What Causes the Abnormal Noise When Depressing the Clutch in a Sedan?

[OLaila]

The reasons for abnormal noise when depressing the clutch in a sedan are as follows: Clutch Release Bearing: After wading through water, the release bearing may get water inside, leading to loss of lubricant, rust, dry friction, and other factors that can cause damage to the release bearing. Lack of Lubricant: The return spring of the clutch pedal lacks lubrication oil. Clutch Disc Wear: During driving, after shifting gears, if the clutch pedal is not fully released, the clutch disc and the clutch pressure plate cannot fully engage, causing mutual friction and abnormal wear of the clutch disc. Clutch Pressure Plate Spring Breakage: The spring inside the clutch disc is called a damping spring. The clutch, as a critical component in the drivetrain for transmitting engine torque, can suffer damage due to instantaneous impact loads caused by torsional vibrations in the drivetrain from engine torque variations, rapid clutch release, or emergency braking.
