What Causes the Squeaking Sound When Pressing and Releasing the Clutch?

[CarterLee]

When pressing the clutch, abnormal noises mainly occur during engagement or disengagement. The most common cause is a lack of lubrication in the clutch pedal's return spring. Below is an introduction to the clutch: Introduction: The clutch is located inside the flywheel housing between the engine and the transmission. The clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. Function: While driving, the driver can press or release the clutch pedal as needed to temporarily disconnect or gradually engage the engine and transmission, thereby cutting off or transmitting the engine's power to the transmission. The clutch is a common component in mechanical transmissions, allowing the drivetrain to be disconnected or engaged at any time. Basic requirements for the clutch: smooth engagement, quick and thorough disengagement; easy adjustment and repair, compact size; lightweight; good wear resistance and sufficient heat dissipation capacity.
