The clutch disc is an important part of the clutch system. It is mounted on the clutch pressure plate and is connected to the flywheel of the engine. The clutch disc transmits engine power to the driveline by friction with the clutch pressure plate.

The clutch disc generally consists of a metal disk and a friction material (usually organic, metallic or ceramic). The friction material creates friction by rubbing against the flywheel, allowing engine power to be transmitted to the drivetrain. The clutch disc is also subjected to engine torque and pressure, so it needs to be durable and resistant to wear.

The degree of wear on the clutch disc depends on the conditions of use and the driving style of the vehicle. Frequent half-clutching, idling and high speed starting will accelerate the wear of the clutch disc. Therefore, reasonable driving habits and techniques are very important to extend the service life of the clutch disc.

If the clutch disc experiences excessive wear or other problems, such as surface abrasion, ablation or detachment, it is necessary to replace the clutch disc in a timely manner to ensure proper operation of the clutch system.
