Question: 1 / 400

What should the brake chamber be checked for during a pre-trip inspection?

Heavy oil presence

Audible leaks

During a pre-trip inspection, the brake chamber should be checked for audible leaks because these leaks can significantly impact the braking system's performance. An audible leak indicates that there is air escaping from the brake chamber, which can lead to insufficient air pressure for effective braking. If the brake chamber cannot maintain the required air pressure, it may not activate the brakes properly, resulting in decreased stopping power and creating a serious safety hazard.

Listening for leaks allows the inspector to ensure that the air brake system is functioning correctly before starting the journey. Properly sealing brake chambers are critical for the efficiency and safety of the vehicle's braking system. Detecting any audible leaks during the inspection process ensures that necessary repairs can be performed before the vehicle is on the road, enhancing overall safety.
