Bleeding The Hydraulic System



Bleeding air from the hydraulic clutch system is necessary whenever any part of the system has been disconnected or the fluid level (in the reservoir) has been allowed to fall so low, that air has been drawn into the master cylinder.

  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Fill master cylinder reservoir with new brake fluid conforming to DOT 3 specifications.
    CAUTION
    Always use new fluid from a sealed container. Never, under any circumstances, use fluid that has been bled from a system to fill the reservoir as it may be aerated, have too much moisture content and possibly be contaminated.

  4.  
  5. Pump the clutch pedal up and down at least 15 times.
  6.  
  7. Have an assistant fully depress and hold the clutch pedal, then open the bleeder screw.
  8.  
  9. Close the bleeder screw and have your assistant release the clutch pedal.
  10.  
  11. Repeat the procedure until all of the air is evacuated from the system. Check and refill master cylinder reservoir as required to prevent air from being drawn through the master cylinder.
    NOTE
    Never release a depressed clutch pedal with the bleeder screw open or air will be drawn into the system.

  12.  
  13. Test the clutch for proper operation.

Master Cylinder
Bench Bleeding Procedure

CAUTION
DO NOT use fluid which has been bled from a hydraulic clutch system, in order to fill the clutch master cylinder reservoir, due to the possibility that the fluid may be aerated, have too much moisture content, or be contaminated and may cause system or vehicle damage.

  1. Ensure the reservoir is filled to the fill line with new hydraulic fluid. Add fluid if required from a clean sealed container.
  2.  
  3. Pump the clutch pedal from the up stop to the down stop position at least 15 times.
  4.  
  5. With the pedal in the down stop position. Open the bleeder valve (1) to release the trapped air.
  6.  
  7. Close the bleeder valve (1) and slowly return the clutch pedal to the up stop position.
  8.  
  9. Open the bleeder valve (1) and slowly depress the clutch pedal from the up stop to the down stop position until fluid escapes through the bleeder.
  10.  
  11. Close the bleeder valve.
  12.  
  13. Return the clutch pedal to the up stop position.
  14.  
  15. Depress the clutch pedal from the up stop to the down stop position.
  16.  
  17. Open the bleeder valve (1) and allow fluid with air bubbles to escape through the bleeder valve.
  18.  
  19. Close the bleeder valve.
    NOTE
    Always make sure that the clutch fluid reservoir remains filled with new clean hydraulic fluid.

  20.  
  21. Repeat steps 7-10 until fluid without air bubbles escapes through the bleeder valve.
  22.
