Does your home jurisdiction require air brake 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?

Pushing down on the pedal helps tighten up the brake adjustment. But to properly check adjustment, you have to go underneath and check where the slack adjuster connects to the push rod. Chock the wheels and turn off the parking brakes so you can move the slack adjuster. Wearing a pair of gloves you pull hard on each slack adjuster. If you can move it more than one inch where it connects to the push rod, then it needs adjustment. At least that is what I was told to check them.
