This is the hose mounted on the solid rear axle and the only real flex is the very slight movement of the caliper? Do I have that right? If so there should be virtually no mechanical stress on the brake line. Either the line is defective or an incredibly odd road hazard. Any pictures?
I would be getting my next hose direct at a Ford dealer.
So I found the exhaust line had broken at the muffler. My theory is hot exhaust overheated the brake fluid,made the hose fail. I just replaced the entire exhaust line and muffler, will need to take trailer out to test it. I think the exhaust got really hot going up the mountain pass pulling the trailer, then hose failed on downward side.
