Clutch: Service and Repair

Air Bleeding of Clutch System

CAUTION: Brake fluid is extremely damaging to paint. If fluid should accidentally touch painted surface, immediately wipe fluid from paint and clean painted surface.

Bleeding operation is necessary to remove air whenever it entered hydraulic clutch system.

1. Fill master cylinder reservoir with brake fluid and keep at least one-half full of fluid during bleeding operation.





2. Remove bleeder plug cap. Attach a vinyl tube (1) to bleeder plug, and insert the other end into container (2).





3. Depress clutch pedal several times, and then while holding it depressed, loosen bleeder plug about one-third to one-half turn.
4. When fluid pressure in cylinder is almost depleted, retighten bleeder plug.
5. Repeat this operation until there are no more air bubbles in hydraulic line.
6. When bubbles stop, depress and hold clutch pedal, and tighten bleeder plug.
Tightening torque
Clutch bleeder plug: 5 Nm (0.5 kgf-m, 4.0 ft. lbs.)
7. Then attach bleeder plug cap.
8. After completing bleeding operation, apply fluid pressure to pipe line and check for leakage.
9. Replenish fluid into reservoir up to specified level.





10. Check clutch pedal for sponginess. If found spongy, repeat entire procedure of bleeding.
