Why Does the Clutch Disc of a New Car Burn Out?
2 Answers
As a wearing part, the clutch disc requires attention to its wear, which is largely related to usage habits. Working Principle: The clutch operates by separating and engaging the clutch disc to smoothly cut off and connect the engine power. The clutch disc is sandwiched between the flywheel and the pressure plate. Causes of Wear: Most damage to the clutch disc is caused by excessive temperature. Driving habits such as launch starts can easily lead to overheating of the clutch disc. Reasons for Overheating: Improper operation, such as partially engaging the clutch. Abruptly releasing the clutch pedal during driving causes the clutch disc and pressure plate to suddenly engage, which can easily lead to the decomposition of the clutch disc and wear of the pressure plate surface.
I've been driving for decades and have seen many cases of new cars burning out clutch plates, mainly due to poor driving habits. Novice drivers who are unfamiliar with the operation often keep the clutch partially engaged while stuck in traffic, which causes the clutch plate to generate heat through friction. When the temperature gets too high, it burns out. Another common cause is revving the engine too hard during takeoff, causing the plate to slip and overheat instantly. New cars are still in the break-in period, and the clutch plate isn't fully adapted yet. If you haul heavy loads or the car is fully loaded with passengers, the increased pressure makes it more prone to damage. It's advisable to develop good driving habits—shift to neutral in traffic, start gently, and avoid costly repairs. Safety comes first.
