Interesting brake problem
Installed all new calipers, rotors, wheel bearings on the 1998 Dodge one ton dually .
(quite the job) First drive out I can tell something is wrong, brake pedal is getting higher and higher (almost no travel to apply brakes) Then i notice a lot of drag, Brake(s) are hanging up. I had wire brushed , rust killed and painted all things to insane detail. All slide surfaces for calipers were better then new. So to the point - front left caliper and rotor almost on fire. Very rural road i sit there for a 1/2 hour. bang on caliper, pry ETC. Finally i open the bleeder valve and out gushes fluid like under pressure.! OK at that point i figure collapsed swollen hose(s) Here is the STRANGE part. After that event drove home Now it all works fine.....................cured .

I've had brake hoses do that before. Once the pressure is bled away, the collapsed section gets back into shape and will pass fluid freely for a while. I figured it might be associated with some heat loaded fluid affecting the collapsed section when the brakes warm up.
New hoses will fix that. Go ahead and replace the one at the center of the rear axle while you're at it.

I agree with the hose assessment, I am sure you will agree that it was akward as hell, dealing with the caliper while you were working on it. There is not enough hose to set the caliper out of the way while you are changing the rotors, and what ends up happening, is that huge caliper, that weighs as much as a small block chevy, falls off the control arm , and its weight ends up dangling off the hose, which will kink it internally.

I replaced all the brake lines on my Ram, after half of them rusted out. Twice under braking. ( not a good feeling when your pedal goes to the floor at 70mph...) They are known for that. I went with stainless lines and braided hoses.

Had that happen on my bug one time, new brake hoses at all four corners will be a nice 3 day weekend project for you

I agree on the hoses. it is just weird from the jump the one caliper never retracted . With each brake application it just got worse. Then I bled it off and it has been fine.
I find that......strange.
