-hand.
aClose the bleed screw to dump the pressure in the
brake circuit.aRemove the brake circuit bleeding device from
the master cylinder reservoir.
aCheck 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.
aTop 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) .
aDuring a road test, trigger braking regulation to con-
firm that the brake pedal travel is correct.
aClean 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.
