What is the snub braking technique for controlling speed on a downgrade?
- A.Riding the brakes lightly the whole way down
- B.Braking only at the very bottom of the hill
- C.Apply the brakes firmly enough to slow about 5 mph below your safe speed, release, and repeat as speed builds again
- D.Pumping the pedal as fast as possible
Correct answer
C. Apply the brakes firmly enough to slow about 5 mph below your safe speed, release, and repeat as speed builds again
Why
Snub braking alternates firm applications with full release, giving the brakes cooling time between applications. Dragging the brakes continuously is what overheats them into fade.
