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.

BRAKE FLUID REPLACEMENT INTERVAL
Our braking technology, and in particular the disc
brakes (hollow pistons which conduct little heat, have a
low volume of fluid in the cylinder, sliding callipers
avoiding the need for a fluid reserve in the least cooled
area of the wheel), has allowed us to prevent the risk of
« vapour lock » as far as possible, even with heavy
braking (mountainous area). However, current brake
fluids are subject to minor deterioration during the first
months of use due to slight humidity intake. This is why
it is recommended that you change the brake fluid: see
maintenance booklet for the vehicle.
1 - Topping up the level
Wear of the brake pads will result in a gradual drop in
the fluid level in the reservoir.
Do not top up the fluid, as the level will rise again when
the pads are next changed. The brake fluid level must
not fall below the minimum mark.
2 - Approved brake fluid
Mixing two incompatible brake fluids in the brake circuit
may lead to:
-serious risk of leakage due mainly to deterioration of
the cups,
-deterioration in the operation of the ESP system.
To prevent such risks, it is essential to use only brake
fluids that comply with the RENAULT standard (see
Vehicle: Parts and consumables for the repair) .
