How often do you press the clutch pedal?
There are two basic ways a clutch fails – it either fails to disengage, or fails to engage fully. In normal, modern stop-and-go driving, you probably press the clutch pedal in every few seconds. And on that one time when you press it and the car still creeps forward, you know you have a problem.
What causes a clutch to not engage fully?
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.
What causes a clutch master cylinder to leak?
When the clutch pedal is pressed, the clutch master cylinder pushes fluid through the system down to the clutch slave cylinder so that it may disengage the clutch. As they are hydraulic in nature, clutch master cylinders are often prone to issues with leaks that will interfere with its ability to displace fluid.
What are the symptoms of a bad clutch cylinder?
1. Low or dirty clutch fluid One of the first symptoms commonly associated with a potential problem with the clutch master cylinder is low or dirty fluid in the reservoir. Dirty fluid can be caused by the seals inside the master cylinder breaking down due to wear and old age and contaminating the fluid.
Why does my clutch pedal not depress at all?
IIRC, a worn out master cylinder will make the pedal dead through much of the area… and if you just hold pressure on the clutch pedal, w/out pushing it to the floor, it’ll eventually get to the floor anyway b/c the fluid is leaking out/around the MC and the clutch will eventually engage whether you want it to or not.

What causes free play on a clutch clutch?
Free play is the distance between the release bearing and the pressure plate fingers. Anytime the clutch slips, it’s creating heat and damaging the pressure plates surface. Excessive wear on the diaphragm’s fingers can be caused by a defective or worn release bearing.
Why does clutch chatter go away after applying the clutch?
Clutch chatter occurs when the clutch is first applied and goes away after the clutch has fully engaged. Clutch slippage is the continued spinning of the clutch disk without its full engagement. Faulty dual mass flywheels and worn or over machined flywheels result in clutch slippage.
