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.

BRAKES
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.

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.
