BRAKESBLEEDING AND FILLING THE BRAKING SYSTEM
Bleeding the braking circuit without the bleed apparatus.
NOTE:Two operators are necessary.
For each brake circuit:
- Apply the brake pedal to place the circuit under pressure.
- Couple a transparent tube on the bleed screw.
- Submerge the other end of the tube in a clean container.
- Open the bleed screw.
- Wait until the fluid flows out without air bubbles.
- Close the bleed screw.
NOTE:Recommence the process a second timeif that is necessary.
Check the level of the brake fluid
(between the «DANGER»level and
the «MAXI»level).
Fill if necessary with the the approved and recommended synthetic
brake fluid.Bleeding the secondary braking circuit.
WARNING: During the bleed operations: take care to maintain the
level of the brake fluid in the reservoir, keep it topped up.
