Why Doesn't the Clutch Pedal Return When the Car is Hot?
1 Answers
The reasons why the clutch pedal does not return after being depressed are as follows: 1. Air has entered the clutch hydraulic system, causing excessive clutch travel and poor return. You can diagnose this issue yourself: If the first time you press the clutch pedal, it feels like there is no resistance and the travel is excessive, and the pedal rises after repeatedly pressing it, it is likely due to air entering the hydraulic system. In this case, you should quickly identify the cause of the air ingress and bleed the hydraulic system. 2. The clutch fluid is dirty or contains impurities, causing severe wear of the clutch master cylinder (piston) or blockage of the return oil hole, preventing the clutch from returning. You can 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. 3. As the vehicle's mileage increases, the clutch return spring may lose its elasticity or break, causing the clutch pedal not to return. The symptoms of this fault are a lowered clutch pedal height and reduced or no free play. 4. Excessive wear of the clutch linkage push rod leads to poor return. This type of fault requires replacing the clutch master cylinder or linkage mechanism.
