Which statement about not relying on brakes on a long downhill is most accurate?

• A. It reduces fuel consumption
• B. It increases tire wear
• C. It can overheat brakes and reduce effectiveness
• D. It shortens stopping distance

Answer: (C)

On a long downhill you need to control speed without overheating the braking system. Relying on brakes continuously heats the brake components, and once they get too hot you experience brake fade—the pedal may feel soft and braking becomes less effective, which increases your stopping distance and the risk of losing control. Using engine braking by selecting a lower gear helps keep speed under control without building up excessive heat in the brakes. The best approach is to start in a lower gear before the descent and apply light, steady braking to maintain a safe speed, using the brakes only as needed and allowing them to cool if they start to get hot. This explains why the statement about not relying on brakes on a long downhill being able to overheat them and reduce effectiveness is the most accurate.
