BLEEDING AND FILLING 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.
Front brake caliper : Bleed screw (8).
Rear brake caliper : Bleed screw (9).
Bleed each brake caliper, proceeding in the following sequence:
- Front LH wheel.
- Front RH wheel.
- Rear LH wheel.
- Rear RH wheel.
