What are the symptoms of a burnt clutch plate?
2 Answers
The symptoms of a burnt clutch plate include: 1. The clutch pedal engagement point becomes higher. When starting the vehicle, you may need to lift the pedal to 2 cm instead of the usual 1 cm before the car moves, which is likely caused by the thinning of the clutch plate; 2. Even when the engine is running normally, the car feels underpowered during starting or climbing hills, with the engine revving high; 3. A metallic grinding noise can be heard when pressing or releasing the clutch pedal; 4. Uneven or rough sensation when operating the clutch pedal. The clutch plate is the medium that transmits engine power to the transmission. Similar to brake pads, clutch plates mainly use asbestos-based friction materials that have certain high-temperature resistance capabilities.
A burnt clutch disc feels quite noticeable. I drive a manual transmission, and the last time I encountered this issue, the engine revs surged when accelerating, but the car didn't gain speed—it felt like it was spinning freely. There was a strong burnt smell inside the car, sharp and lingering, not dissipating even with the windows down. When starting or climbing hills, the car shook violently, as if the entire chassis was vibrating. The clutch pedal became heavier to press, and gear shifts felt rough or difficult, sometimes accompanied by clicking or grinding noises. Increased noise was another clear sign, making driving uncomfortable. The cause might be prolonged driving in a semi-engaged clutch state, like constantly depressing the clutch in traffic, leading to overheating and burning. Ignoring these symptoms can result in complete clutch failure or even damage to the transmission. That repair cost me a lot—lesson learned: avoid aggressive throttle use and gear dragging, and regularly check clutch fluid levels and condition.
