The clutch has friction plates on the pressure plate like the brakes on the wheels, which are made of wear-resistant asbestos and copper wire. The friction plates on the pressure plate also have the minimum allowable thickness. After running for a long time, the friction plates on the pressure plate need to be replaced The original factory can replace the friction plates by purchasing and replacing the parts themselves. You can buy the installed friction plate assembly without replacing the friction plates by yourself and directly replace the clutch pressure plates In order to reduce clutch loss, there is a correct way to use clutch pedal Don't half step on the clutch pedal So that the clutch disc is in a semi-clutch state, that is, the Frisbee and the pressure plate are in friction state When the clutch pedal is fully depressed, the flywheel and clutch pressure are completely cut away without friction between them If the clutch pedal is fully lifted, the flywheel and the clutch pressure plate are fully engaged, where there is friction but basically no friction So the clutch pedal can't step on half of the state
