What is the recommended way to work the brake pedal while descending a steep grade?
Correct answer: Slow to 5 mph under the safe speed, let up, and brake again on reaching the safe speed.
Answer options
- ASlow to 5 mph under the safe speed, let up, and brake again on reaching the safe speed Correct
- BHold light, steady pressure on the pedal the whole way from the top of the grade to the bottom
- CPush the pedal harder and harder as the vehicle rolls farther down the grade, never letting up
Why
This snub-braking method keeps the brakes from overheating and fading: with the engine doing most of the work in a low gear, brake firmly enough to feel a clear slowdown, let off once you are roughly 5 mph under your safe speed, and brake again when you are back up to the safe speed. Constant or ever-increasing pressure heats the brakes until they fade.
