Welcome Joey P. to irv2.
If your brakes got hot from heavy braking the brakes will go to the floor had a RVer last week traveling down hills and sharp curves hitting the brakes heavy, had no brakes when pulling into camp ground. Was fine when she left day of brake up, wasn't takeing out of overdrive and her speeds to high going down the hills she admits.
Told her to have checked out and maybe have fluid checked or changed.
Enjoy the forums and do post often.
