System air leak test:
The standard test that Newell uses for the air system is to bring the air system up to the point where the 120 volt air compressor cuts off (typically about 90-95 psi) and see how long it takes for the air system to leak down enough for the air compressor to cycle back on (typically about 70-75 psi). The 120 volt air compressor should have about a 20 psi difference between cycle on and cycle off. If the system leaks down in less than 40 minutes, they consider there to be a significant air leak that should be located and repaired.
Air Brake leak test:
To make sure that your air brakes are holding air and that the check valves are working properly, use the techniques found in the Commercial Drivers License Handbook for most states.
