What Is Clutch Slip & Drag?
Clutch slipping and clutch drag are two problems that can occur as clutches wear out. They are opposite problems that can occur with any clutch on any type of vehicle and require some type of repair to remedy the problem lest the clutch system become damaged.
When the clutch pedal is pushed, the clutch responds by slipping to prevent jolts to the vehicle or damage to the transmission; however, once the pedal is released, the clutch should not slip. Slip occurs when the drive disk rotates at a different speed than the driven ditch.
Signs of clutch slip include poor gas mileage, the need to downshift more frequently when going down a hill and the sound of a revving engine when starting from a dead stop. Additionally, the clutch pedal may feel stiff.
In addition to general wear and tear, clutch slip can be caused by excess oil on the clutch or problems with the master cylinder, release system or cable adjuster.
Clutch drag occurs when the disc attached to the clutch pedal continues to spin even after the clutch has been released.
Clutch drag is usually recognised by difficulty shifting gears. This may or may not be associated with a grinding sound.
Causes of clutch drag vary depending on clutch type. Generally, some common causes are problems with binding cables, pedal brackets and the master or slave cylinders.
