Why is there a knocking sound when releasing the clutch pedal quickly?
1 Answers
A knocking sound at the moment of clutch engagement is caused by transmission linkage jamming, which makes the pressure plate suddenly press against the driven plate resulting in jerking, or by a deformed driven plate or oil-contaminated friction lining, leading to abrupt clutch engagement and impact. It is recommended to have it checked at a 4S shop. Below is relevant information: Automobile Clutch: The automobile clutch is the control device of the manual transmission clutch assembly. Its correct operation directly affects the vehicle's starting, gear shifting, and reversing. Automobile Clutch Operation Method: The clutch pedal release follows the principle of "two fast, two slow, and one pause." Poor coordination between the clutch and throttle during vehicle starting can cause the engine to stall or the car to shake when starting.
