What should you do to test the air service brakes?

Brake firmly while slowly moving forward
Apply the brakes rapidly
Coast to a stop without braking
Brake gently while accelerating

The correct answer is: Brake firmly while slowly moving forward

To test the air service brakes, the appropriate method is to brake firmly while slowly moving forward. This action allows the driver to evaluate the brakes' responsiveness and effectiveness under actual conditions. When applying the brakes firmly at a low speed, it provides a clear indication of how well the brakes function without subjecting the vehicle to any abrupt demands or risks of losing control. By performing this test at a low speed, you can better assess for any issues, such as delayed response or unusual noises, which might indicate maintenance is needed. This approach ensures that the driver can safely determine the condition of the brakes before engaging in higher-speed driving or on-road conditions. In contrast, applying the brakes rapidly may not give a true reflection of brake performance and could lead to loss of control. Coasting to a stop without braking does not offer any assessment of the brake system, and braking gently while accelerating does not adequately test the brakes' stopping capability.
