What are the reasons why the car clutch does not return after being pressed down?
1 Answers
Car clutch does not return after being pressed down for the following reasons: Air in the clutch hydraulic system: Air in the clutch hydraulic system causes excessive clutch travel and poor return. This type of fault can be self-diagnosed: when the clutch pedal is pressed for the first time, it feels like there is no resistance and the travel is excessive. After repeatedly pressing the clutch pedal, the pedal rises, mostly due to air entering the hydraulic system. In this case, the cause of the air entry should be identified as soon as possible, and the air in the hydraulic system should be expelled. Contaminated clutch fluid: Dirty clutch fluid with impurities causes severe wear of the internal piston of the clutch master cylinder or blockage of the return oil hole, preventing the clutch from returning. Open the engine hood and check if the fluid in the clutch fluid reservoir appears black or gray. If discolored, the clutch fluid should be replaced promptly. Insufficient spring tension: As the vehicle mileage increases, the clutch return spring may lose tension or break, causing the clutch pedal not to return. The symptom of this fault is a reduced clutch pedal height and decreased or no free play. Clutch wear: Excessive wear gap in the clutch linkage push rod causes poor return. This type of fault requires replacement of the clutch master cylinder or linkage mechanism.
