What should you look for when inspecting the school bus's brakes?

When inspecting a school bus's brakes, it is crucial to listen for any unusual noises and to test for adequate stopping power. This aspect of inspection is vital for ensuring the safety of the bus, as the braking system is essential for stopping the vehicle effectively and efficiently. Unusual noises can indicate potential issues such as worn brake pads, air leaks in air brake systems, or problems with brake components that may compromise performance and safety.

Testing for adequate stopping power involves evaluating how well the brakes engage and slow the bus down under normal and emergency conditions. This ensures that the bus can stop quickly when needed, safeguarding the passengers and other road users.

Focusing on these elements during the inspection directly relates to the operational safety of the bus, which is why this choice is the correct one. Other options like checking for decorative stickers, ensuring bright colors, or looking for brand names do not contribute to the functional assessment of the braking system and, therefore, do not address the critical safety requirements necessary for operating a school bus.
