What should a driver check about air hoses during a pre-trip inspection?
- A.That hoses are painted the same color as the truck
- B.That hoses are as loose as possible for flexibility
- C.That hoses are not cracked, cut, chafed, leaking, or dragging, and that connections are secure
- D.That hoses carry no air when parked
Correct answer
C. That hoses are not cracked, cut, chafed, leaking, or dragging, and that connections are secure
Why
Air hoses fail from rubbing, heat, and age, and a burst hose can cost a whole circuit. Listening for leaks and looking for wear through the outer cover are key parts of the brake inspection.
