What is the reason for the Roewe 350 clutch not springing back?

[MacSadie]

The main reasons for the clutch not springing back are air entering the clutch pipeline system and dirty clutch fluid with impurities. The specific explanations are as follows: 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. If the first press of the clutch pedal feels without resistance and the travel is excessive, and the pedal rises after repeatedly pressing it, 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 expelled. Dirty clutch fluid with impurities: Impurities cause severe internal wear of the clutch master cylinder or blockage of 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.
