While inspecting the brake chambers and connected air lines at each axle, which condition indicates an immediate safety defect?
- AManual slack adjuster pushrods that move approximately one-half inch when pulled by hand with brakes released
- Air supply hoses that are cracked, worn through outer protective layers to the cord, or audibly leakingCevap
- CBrake chambers securely mounted with intact clamp rings and clearly legible identification stampings
- DPushrods that show zero movement when checked while the spring parking brakes remain fully applied
Cevap
Air supply hoses that are cracked, worn through outer protective layers to the cord, or audibly leaking
Air lines and brake hoses must be checked for cracks, chafing, cuts, and leaks. Hoses worn down to the reinforcing fabric or leaking air cannot safely maintain operating pressure and are out-of-service safety violations.
