What causes a clutch to fail suddenly?
Sudden clutch failure can also be caused by problems with the pressure plates that squash the friction plate onto the flywheel. If the springs behind these plates fail, you might feel the clutch pedal go very heavy and then you’ll lose drive. Is it the clutch or gearbox?
How do I know if my clutches are bad?
Clutch issues can also lead to DMF damage. For example, if the clutch’s friction lining wears out completely through excessive clutch slip, the plate’s metal backing will grind into the DMF’s surface. This can be identified through a visual inspection; damage will show a discoloured friction surface on the secondary flywheel.

Can you replace a clutch and DMF?
It’s clear that replacing a vehicle’s clutch and DMF during the same repair operation is extremely practical for both the workshop and the customer. However, when comparing price and availability of parts for the job, the workshop may end up buying a clutch from one brand and a DMF from another brand, with both parts possibly purchased from different motor factors. In addition to being a time consuming way of sourcing components, any brand mismatch introduces the potential for incompatibility in the clutch and DMF system.
What does it mean when a clutch doesn't engage?
A clutch that doesn't engage fully, or slips under heavy load, is the normal failure mode of a worn out friction disc of pressure plate that has lost its tension. When you press the clutch, your foot counters the diaphragm spring which presses the friction disc to the flywheel.
Why is my clutch pedal not engaging?
Beside not engaging, or not disengaging, there can be other issues as well, such as noisy operation, or chattering on engagement. On older mechanical linkages, lack of periodic lubrication can lead to high effort or binding in pivots or cables, or a pedal that does not return smoothly. A bad throwout bearing can be a major headache in stop and go traffic, making horrible noises every time the clutch pedal is depressed. These are often annoyances more than anything else, especially since fixing them often involves removing the transmission/transaxle to get to the parts.

Why does my clutch slip?
If the spring pressure is not great enough , or the clearance between all the parts is too great, there won't be enough friction to transmit the power from the motor to the transmission.
