On a long, steep downgrade, which braking method should you use?
Correct answer: Brake until you are 5 mph under the safe speed, release the brakes, and brake again once you are back at the safe speed.
Answer options
- ALet your speed build to 5 mph over the safe speed, then brake until you are back down at the safe speed, and repeat
- BBrake until you are 5 mph under the safe speed, release the brakes, and brake again once you are back at the safe speed Correct
- CBrake until you are down to 5 mph, release the brakes, and brake again once you are back at the safe speed
Why
Press the brakes hard enough to feel a definite slowdown, let off once you are 5 mph under the safe speed, and brake again only after speed has climbed back to it. Brief, separate applications like this keep the brakes from overheating and fading.
