Motorhome had Drums on the rear. yup I just looked up the year that i had. 1992 Ford E350 chassis

Sunbeam had rotors. Was an option for that year and both hoses were shot in the front. That car sat a lot because it scared me to drive. Drove terrible. Tube tires. 66 sunbeam alpine. = Cool but Junk.. Once car i wasn't upset to see go

I know the Sunbeam is crazy old. So a lot of weird things happen. But the motorhome was at a year we can relate to. I find it weird that it happened to me twice and not much talk about it, but you do find it with google search with the brake hose swollen causing one caliper to be pressurized or both. And using a bleeder to release the pressure as a cure to the symptom.

EDIT> yup. teflon-lined stainless steel braided flexible brake lines. On my list of "to do's" Thanks, Leonard.
