What happens to the brake linings during brake fade?

Answer: B — They lose their effectiveness with overheating

During brake fade, the brake linings experience a significant loss of effectiveness due to overheating. When brakes are applied repeatedly or with excessive force, the friction generated can increase the temperature of the brake components, including the brake linings. As these linings heat up, their material properties can degrade, which diminishes their ability to generate the necessary friction to slow down or stop the vehicle. This phenomenon is particularly concerning during long downhill drives or when the brakes are used continuously without sufficient cooling time, leading to a potentially dangerous situation where the driver may find it increasingly difficult to stop the vehicle. Understanding this process is crucial for maintaining safe braking performance and recognizing the signs of brake fade.
