Clutch is a kind of friction as the main feature, both composite structural performance requirements. Automotive friction materials are mainly used to manufacture brake linings and clutch plates. The main use of asbestos friction material friction material, along with environmental and safety requirements are high, the gradual emergence of a semi-metallic friction materials, composite fiber friction materials, ceramic fiber friction materials. Since the friction material in the car is mainly used in the manufacture of the brake system and drive train components, requires a sufficiently high and stable coefficient of friction and good wear resistance. In use will gradually wear, when worn to the limit position must be changed, otherwise it will reduce the braking effect, and even cause accidents. Under normal circumstances the clutch disc front brake shoe wear relatively quickly, the time to use the rear brake shoe is relatively long. Paul raised in the daily, it should be noted: Under normal driving conditions, driving 5000 km per piece for car inspections, not only to check the remaining thickness, also check the status of shoe wear, whether the degree of wear on both sides of the same, whether return freely, etc., found irregularities must be dealt with immediately, clutch friction material must not be such as wear parts are not the only replacement.
