Crikey, what a tale.
Thanks for the reminder to always chock before unhitching.
And to add to this:
I frequently check the brake drum temperatures after a "hard" brake to make sure they are working. Just a touch.
That's how I discovered that one of my drums had been greased by a leaky seal.

You need to do a pull test with 7-pin disconnected and breakaway pin out again. Just hearing the brakes work or that hum/whine at each wheel with the brakes on and trailer stopped does not tell the tale.
I have a brake job coming up so I know that. I get the 12amps ok, the voltage is good, get the hum/whine. You can hear the brakes apply. But the trailer has "no brakes."
Various possibilities, all expensive, but never mind that--the point is you have to do the pull test to see if the brakes actually stop the trailer from moving, both with the breakaway test as above, and also with the brake controller and 7-pin way with no truck braking and the manual slider on the brake controller.
