When brakes fail on a downhill road and there is no usable terrain or opportunity, you should downshift gear by gear or quickly skip one gear, using engine braking to control speed.

ANSWER · A

When the foot brake fails 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 drag reduces the load on the brakes and the number of applications, preventing thermal brake fade. On icy, snowy, or muddy roads, engine drag braking helps prevent skidding.
