How can high temperatures affect brake performance?

High temperatures can significantly impact brake performance, leading to a phenomenon known as brake fade. As the brakes are applied, the friction generated between the brake pads and the rotors produces heat. If the temperature becomes excessively high, it can cause a reduction in the friction material's effectiveness, resulting in diminished stopping power and responsiveness.

Brake fade occurs as the high heat can lead to gas buildup between the pads and the rotors or can cause the brake pads to overheat, losing their ability to grip effectively. This leads to a longer stopping distance and can be particularly dangerous in high-demand situations such as downhill braking or repeated heavy braking.

Understanding this effect is crucial for vehicle handling and safety, as it underscores the importance of adequate brake cooling and the selection of suitable brake materials designed to withstand high temperatures.
