Hello Teacher Xiong! A small van I have maintained，The owner said that after the overhaul clutch in other repair shops，The vehicle becomes very heavy after a few days of use，Now go to my factory for maintenance。I think of my previous sedan encounteredClutch pedalWhen a heavy failure，Consult you，It will be better if you replace the three -piece set。This time I changed the clutch film、Platter Pressing Disk、Clutch separation bearing，Lubricated the clutch separation and the fork，But there is seabet myno improvement at all，Is there any other cause of failure?
