On a long downgrade, how do the brakes function?

• A. They work as a supplement to engine braking
• B. They replace engine braking
• C. They are not used
• D. They have no effect

Answer: (A)

On a long downgrade, engine braking handles most of the slowing, but you still need the service brakes to supplement it. Downshift to a lower gear to maximize engine braking so the engine helps pull the speed down without overusing the wheel brakes. Use the brakes in short, controlled bursts to keep your speed within the safe range, and avoid riding them continuously because that can overheat and cause brake fade. The idea is to let the engine brake do the heavy work most of the time, then use the brakes to fine-tune your speed as needed.
