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. Fill master cylinder reservoir with new brake fluid conforming to DOT 3 specifications. Check manufactures recommendations for each vehicle.




  1. Raise and safely support the vehicle high enough to work comfortable under it.



  2. Have an assistant fully depress and hold the clutch pedal, then open the bleeder screw of the slave cylinder or concentric cylinder.



  3. Close the bleeder screw and have your assistant release the clutch pedal.



  4. 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.


Never release a depressed clutch pedal with the bleeder screw open or air will be drawn into the system.




  1. Lower the vehicle and test clutch operation.



  2. If the previous steps do not result in satisfactory pedal feel, remove the reservoir cap and pump the clutch pedal very fast for 30 seconds. Stop to let the air escape, then repeat the procedure as necessary to purge all remaining air.



  3. Check the master cylinder fluid level and replenish as necessary.
