What is the most important habit that prevents brake failure emergencies on mountain grades from developing at all?
- A.Descending in the highest gear to reduce engine wear
- B.Saving the brakes by never testing them at the summit
- C.Selecting the proper low gear before the descent and using snub braking and retarders to keep service brake use light from the start
- D.Using the service brakes continuously so they stay warm
Correct answer
C. Selecting the proper low gear before the descent and using snub braking and retarders to keep service brake use light from the start
Why
Most downgrade failures are built at the top of the hill by a gear choice that was too high and braking that never gave the drums a rest. Prevention is routine, while the ramp is the admission that prevention was skipped or the equipment failed anyway.
