What should a driver do if they notice brake fade?

Answer: B — Pull over and let the brakes cool

When a driver experiences brake fade, it indicates that the brakes are losing effectiveness due to overheating. This situation often occurs after prolonged or excessive braking, which can cause the brake components to lose their grip and functionality. The recommended action in this scenario is to pull over and let the brakes cool. Allowing the brakes to cool is crucial because the braking system can regain its effectiveness when it is no longer subjected to continual heat. This procedure helps ensure the safety of both the driver and others on the road. Attempting to apply the brakes harder or increasing speed would exacerbate the problem, leading to further overheating and potential brake failure. Ignoring the issue and continuing to drive poses significant risks, as diminished braking power could result in inability to stop effectively. Therefore, the best practice when noticing brake fade is to safely pull over and allow the brakes to cool down.
