5. If the clutch pedal free play and the distance

between the clutch pedal and the clutch pedal
stopper or dash pad when the clutch is
disengaged do not agree with the standard
values, it is probably the result of either air in the
hydraulic system or a faulty master cylinder,
release cylinder or clutch. Bleed the air, or
disassemble and inspect the master cylinder,
release cylinder or clutch.

CLUTCH BLEEDING

M1211001400216

CAUTION

Use the specified brake fluid. Do not mix brake
fluids.

Specified fluid: Brake fluid DOT 3 or DOT 4

AC211514 AB

1. Connect a hose with a bottle to the bleeder screw.
2. Open the bleed nipple.

CAUTION

For bleeding, never "pump" the clutch pedal.
This may cause an oil leak at the clutch cylinder.
3. Depress the clutch pedal slowly. Open the bleeder

screw to let air and brake fluid out. Close the
bleeder screw. Release the clutch pedal. Repeat
until only brake fluid and no air comes out.

4. Check that the brake fluid reservoir level stays

between "MAX" and "MIN" marks throughout the
clutch bleeding process.

CLUTCH SWITCH CHECK AND
ADJUSTMENT
