Checks and inspections

WARNING
Always change the gaskets when re-assembling.

CHECKS AND INSPECTIONS

• Check the piston and the cylinder inner surface for scores or traces of rust and change the cylinder assembly if necessary.
• Check that the spring is intact.
• Check that the air relief hole is not clogged.

BLEEDING AIR FROM THE HYDRAULIC SYSTEM

WARNING:
Never re-use the hydraulic fluid resulting from the bleeding operation.

1. Remove the cap on the clutch and brake fluid reservoir and if necessary top up the level with the specified fluid.
2. Remove the protective cap from the relief screw on the cylinder and push a hose onto the screw with the other end in a transparent container full of the same hydraulic fluid as the circuit.
3. Slacken the relief screw while pressing the clutch pedal allowing it to return slowly; repeat this operation until all the air trapped in the circuit has been eliminated.

• Then with the clutch pedal completely depressed, tighten the relief screw, remove the hose and refit the protective cap.

During the bleeding operation, the level of the fluid in the reservoir must never fall below the "MIN" mark.

• Top up the level of the fluid in the reservoir and refit the cap.

Brake/clutch fluid can damage the paintwork, therefore proceed with care.

• After bleeding, check that the clutch and gears disengage and engage properly.

1. Also check that the disengagement stroke of the clutch control cylinder is within the specified limits.

This stroke is not adjustable and depends on the volume of the fluid displaced by the clutch pump piston.

MINIMUM BRAKE - CLUTCH FLUID LEVEL SENSOR

REMOVAL/REFITTING

• Disconnect the battery (-) terminal.

1. Disconnect the electrical connection from the minimum brake-clutch fluid level sensor.
2. Slacken the cap with the built-in minimum brake-clutch fluid level sensor and remove it.
