What causes the clutch pedal of the Great Wall H6 to not return after being pressed down?

[LeSavannah]

Here are the reasons why the clutch of the Great Wall H6 does not return to its original position: Air in the clutch system: If there is air in the clutch fluid, it can cause the clutch to not return. In this case, the clutch fluid should be replaced, and the air in the clutch fluid line should be bled. Faulty return spring: Over time, the return spring may experience issues such as weakened elasticity or failure. The symptom is that there is no pressure when the clutch is pressed down. Clogged return oil hole: The return oil hole of the clutch oil pump may become clogged. This situation is mostly caused by poor quality clutch fluid with too many impurities, leading to clogging. The method to diagnose this is to open the engine hood and check the color of the fluid in the clutch fluid reservoir.
