What are the causes of clutch pedal vibration?
When stepped on, the clutch pedal that vibrates indicates that your car clutch has a problem and requires corrective action to prevent severe damage from breaking down on the road. Also, the vibration that occurs in the clutch pedal when stepped on will impact driving discomfort. The vibrating clutch pedal can cause your feet to become sore faster, which affects your concentration while driving.
Therefore, when the clutch pedal vibrates has appeared and felt in your car, it is better to fix it immediately because it requires a longer repair time. So, what are the causes of clutch pedal vibration? The following article provides information about the clutch pedal vibration cause, mostly when we stepped on that pedal.
1. The flywheel surface is wavy.
The first cause of the clutch pedal to vibrate when stepped on is the wavy flywheel surface. This uneven flywheel surface will be affecting the rotation of the clutch disc when connected and makes vibrations that will spread up to the clutch pedal.
Many things can cause the flywheel's wavy surface which is in contact with the clutch disc, such as improper use of the clutch, clutch slip, run-out clutch disc, etc.
Therefore, when replacing the clutch assy, checking the flatness of the flywheel surface is also necessary. The solution to this problem is to lathe the flywheel surface or replace it with a new flywheel.
2. The clutch cover spring is weak
The next cause for the clutch pedal vibrating problem is that the clutch cover spring is weak, so the force is uneven. This uneven clutch cover spring will create irregular contact between the spring and the clutch release bearing. As a result, there is a vibration in the release bearing spread up to the clutch pedal.
This weak clutch cover spring is typically due to its running out of life, and the solution to this problem is to replace it with a new clutch cover.
3. Worn-out clutch release bearing
Worn-out clutch release bearing can also be the cause of the clutch pedal to vibrate when stepped on. Inside the clutch release bearing, a bearing continues to rotate when you step on the clutch pedal.
When the bearings inside the clutch release bearing are worn-out, the clutch release bearing rotation is no longer balanced and shakes. As a result, it will cause vibrations that spread up to the clutch pedal.

Apart from damage to the clutch components, the clutch bolts' uneven tightening can also cause the clutch pedal to vibrate when stepped on. The clutch plate installation has rules that cannot ignore.
One of them is during the process of tightening the bolts on the clutch cover. It is mandatory to use a torque wrench and the same torque size to tighten the clutch cover bolt. The clutch cover bolts can affect the flatness and height of the clutch cover spring surface.
When the tightening of the bolts is uneven, the clutch cover spring's surface will also become uneven. The result can cause vibrations that can be felt in the clutch pedal, mostly when stepped on.
5. The clutch disc surface is wavy
The clutch pedal's cause to vibrate when stepped on next is due to the clutch disc's surface that is wavy, uneven and shakes. Wavy surfaces on the clutch disc will vibrate when connected to the flywheel. As a result, these vibrations will also be felt and spread to the clutch pedal.
Many things can cause a wavy clutch disc: the clutch disc has been dropped before being installed or has been crushed by a heavier item so that the surface becomes uneven.
