Maintenance operations
Tighten the bleed valve (5) to a torque of 4 Nm
Repeat the operation described above until the old liquid flows completely.
Then, with the bleed valve definitely closed to the specified torque actuate repeatedly the lever until a pressure is
detected in the brake system.
Warning
After eliminating the old fluid from the tank, during the refilling operation always keep the oil level above the MIN mark to
prevent the formation of air bubbles inside the circuit.
Changing the rear brake circuit fluid
Unscrew the cap (6) of the rear brake fluid reservoir (7).
Attach a length of transparent plastic tubing to the bleed valve (8) and insert the other end of the tubing in a container
placed on the floor.
Siphon off the fluid from the reservoir (6).
Fill the reservoir (7) with new brake fluid up to the MAX mark.
Warning
While filling the system, always keep the fluid level above the MIN mark to prevent the formation of air bubbles in the
circuit.
Allow the fluid to flow from the bleed valve (8) until it changes colour.
Operate the brake pedal two or three times to pressurise the circuit.
Hold the pedal pressed down.
