What Causes the Noise When Pressing the Clutch Pedal?
2 Answers
There are several reasons why the clutch makes noise when pressed: 1. Broken drive plate steel sheet: A sharp noise is heard when the clutch is about to engage. The sound disappears when the pedal is pressed and reappears when the pedal is released. This is caused by a broken drive plate steel sheet or exposed rivet heads scraping against the pressure plate or flywheel, requiring major repairs. 2. Lack of lubrication in the release bearing: When there is insufficient lubricating oil, the balls inside squeeze against each other, producing abnormal noise, or the balls may become deformed. 3. Stagnation in the linkage system, deformation of the drive plate, or oil contamination on the friction disc: Symptoms include the clutch pedal being lifted at low speed, the vehicle jerking when starting, and a "bang" sound being emitted.
I used to encounter this situation frequently. The sound when pressing the clutch is usually caused by a problem with the release bearing. When the bearing ages and wears out, it produces a squeaking noise. Another possible reason is the friction noise caused by worn clutch discs. Recalling the last time I had my car repaired, I noticed that the sound getting louder meant the bearing was about to fail. If left unaddressed, the clutch could completely malfunction, affecting driving. I recommend going to a professional repair shop as soon as you hear any abnormal noise and having them check the entire clutch system for any looseness or improper assembly. During regular maintenance, you can also ask the technician to help clean the clutch dust to extend its lifespan. Safety is the top priority.
