What can cause brake fade in a trucking system?

Brake fade occurs when the braking system loses its effectiveness due to the overheating of brake components. This heat build-up can cause the braking surfaces, such as the brake pads and rotors, to lose their grip, resulting in a longer stopping distance and reduced braking power. When brakes are applied repeatedly or for extended periods, such as during long downhill descents or in stop-and-go traffic, the friction created generates significant heat. If the heat exceeds the design limits of the brake components, it can lead to thermal degradation of the friction material, gas formation between the pad and rotor, or warping of components, all of which contribute to brake fade.

While excessive weight load, faulty brake pads, and incorrect tire pressure can contribute to other brake issues or tire performance concerns, they do not directly cause the phenomenon of brake fade in the same manner as overheating. Understanding the role of heat management in braking systems is crucial for preventing brake fade and ensuring safe vehicle operation.
