Home › CDL Practice Tests › Air Brakes Questions › Question 80
What is the correct order of the standard air brake inspection tests?
- A.Spring brake check first, then drain the tanks, then drive
- B.Build-up test, governor cut-out check, leakage tests, low-pressure warning test, and spring brake (pop-out) check
- C.Leakage test only, with no other checks needed
- D.Warning test while driving at highway speed
Correct answer
B. Build-up test, governor cut-out check, leakage tests, low-pressure warning test, and spring brake (pop-out) check
Why
The sequence follows the pressure story from full to empty: prove the system builds, holds, warns, and finally applies the springs. Doing it in order on the ground catches failures before they can matter at speed.
