Operation & Safety第 50 / 60 题
What is the proper braking technique (snub braking) on a long downgrade?
a.Hold steady light pressure the entire way down
b.Coast in neutral and brake only at the bottom
c.Never touch the brakes at all
d.Apply the brakes firmly to slow about 5 mph below your safe speed, then release, and repeat
解析
With the vehicle in a low gear, apply the brakes firmly enough to feel a definite slowdown, then release when your speed has dropped about 5 mph below your safe speed. Once speed climbs back to the safe speed, repeat the process. This snub-braking method keeps the brakes from overheating compared with light, constant pressure.
