Your brakes fade partway down a grade but the truck is still controllable. Which action can help the brakes recover?
- A.Ride the brakes lightly all the way down
- B.Pour water on the hot drums to cool them fast
- C.Stop in a safe place and let the brakes cool completely before continuing in a lower gear
- D.Speed up so airflow cools the drums
Correct answer
C. Stop in a safe place and let the brakes cool completely before continuing in a lower gear
Why
Faded linings regain friction as they cool, while continued use keeps them past the temperature where they can grip at all. Water on a hot drum can crack it, so time and air are the coolants, followed by a slower descent in a lower gear.
