BRAKE FLUID CHECKS
IMPERATIVE: Respect the safety and cleanliness requirements.
WARNING: Brake fluid is toxic to health. Avoid any contact with your skin or with your eyes. If there is contact with your eyes, rinse immedia-
tely with copious amounts of water for several minutes.
WARNING: Brake fluid is highly corrosive to paintwork. If there is spillage onto the bodywork, clean the surface immediately.
Tools: Brake fluid tester (*):
Supplier Reference Type
SURETEST TLF
DOW AUTOMOTIVE BETATEST Measures the boiling point of brake fluid
FACOM OUTILLAGE DF.16
EBT 06.1 Measures the rate of hydrometry of brake fluid
(*) The list not exhaustive, refer to the catalogue "Tools and Equipment".
Checks.
Remove the filter of the brake fluid reservoir.
IMPERATIVE: Any pollution of the brake fluid is forbidden. The brake fluid should be limpid and free of suspended matter or sediments.
Check the brake fluid, following the method recommended by the supplier of the testing equipment.
Test values:
Brake fluid Minimum boiling point «Humid»
DOT 3 140°C
DOT 4 155°C
SUPER DOT 4
180°C
DOT 5
NOTE:If the tested value is lower than the minimum "humid"boiling point or within a tolerance of +10 %of this value, replace the brake fluid
(see corresponding operation).
IMPERATIVE: Use exclusively the hydraulic fluids that are approved and recommended.

BRAKES
DRAINING, FILLING AND BLEEDING THE BRAKING SYSTEM
Filling the braking circuit.
WARNING: Use only the approved and recommended hydraulic fluids.
IMPERATIVE: Only use new brake fluid that has not emulsified; avoid any introduction of
impurities into the hydraulic circuit.
Fill the brake fluid reservoir (4).
Bleeding the primary braking circuit.
WARNING: During the bleed operations: take care to maintain the level of the brake fluid in
the reservoir, keep it topped up.
WARNING: The ABS system must not be in action during the bleed operation.
WARNING: Respect the sequence for the opening of the bleed screws.
Frontbrake caliper : Bleed screw (5).
Rearbrake caliper : Bleed screw (6).
Bleed each brake caliper, proceeding in the following sequence:
- Front LH wheel.
- Front RH wheel.
- Rear LH wheel.
- Rear RH wheel.

DRAINING, FILLING AND BLEEDING THE BRAKING SYSTEM
Bleeding the secondary braking system.
WARNING: During the bleeding operation, take care to maintain the level of brake fluid in
the reservoir and to top it up.
NOTE:Connect the bleeding apparatus [1]on the brake fluid reservoir (4).
Use the diagnostic tools [2] or [3].
Select the menu ESP VSC 440.
Bleed sequence: Menu ESP.
- Front LH wheel.
- Front RH wheel.
- Rear LH wheel.
- Rear RH wheel.
Follow the instructions given by the diagnostic tool.
At the end of the bleeding programme, check the brake fluid level and top up, if necessary.
Check the brake pedal travel (no lengthening), if not satisfactory repeat the bleeding procedure.

HYDRAULICS
SAFETY REQUIREMENTS: ACTIVE SUSPENSION WITH VARIABLE DAMPING
During the operation.
Wait for the pressure in the hydraulic circuit to fall fully before disconnecting the unions on the following components (risk of sudden sinking of the
vehicle):
- Built-in Hydro-electronic Interface (BHI).
- Front suspension cylinder.
- Rear suspension cylinder.
- Front stiffness regulator.
- Rear stiffness regulator.
- Suspension pressure sensors.
IMPERATIVE: Do not operate on the hydraulic circuit without making the pressure drop (see corresponding operation).
Engine running.
Do not operate on the hydraulic suspension circuit.
Always remain out of range of any possible projections of fluid, as these could cause serious injuries.
NOTE:In the event of contact of LDSfluid with the eyes, rinse them with copious amounts of water and seek specialist advice.
NOTE:In the event of lengthy contact of LDSfluid with the skin, wash it with soap and water.
WARNING: After the engine has stopped, wait 30 seconds before commencing any operation.

SAFETY REQUIREMENTS: ACTIVE SUSPENSION WITH VARIABLE DAMPING
IMPERATIVE: Do not remain underneath the vehicle during an operation to adjust vehicle heights or during actuator (electrovalve) tests.
IMPERATIVE: Any deforming of the wheel travel sensor supports is forbidden. If there is any deformation found, replace the component.
Cleanliness requirements.
WARNING: Non-respect of the cleanliness requirements may cause a contamination of the circuit and a malfunctioning of the suspension.
Preliminary operations.
The work area must be kept clean and uncluttered.
The technician must wear clean overalls.
