Correct answer: All of these are correct.

Answer options

  1. ATest how quickly the system loses air
  2. BCheck the pressures at which the governor cuts the compressor in and out
  3. CAll of these are correct Correct

Why

The final air brake check is a series of tests, including the governor's cut-in and cut-out pressures, the air leakage rate, the low-pressure warning, automatic spring brake application, and the parking and service brakes. A vehicle that fails any of them should not be driven until it is repaired.
