With overheating of the brakes the braking performance:

Explanation

Correct answer: may decrease.

Overheating of the braking system, which often occurs during prolonged braking on downhill slopes, causes a decrease in the coefficient of friction between the friction elements (brake pads and discs). This phenomenon, known as 'brake fade', leads to a significant reduction in braking force. As a result, the distance required to stop the vehicle increases dangerously, and the effectiveness of the brakes decreases.
