What Causes the Friction Sound When Pressing the Clutch?
2 Answers
The friction sound when pressing the clutch is caused by incomplete clutch disengagement. The solution is for the owner to adjust the free travel of the clutch pedal. When encountering abnormal noises, the owner should not panic excessively but maintain a safe distance from the vehicle ahead, park the car in an appropriate location, engage the parking brake, place wheel chocks, and shift the transmission into neutral. There are two scenarios that can cause abnormal clutch noises: 1. After shifting gears, if the foot continues to press on the clutch pedal, maintaining this habit for a long time can damage the clutch and wear out the clutch disc. Such noises are often due to issues with the clutch release bearing. 2. When pressing the clutch pedal, a distinct abnormal noise can be heard from the clutch area, which becomes more noticeable upon releasing the pedal. This could be due to a broken clutch pressure plate spring, a loose release bearing, a shattered clutch disc, a broken or excessively worn clutch release lever, or a faulty adjustment bolt. These issues typically indicate quality problems with the clutch release bearing.
When stepping on the clutch, I hear a friction sound, which I've also encountered in other cars I've driven. It's most likely due to a faulty clutch release bearing. This component is inside the clutch and rotates when we press the clutch pedal to ensure smooth gear shifting. Over time, the bearing can wear out or lack lubrication, resulting in that squeaking or grinding noise. It could also be caused by issues with the clutch master cylinder or pressure plate, such as improper installation or lack of oil. If you notice the sound getting louder, driving may feel harder when shifting gears, or even lead to complete clutch failure, which can be dangerous. I recommend not pushing your luck and heading to a repair shop for a check-up as soon as possible. They can diagnose it with simple tools and fix it early. Regular maintenance of the clutch system, such as adding lubricant, can help reduce such troubles.
