What happens if the clutch disc is not replaced?
It will damage the flywheel and make it impossible to drive properly
The life of the clutch plate is the same as that of the brake pad, which varies from person to person, depending on driving habits. Some good, hundreds of thousands of kilometers do not need to change, some open fierce, there may be tens of thousands of kilometers to replace.
The clutch disc and the engine flywheel are a bit like the relationship between the brake disc and the brake pad, rubbing against each other. The brake discs are not worn off. It's no use having them.
