When descending a steep grade, brake fade poses a significant risk as it can lead to a loss of all control over the brakes. Brake fade occurs when the braking system overheats due to prolonged or excessive use, diminishing its effectiveness. This is particularly critical in steep descents, where maintaining speed control is vital to ensure safety and prevent accidents. As the brakes heat up, the brake fluid can boil, and the friction material on the brake pads may lose its grip, resulting in decreased stopping power.

This can make it difficult or impossible to slow down or stop the vehicle effectively, increasing the likelihood of a collision or loss of vehicle control. Therefore, awareness and management of brake fade are essential when driving in hilly or mountainous terrain, making it imperative for drivers to understand and recognize this risk during steep descents.
