Does your home jurisdiction require air brake endorsement?
Are there jurisdictions about the continent that allow people to drive air brake equipped vehicles without any type of training or license endorsement?

All of this "sitting in the cab pumping the brake pedal X number of times" is good. How do you know they really adjusted??
You measure the stroke, just like always. All of this pumping stuff isn't really necessary if you measure the pushrod stroke and it's within spec.
No one has answered my question, does the pedal go lower (as in hydralic brakes) as the adjustment gets out of tolerance? Or does the pedal go to the floor upon a stop when it is out of tolerance? Since we have professionals responding to the post, I would think they would know the answer? I normaly press my brake pedal as far as it will go, every day as I drive the MH. Usually make at least 10 stops or more each day. Do I need to do a "panic stop"? Please explain what a CDL teaches you over a "peon" like me?
Give me some info?
No, the pedal travel does not change with brake adjustment. And automatic slack adjusters are supposed to adjust automatically, without making panic stops. That's just a way of making sure they do.
Air brakes are not rocket surgery. In fact, everything that most professional truck drivers know about them can be found in the DMV commercial driver handbook, which can be picked up for free at any DMV office (in California, at least).
So if I make 10 normal stops in a day of driving, I have satisfied the CDL requirement for adjusting the brakes? I cannot imagine traveling 300 miles in a day without making at least 10 full stops. Am I being unreasonable or what?
The requirement is that you check them and maintain them within spec. You should never need to adjust them with normal use.
