What Causes the Clutch Not to Return?

[Laurie]

The reasons for the clutch not returning include: air entering the clutch pipeline system, and dirty clutch fluid with impurities. Air entering the clutch pipeline system: Air entering the 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, if there is no resistance and the travel is excessive, and the pedal rises after repeated pressing, it is 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 purged. Dirty clutch fluid with impurities: Impurities can cause severe internal wear of the clutch master cylinder or clog the return oil hole, preventing the clutch from returning. You can open the engine hood to check if the fluid in the clutch fluid reservoir appears black or gray. If discolored, the clutch fluid should be replaced promptly.
