I have a commercial Class A license and, to the best of my knowledge, there is no such thing as an air brake endorsement. There is only an air brake restriction if you are not allowed to operate a vehicle with air brakes (most likely because you took the driving test in a vehicle that did not have air brakes).
It's true that many people driving RVs with air brakes have no idea how the system works beyond the fact that it stops when they step on the brake pedal. But how many people driving RVs with hydraulic brakes have any idea how their brake systems work? Why is there no outrage over that?
Main difference between hydraulic and air brakes is that hydraulic pressure is used to apply the brakes, whereas in air systems, air is used to keep the brakes from applying. You lose hydraulics...NO BRAKES. Lose Air...Brakes apply. Much safer.
