Why does the foot shake when stepping on the clutch while driving?
2 Answers
The main reason for clutch shaking while driving is the uneven pressure distribution of the car's clutch, which leads to loose or broken springs and incorrect pressure positions, resulting in clutch instability. Below are the specific reasons for clutch shaking while driving: Excessive tension of the clutch pressure spring: Readjust the pressure distribution of the car's clutch. Excessive tension of the clutch pressure spring causes the clutch to shake. Replace the clutch pressure spring with one of the appropriate size. Insufficient lubrication of components such as the release sleeve and release fork shaft leads to clutch shaking. Oil contamination on the driven plate lining: Add lubricant between components such as the release sleeve and release fork shaft. Oil contamination or cracks on the driven plate lining, or uneven thickness of the driven plate can cause shaking. Replace the damaged driven plate lining. Bent main or driven plate: Clutch shaking caused by inconsistent heights of the release levers. Identify the fault and complete the repair.
When I first started learning to drive, my leg would always shake when pressing the clutch, mainly due to nervousness and uncoordinated movements. Beginners are unfamiliar with the clutch engagement point and fear stalling, so they end up keeping their foot too tense. Additionally, if the seat is adjusted too far forward, the ankle has no support, causing the calf to ache and tremble after just half an hour of driving. My suggestion is to first adjust the seat so that your knees are slightly bent when fully depressing the clutch, and keep your heel grounded instead of hovering. Practice the half-clutch technique on flat ground to familiarize yourself with the engagement point—once you know it, you'll feel more confident and less nervous. Also, wearing soft-soled shoes makes it easier to control the pressure compared to hard-soled boots. If you're driving long distances, remember to take a 10-minute break every two hours to stretch and massage your legs.
