How should a driver respond to brake fade?

Reducing speed and using lower gears is the correct response to brake fade because it effectively addresses the loss of braking power that occurs when brakes overheat and become less effective. Brake fade typically happens during prolonged braking, such as when descending a steep hill or during heavy stop-and-go traffic. By reducing speed, the driver decreases the need for excessive braking, allowing the brakes to cool down and regain some of their effectiveness.

Using lower gears helps the vehicle maintain better control despite diminished braking power. This technique leverages engine braking to assist in slowing down the vehicle, which can be particularly useful in maintaining a safe speed while navigating down a hill or any incline. It can also help alleviate some of the demands on the brake system, further helping to mitigate the effects of brake fade.

The other options do not effectively address the situation. Accelerating would worsen the loss of control, increasing brake pressure is pointless if the brakes are already fading, and switching exclusively to engine braking without slowing down may not adequately reduce speed if the brakes are necessary for stopping entirely.
