What should you check about the brake pedal and its action during a cab inspection?
- A.The pedal should sink to the floor with almost no resistance
- B.A pedal that sticks down is helpful on long grades
- C.The pedal should feel firm and operate smoothly, with the brakes applying and releasing without sticking or delay
- D.Pedal feel does not matter as long as the gauges look normal
Correct answer
C. The pedal should feel firm and operate smoothly, with the brakes applying and releasing without sticking or delay
Why
Unusual pedal feel or slow release can reveal air delivery, valve, or mechanical problems before they show up in a hard stop. A brake that drags after release will also build heat and wear rapidly.
