When brakes fail downhill, downshift quickly one gear at a time or skip a gear, and use engine braking to control speed.

ANSWER · A

When brakes fail downhill, downshift quickly (you may skip one gear, but not two), and use engine braking to slow down and stop. Engine braking uses the engine's drag to slow the vehicle. The lower the gear, the stronger the drag and the braking effect. On long downhill stretches, shifting to a lower gear and using engine braking reduces the load on the brakes and the number of brake applications, preventing brake fade from overheating. On icy or muddy roads, engine braking helps prevent skidding.
