Why does the clutch shake when pressed?
2 Answers
The reasons for clutch shaking when pressed are: 1. Uneven pressure distribution in the car's clutch; 2. Excessive elasticity of the clutch pressure spring; 3. Insufficient lubrication causing stiffness in components like the release sleeve and release fork shaft; 4. Oil contamination or breakage of the driven disk lining; 5. Bending of the main or driven disk, or inconsistent height of the release levers. Solutions for clutch shaking: 1. Readjust the pressure distribution of the car's clutch; 2. Replace the clutch pressure spring with one of suitable size; 3. Add lubricant between components like the release sleeve and release fork shaft; 4. Replace the damaged driven disk lining.
I've been driving for over 20 years, and clutch pedal shudder is quite common, especially in older vehicles. My car used to start shuddering at around 50,000 kilometers – turns out it was caused by uneven wear on the clutch disc or pressure plate deformation. When the friction material wears thin, engagement becomes unstable, and you can feel the vibration through the pedal. It might also relate to flywheel surface irregularities that require professional resurfacing equipment. Driving habits matter tremendously: minimize riding the clutch, avoid prolonged pedal depression, and shift to neutral in city traffic jams to prevent clutch overheating. Additionally, damaged engine mounts or worn motor mounts can transmit vibrations, making the entire car shake. Low hydraulic fluid levels or leaks in the clutch system also cause shuddering, so regular fluid checks are essential. Prolonged shuddering without repair significantly increases clutch slippage and stall risks, particularly dangerous on highways. I recommend having technicians measure clutch free play during every maintenance service and replacing components promptly when needed. Safety comes first – never cut corners with DIY fixes to save money.
