What Causes Abnormal Noise When Depressing the Car Clutch?
2 Answers
Here are the main reasons for this situation: 1. The clutch pressure plate spring is broken or the release bearing is loose. 2. The clutch disc is cracked. 3. The clutch release lever is broken, excessively worn, or the release lever adjustment bolt is broken. Here is some relevant information about the clutch: 1. Keeping your foot on the clutch pedal for extended periods while driving can easily lead to clutch slippage, clutch disc burning, and in severe cases, even cause the clutch pressure plate and flywheel end face to burn and wear, resulting in issues like the clutch pressure spring losing its temper. 2. When shifting gears while driving, the clutch pedal should be depressed and released quickly, avoiding partial engagement. Otherwise, it will accelerate clutch wear.
I've been driving a taxi for almost twenty years and have encountered clutch noise issues many times. The most common problem is the release bearing failing, which causes squeaking or rattling sounds when you press the pedal, especially in older cars. Sometimes, it's just the clutch linkage or pedal pivot pin lacking lubrication, creating a dry grinding noise—a quick spray of lubricant can fix that. Other times, it's the clutch disc springs becoming loose or broken, resulting in a clicking sound when pressed. For cars with hydraulic systems, leaks in the master or slave cylinder can produce a hissing noise. I recommend addressing it early. Once, a customer ignored it until the car broke down midway, ending up spending over two thousand to replace the entire clutch—totally not worth it. Regular driving habits like avoiding riding the clutch and periodic fluid checks can extend component lifespan.
