Which components should be checked during a pre-trip air brake inspection?

• A. Seat belt, horn, lights, and mirrors.
• B. Air tanks, lines, hoses, governor, valves, and the warning devices.
• C. Battery, alternator, starter, and fuse box.
• D. Radiator, coolant, radiator cap, and thermostat.

Answer: (B)

During a pre-trip air brake inspection, you’re checking the parts that create, store, and manage the air pressure that operates the brakes. The air tanks, lines and hoses, the governor that controls when the compressor cycles, the various valves that regulate airflow, and the warning devices are all essential because they must be secure, free from leaks, and functioning properly. If any of these components fail or there’s a leak, you could lose braking power or fail to get an important low-pressure warning, which is dangerous on a heavy vehicle. The other systems mentioned—such as seating and interior safety items, electrical components, or the cooling system—aren’t part of the air brake pre-trip inspection. So, focusing on air tanks, lines, hoses, the governor, valves, and the warning devices correctly targets the air brake system.
