What to Do When the Clutch Pedal Feels Heavy?

[VanEmery]

Heavy clutch pedal may be caused by faults in the clutch pressure plate, clutch disc, or release bearing. Here is an analysis of the reasons for a heavy clutch: Damaged Clutch Cable: A damaged clutch cable increases friction resistance, making the clutch pedal feel heavy. In this case, it is recommended to replace it directly rather than attempting lubrication with oil. Worn Clutch Disc: The clutch disc is sandwiched between the pressure plate and the flywheel, with the clamping force provided by the diaphragm spring of the pressure plate. Greasing the Release Bearing Seat: There is minimal friction between the release bearing and its seat, so additional lubrication is unnecessary. Moreover, the clearance between the release bearing and its seat is relatively small, and grease tends to be sticky, which can increase resistance. Especially when the clutch disc operates, it generates a lot of dust that sticks to the grease, making it even stickier and harder. This can cause the clutch to feel heavy.
