How do you conduct a proper air brake system test?

To conduct a proper air brake system test, it is essential to perform both the service brake test and the static air loss test. This comprehensive approach ensures that the air brake system is functioning correctly in terms of both operational performance and maintaining adequate air pressure.

The service brake test checks whether the brake components engage and release properly under normal operation. This test is crucial for confirming that the truck can stop effectively and that the brake system will respond adequately when needed.

The static air loss test assesses the integrity of the air brake system by measuring how much air pressure is lost when the system is not in use. This test helps identify leaks or weaknesses that could compromise the system's reliability and safety.

Both tests are vital for ensuring that the air brake system is fully operational and can be trusted during driving conditions. Conducting only one of these tests or relying solely on visual inspections would not provide a comprehensive evaluation of the air brake system's performance or reliability. This detailed approach is necessary for maintaining safe operation on the road.
