What is the problem when the clutch pedal does not return after being pressed?

[LaJulia]

The reasons why the clutch pedal of a car does not return after being pressed are as follows: 1. Air enters the clutch pipeline system, causing excessive clutch travel and poor return. This fault can be self-diagnosed. When the clutch pedal is repeatedly pressed, the pedal will rise. Most of the time, this is due to air entering the hydraulic system. In this case, the cause of the air entry should be identified and repaired as soon as possible. 2. The clutch fluid is dirty with impurities, causing severe wear of the internal piston of the clutch master cylinder or blockage of the return oil hole, resulting in the clutch not returning. 3. As the vehicle mileage increases, the clutch return spring loses its elasticity or breaks, causing the clutch pedal not to return. 4. Excessive wear gap of the clutch linkage push rod causes poor return.
