Brake fade is commonly caused by overheated brakes. This phenomenon occurs when the brake system is subjected to excessive heat, which can reduce the friction between the brake pads and the rotors, leading to diminished braking performance. When brakes are applied repeatedly or held for extended periods, such as when driving downhill or during heavy braking, the heat generated can exceed the ability of the brake system to dissipate it. As a result, the effectiveness of the brakes diminishes, which can lead to longer stopping distances and increased difficulty in slowing down or stopping the vehicle securely.

In contrast, while under-inflated tires, high-speed driving, and poor road conditions can contribute to overall vehicle instability and performance issues, they do not specifically lead to the overheating of brakes that characterizes brake fade. Proper brake maintenance and awareness of braking techniques are essential for preventing brake fade and ensuring safe operation of commercial vehicles.
