How is brake heat dissipated?

The dissipation of brake heat primarily occurs through the metal brake drums or rotors. When brakes are applied, friction is generated between the brake pads and the drums or rotors, creating heat. The metal components have a high thermal mass, which allows them to absorb and store a significant amount of this heat energy during braking. This process of heat absorption helps to prevent the brake system from overheating, which could lead to brake fade or failure.

While the brake fluid does play a role in transferring force from the brake pedal to the brake components, it is not responsible for dissipating heat. Air flow around the brakes can assist in cooling to some extent, but the primary mechanism of heat dissipation is through the absorption by the metal itself. Tire rotation is not a significant factor in heat dissipation related to brakes; instead, rotating tires facilitate vehicle movement and traction. Understanding the role of brake components in managing heat is crucial for maintaining vehicle safety and performance.
