  1. Remove the slave cylinder from the vehicle.
  2.  
  3. Remove the pushrod and boot.
  4.  
  5. Force out the piston by blowing compressed air into the slave cylinder at the hose connection.
  6.  


CAUTION
Be careful not to apply excess air pressure to avoid possible injury.

  1. Clean all of the parts in clean brake fluid.
  2.  
  3. Check and replace the slave cylinder bore and piston if wear or severe scoring exists. Light scoring and glaze can be removed with crocus cloth soaked in brake fluid.
  4.  
  5. Normally the piston cup should be replaced when the slave cylinder is disassembled. Check the piston cup and replace it if it is found to be worn, fatigued or scored.
  6.  
  7. Replace the rubber boot if it is cracked or broken.

Fig. Fig. 3 Pump the clutch pedal several times, release the clutch pedal, then open the bleeder screw-repeat as necessary

  1. Check and fill the clutch fluid reservoir to the specified level as necessary. During the bleeding process, continue to check and replenish the reservoir to prevent the fluid level from getting lower than 1 / 2 the specified level.
  2.  
  3. Remove the dust cap from the bleeder screw on the clutch slave cylinder and connect a tube to the bleeder screw and insert the other end of the tube into a clean glass or metal container.
  4.  

Take precautionary measures to prevent the brake fluid from getting on any painted surfaces.

  1. Pump the clutch pedal SLOWLY several times, hold it down and loosen the bleeder screw.
  2.  
  3. Tighten the bleeder screw and release the clutch pedal gradually. Repeat this operation until air bubbles disappear from the brake fluid being expelled out through the bleeder screw.
  4.  
  5. Repeat until all evidence of air bubbles completely disappears from the brake fluid being pumped out through the tube.
  6.  
  7. When the air is completely removed, securely tighten the bleeder screw and replace the dust cap.
  8.  
  9. Check and refill the master cylinder reservoir as necessary.
  10.  
  11. Depress the clutch pedal several times to check the operation of the clutch and check for leaks.
