What is the primary cause of clutch fade?

Clutch fade primarily occurs when the clutch disc and pressure plate experience overheating due to excessive slipping. When the clutch is not fully engaged or is engaged too slowly, it generates friction, which produces heat. If the heat generated exceeds the component's design limits, it can lead to a reduction in friction material's effectiveness, resulting in clutch fade. This condition causes the clutch to lose its ability to transmit power effectively, leading to a spongy or unresponsive clutch pedal feel during operation.

Proper engagement of the clutch is critical for avoiding this overheating, and it emphasizes the importance of operating the vehicle within the recommended gear ranges and avoiding prolonged slipping situations. While improper gear selection, lack of lubrication, and a worn clutch plate can influence the performance and lifespan of the clutch, they do not directly cause the immediate phenomenon of clutch fade to the extent that overheating does.
