What are the symptoms of a bad clutch disc?

[HannahRose]

Here are the manifestations of a bad clutch disc: 1. The clutch engagement point becomes higher. When starting the vehicle, you need to depress the clutch pedal. Originally, releasing it by 1 cm would make the car move, but now you have to release it to 2 cm. This is caused by the thinning of the clutch disc; 2. The car's power feels reduced. When there's no abnormality in the engine, whether starting or climbing a slope, the car feels weak. Even with high engine RPM, there's insufficient power, indicating clutch slippage; 3. When depressing or releasing the clutch pedal, you hear a metal friction sound, which is the result of severe wear on the clutch disc; 4. When starting and releasing the clutch, you feel unevenness, with the car jerking forward and backward. There's a rough sensation when engaging or disengaging the clutch, indicating the need for clutch disc replacement. The car clutch disc is the medium that transmits engine power to the transmission. Similar to brake pads, the friction material of clutch discs is mainly asbestos-based, offering certain high-temperature resistance.
