Home › CDL Practice Tests › Air Brakes Questions › Question 184
Which sign suggests your brakes are overheating on a descent?
- A.Smoke, a strong burning smell, or noticeably weaker slowing for the same pedal application
- B.A cooler feel through the pedal
- C.The air gauge rising above its normal range
- D.Quieter operation than usual
Correct answer
A. Smoke, a strong burning smell, or noticeably weaker slowing for the same pedal application
Why
Smoke and odor mean lining material and nearby parts are being cooked beyond their intended temperature. Weak response at the same time is fade arriving, and it calls for stopping and cooling rather than more pedal pressure alone.
