All the ds brake components were removed. I called dexter and got the part numbers for replacement loaded backing plates and found them for $45 each online so that solves the braking problem. As for the leaks there's no rot from where the roof vent was leaking except for the ceiling panels. I have not looked for further rot yet but I am going to pull a few more panels and check for rot before I go any further. if everything checks out then I am going to fix the leak and damaged panels and brakes and just use it through the summer and buy a new camper.
