introduction： Problem between clutch pressure discs The wearing part of the clutch is the clutch disc，Pressure plates are generally not easily damaged。Pressure plate damage is mainly caused by pressure plate ablation，Surface hardening，Causing the clutch to slip。There are also pressure plate cracks、Severance、inequality，Can cause a skid，inseparability，shiver、Power transmission is poor、Abnormal noise。Nowadays cars are mostly diaphragm spring clutches，The pressure plate is integrated with the back cover，Once the platen is damaged，We need to change the assembly.。

introduction： Locking or biting often occurs in stainless steel，Aluminum alloy and titanium alloy materials on fasteners，These metal alloys are inherently corrosion resistant，When the surface is damaged，A thin oxide layer is created on the metal surface to prevent further corrosion。When stainless steel fasteners are locked，The pressure and heat generated between the teeth breaks down this oxide layer，Cause to block or shear between metal threads，Then the phenomenon of adhesion occurs。When this phenomenon continues to occur，The stainless steel fasteners will lock completely，Can no longer be removed or relocked。Usually this
