Yes, PPs do "go bad". The springs get weak, which reduces the clamping force, the surface wears (just like brake rotors), and the release fingers wear at the contact points with the throw-out bearing. Throw-out bearings have similar wear issues, and like any bearing they do go bad.
Subsequently, one may also ask, how do I know if my clutch pressure plate is bad?
Symptoms of a damaged clutch pressure plate:
- Lack of vehicle power.
- Higher RPM.
- Difficulty in engaging or shifting gears.
- Reduced clutch pedal resistance.
- Burning smell from the clutch.
- Inability to tow a trailer or difficulty driving up hills.
Keeping this in consideration, do clutch pressure plates wear out?
This part is often replaced when replacing a worn clutch disc. 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.

- Hard to Shift.
- Pedal Stuck to the Floor.
