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.

DRAINING, FILLING AND BLEEDING THE BRAKING SYSTEM
Using the bleeding apparatus.
Connect the bleeding apparatus [1]on the brake fluid reservoir (4).
Adjust the apparatus pressure to 2 bars.
For each brake circuit:
- Connect a transparent tube onto the bleed screw.
- Submerge the other end of the tube in a clean container.
- Open the bleed screw.
- Wait until the fluid is flowing out without air bubbles.
- Close the bleed screw.
- Remove the bleeding apparatus.
- Check the brake fluid level (should be between «DANGER»level and «MAXI»level).
- Fill if necessary with the approved and recommended synthetic brake fluid.
Without bleeding apparatus.
NOTE:Two operators are necessary.
For each brake circuit:
- Apply the brake pedal to place the circuit under pressure.
- Connect a transparent tube onto the bleed screw.
- Submerge the other end of the tube in a clean container.
- Open the bleed screw.
- Wait until the fluid is flowing out without air bubbles.
- Close the bleed screw.
NOTE:Recommence the process a second timeif that is necessary.
- Check the brake fluid level (should be between «DANGER»level and «MAXI»level).
- Fill if necessary with the approved and recommended synthetic brake fluid.

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.
