This reads all to familiar to me. Just my op here I don't think you will find it in the brakes, my op is that it's a tranny problem IE not downshifting right, it won't match trany gear to speed of the wheels under med to hard braking, almost like a hyld lock. I had a truck here that was doing the same thing he gave up and traded it in before I could find out what was going on, like you all brakes where new twice all the way around the truck. This happens to some just before the t case busts in half.
Edit; Try the abs trick odds are it won't do a thing.
