Air brake check (Begin with air pressure at approx. 90 psi) (Automatic failure if done incorrectly)
1. With air pressure built to governor cut-out (120-140 psi) Shut off engine. Turn key back on so gauges work. Release brakes by pushing in both air valves. Hold brake pedal down for 1 minute and make sure that air pressure does not drop more than 4 psi for combination units with air brake equipped trailer (3 psi for single vehicle)
2. Pump brake pedal until pressure drops to approximately 60 psi and make sure warning light and/or buzzer come on
3. Pump brake pedal until pressure is approx 40psi. Look and listen for both valves to pop out. (Do not pull the valves out by hand)
