During an air brake check, which of the following must also be examined?

1. tire pressure

2. battery condition

3. brake drums, linings, and hoses

4. vehicle headlights

The correct answer is: brake drums, linings, and hoses

The correct answer focuses on the critical components of the braking system that directly impact a vehicle’s safety and operation. During an air brake check, it is essential to examine brake drums, linings, and hoses because they are crucial to the proper functioning of the air brake system. The brake drums provide the surface against which the brake linings press to create the necessary stopping force, while the hoses are vital for transporting compressed air from the tank to the brake mechanisms, ensuring that the brakes can be applied effectively. A thorough inspection of these components can help identify wear and tear, air leaks, or other issues that could lead to brake failure. Consequently, understanding the condition of these elements is imperative for the safe operation of a vehicle equipped with air brakes. Regular checks enhance overall vehicle safety and efficiency, making this task a vital part of pre-trip inspections or routine maintenance.
