Slipping occurs when the disc fails to rotate at the same speed as the clamping components when the clutch is engaged. Essentially it is when the pressure plate fails to hold the disc tight against the face of the flywheel. 

Potential causes of slip: 

  1. Improper break-in procedure  
  2. The vehicle is overpowering the clutch  
  3. Driver resting a foot on the clutch pedal causing the bearing to ride on the pressure plate and keeping the plate in slightly release position. 
  4. Faulty hydraulic hindering the pressure plate from fully releasing.  

Slipping related to clutch adjustment: 

  1. An improper clutch adjustment can cause slippage by holding the release bearing in contact with the pressure plate which can cause the pressure plate to stay in a slightly released position. 
  2. A binding linkage that would prevent the pressure plate from exerting full pressure against disc 

Other potential causes of slip: 

  1. A seized hydraulic system  
    • This can be caused by broken motor mounts producing excessive engine movement 
  2. A leaking master/slave cylinder 
  3. Grease and/or oil on the disc  
  4. Damaged or bent clutch disc 
  5. Clutch disc has broken or missing friction material 
  6. The friction material of the clutch disc is glazed from overheating 
  7. Flywheel improperly resurfaced or incorrect step  
  8. Improper or damaged release bearing
