What is the reason why the clutch pedal of Changan CS75 cannot be lifted after being pressed down?
1 Answers
Changan CS75 clutch pedal cannot be lifted after being pressed down due to air in the pipeline system, dirty oil with impurities, or insufficient spring elasticity. Air in the clutch pipeline system: It will cause excessive clutch travel and poor return. When the clutch pedal is pressed for the first time, it feels no resistance and the travel is too large. After repeatedly pressing the clutch pedal, the pedal rises, which is mostly caused by air entering the hydraulic system. At this time, the cause of the air entering should be found as soon as possible and the air in the hydraulic system should be discharged. Dirty clutch oil with impurities: It will cause severe wear of the internal piston of the clutch master cylinder or blockage of the return oil hole, resulting in the clutch not returning. You can open the engine hood to check whether the oil in the clutch oil reservoir is black-gray. If the color changes, the clutch oil should be replaced in time. Insufficient spring elasticity: With the increase of vehicle mileage, the insufficient elasticity of the clutch return spring causes the clutch pedal not to return. The fault phenomenon is that the height of the clutch pedal decreases and the free clearance decreases or disappears. The spring should be replaced in time to prevent accidents.
