Excessive heat buildup in brakes primarily leads to brake fade and possible failure. Brake fade occurs when the brake components become too hot, which reduces their effectiveness. This is due to the deterioration of the friction material's ability to create grip with the brake disc or drum as temperatures rise. As the temperature increases, the braking system can reach a point where it struggles to properly generate the friction needed for effective stopping power, which can lead to longer stopping distances and a complete loss of braking ability if temperatures exceed the component's thresholds.

The other options do not accurately reflect the consequences of excessive heat in the braking system. For example, while braking torque is important for deceleration, excessive heat doesn't increase it; instead, it compromises the overall effectiveness. Enhanced brake grip would actually be the opposite effect of what occurs with heat buildup. Additionally, reduction in rotor size is not a direct consequence of heat but rather a design factor; heat can cause warping or deterioration, but it does not physically reduce the rotor's dimensions.
