I'd start with the rubber brake lines. They can break down over time and not let the fluid back into the master cylinder... just did this a month ago for my driver front.
I have been having trouble with my brakes sticking after I apply the brakes. For about 2 seconds I can feel them dragging. So far I have replaced the 2 rear cylinders, rear drum, rear pads, all the e-brake cables, front calipers, rotors and pads. and flushed new fluid thru the lines. Could the master cylinder be not releasing pressure after apply the brakes? I'm not sure how the system releases the pressure.
You have to find out if it's just one brake sticking or all of them? it was all of them for me and my mechanic told me a seal went in the master cylinder or the hydroboost and thats how it would start to apply the breaks on it's own.
As it turns out, it is the rubber brake hoses that go to the front wheels. What happens (according to my parts guy) is that the metal bracket that wraps around the hose rusts over time. As the rust builds up on the ID of the bracket it restricts the flow more and more. I pried open the brackets and sure enough the ID had a layer of rust that was pinching the hose (the hose was visibly deformed). I cleaned it up and reassembled and the problem went away. I have my brakes back!
