What Causes Abnormal Noise When Depressing the Clutch?

[DiHector]

Abnormal noise when depressing the clutch can be caused by: 1. Loose release bearing; 2. Lack of lubricant; 3. Worn clutch disc; 4. Broken clutch pressure plate spring. Solutions for abnormal noise when depressing the clutch include: 1. Replace the clutch disc; 2. Replace the clutch pressure plate spring; 3. Adjust the release bearing; 4. Add lubricant. The working principle of the clutch is: 1. When starting the vehicle, the driver depresses the clutch, separating the pressure plate from the friction disc, at which point the pressure plate and flywheel are not in contact; 2. During normal driving, the pressure plate is tightly pressed against the flywheel's friction disc, creating significant friction between them, maintaining relative static friction between the input and output shafts, which then rotate at the same speed.
