What can excessive heat in the braking system lead to?

Excessive heat in the braking system can significantly impair its performance, primarily leading to brake fade and rotor warping. When brakes are applied, friction generates heat, which is necessary for their operation. However, if the brakes overheat due to prolonged use or inadequate cooling, the brake fluid can boil, causing a loss of hydraulic pressure. This results in brake fade, where responsiveness diminishes and the vehicle may not stop as effectively.

Furthermore, high temperatures can cause the brake rotors to warp. This warping occurs because the metal can expand unevenly under heat, leading to irregular surfaces that compromise the even contact between the brake pads and rotors. This not only affects braking performance but can also create vibrations and noise while braking.

Improved braking efficiency, increased brake pad lifespan, and reduced stopping distances are typically associated with optimal functioning of the braking system. However, excessive heat detracts from these desired characteristics, making it crucial to manage brake temperatures to ensure safe and effective braking performance.
