What is a potential consequence of brake fade?

Brake fade is a phenomenon that occurs when the brakes become less effective due to overheating. When brakes are applied repeatedly or for prolonged periods, such as going downhill or during heavy braking, the heat generated can lead to a decrease in the braking force. This is primarily due to the deterioration of braking materials or the performance characteristics of the brake fluid, resulting in a significant reduction in stopping power.

This reduced stopping ability can be dangerous, as it may lead to longer stopping distances or even an inability to stop in emergency situations. It's essential for drivers, especially those operating vehicles with air brakes, to recognize the signs of brake fade and take necessary precautions, such as allowing brakes to cool down or using lower gears to reduce reliance on braking. Understanding this aspect of brake operation ensures that drivers are prepared and can maintain control of their vehicle in various driving conditions.
