Question:

When traveling down a steep downgrade, the best way to use your brakes is to

A Apply the brakes for a few seconds, then release the brakes for a few seconds. Continue to repeat these steps as you travel down the hill

Explaination

On a long or steep downgrade, brakes should only be used to supplement the braking effect of the engine. Apply the brakes just enough to feel a definite slowing down, then release them once you are about five mph below your target "safe" speed. Once your vehicle reaches its safe speed again, repeat this process.
