Hydraulic System Bleeding

Print

See Figure 1

This procedure may be utilized when either the clutch master or release cylinder has been removed or if any of the hydraulic lines have been disturbed.


CAUTION
Do not spill brake fluid on the body of the vehicle as it will destroy the paint.

  1. Fill the master cylinder reservoir with brake fluid.
  2.  
  3. Remove the cap and loosen the bleeder screw on the clutch release cylinder. Cover the hole with your finger.
  4.  
  5. Have an assistant pump the clutch pedal several times. Take your finger off the hole while the pedal is being depressed so that the air in the system can be released. Put your finger back on the hole and release the pedal.
  6.  
  7. After fluid pressure can be felt (with your finger) tighten the bleeder screw.
  8.  
  9. Put a short length of hose over the bleeder screw and place the other end into a jar half full of clean brake fluid.
  10.  
  11. Depress the clutch pedal and loosen the bleeder screw. Allow the fluid to flow into the jar.
  12.  
  13. Tighten the plug and then release the clutch pedal.
  14.  
  15. Repeat Steps 6-7 until no air bubbles are visible in the bleeder tube.

  17. When there are no more air bubbles in the system, tighten the plug fully with the pedal depressed. Replace the plastic cap.
  18.  
  19. Fill the master cylinder to the correct level with brake fluid.
