Excessive heat in an air brake system can lead to brake fade, which is a significant reduction in braking performance. As brakes are applied, they generate friction, which turns into heat. When temperatures rise excessively, the brake components can become less effective, causing the brake pads or shoes to lose their ability to generate sufficient friction against the brake drum or rotor. This leads to a situation where the driver has to apply more pressure to achieve the same braking effect, which can be both dangerous and difficult to manage, especially during prolonged braking situations such as going downhill.

Understanding brake fade is crucial for maintaining safe vehicle operation, as it can impair a driver's ability to stop effectively in emergency situations. Recognizing the signs of overheating in a brake system is essential for preventative maintenance and ensuring the overall safety of the vehicle.
