I had an Excursion and a 2000 Econoline E350. Both had issues with the inner lining of the flex hoses sluffing off and causing a restriction in the hose that kept the calipers from fully retracting.
I experienced this in the 1980's on my 1970 Mustang. Drum brakes and one on the front was not working well, finally removed the hose from the wheel cylinder and push hard on the pedal and only a couple of drops would work their way thru.
More recently the problems I experience is the phenolic pistons on calipers gumming up and seizing up when you step on a hot brake. I have had it happen twice on my old Ford Ranger, and a co-worker had it happen twice on his '04 RAM 3500 DRW, both of his were rear calipers and not hot before they started locking up. First was one side, then later the other.
