When you inspect rubber air hoses for the service brakes, which condition should be reported as a defect?

• A.A hose that is cracked, cut, bulging, or worn through from rubbing
• B.A hose that is routed in a gentle curve with no sharp bends
• C.A hose that is clean and firmly attached at both ends
• D.A hose that flexes slightly when air pressure is applied

Why

Air hoses must be secure and free of cracks, cuts, bulges, and chafing damage that could open under pressure. A failed hose can dump air quickly and leave that part of the brake system without enough pressure to work.
