Pressure Plate
What Is It?
A diaphragm spring arranged around a thick central steel alloy plate.
What Is It’s Job?
When pressure is applied to the diaphragm spring the pressure plate moves back slightly which breaks drive transmission to the pressure plate.
Typical Issues
- Slipping
- Excessive Noise
- Engine Revving Higher Than Usual
- Gears Difficult To Select
How To Fix
Pressure plate replacement.
Friction Plate
What Is It?
A relatively thin circular outer metal alloy chassis attached to a metal splined center plate with a bonded heavy duty lined surface.
What Is It’s Job?
Clutch Pedal Up
Pedal up your friction plate is sandwiched between the pressure plate and the engines flywheel allowing straight through one to one drive.
Clutch Pedal Down
When your clutch pedal is fully pressed the clutch pressure plate is forced away from the friction plate allowing the clutch friction plate to spin freely from drive.
Clutch Pedal Midway
When you partially press your clutch pedal drive transfers at less than one to one. This is what you will recognise as clutch control.
Typical Issues
- Slipping
- Excessive Noise
- Engine Revving Higher Than Usual
- Difficulty Selecting Gears
How To Fix
Replace your friction plate.
Thrust Bearing
What Is It?
A circular metal alloy body containing bearings which allow the bearing face to spin freely.

Look for fluid leaking around your clutch master and slave cylinders as well as any associated pipes and connections and replace accordingly. Check for worn cylinder seals at the pedal end.
