What Causes the Squeaking Noise When Releasing the Clutch?
1 Answers
It is caused by poor lubrication, wear, looseness, or damage of the clutch release bearing. Lubricating oil needs to be added to the clutch release bearing or it should be replaced in time. Common clutch problems: 1. Clutch slipping: The free travel of the clutch pedal is too small, or the release bearing frequently presses against the diaphragm spring, keeping the pressure plate in a semi-engaged state. Alternatively, the clutch pressure plate spring may be too soft or broken, or the screws connecting the clutch to the flywheel may be loose. 2. Incomplete disengagement: When the engine is idling, the clutch can only be fully disengaged when the clutch pedal is pressed almost to the floor. If you feel difficulty shifting gears or hear a harsh gear clash, or if the vehicle starts moving without lifting the clutch pedal after shifting, these indicate incomplete clutch disengagement. 3. Testing pedal travel: The clutch should firmly engage when the pedal is pressed to about 3/4 of its travel. Otherwise, check if the pedal travel is appropriate. Use a ruler to measure the height of the pedal at its highest position and then measure the height when resistance is felt while pressing the pedal. The difference between these two values is the clutch pedal travel.
