Sounds like Master Cylinder., May need to replace the soft lines to calipers too as they may be breaking up inside and clogging the master up. I have experienced the master cylinder locking up front brakes personally, and if not happened to me I may not believed it was possible but is possible, Mine would release when bleed then after hitting brake pedal the front pads would not release, after hitting the brake pedal a few more times or just driving until pads were so hot they would stick to disc and lock up, put on new master never did it again.

Otherwise it may not be brakes at all and there is another issue.

Pull the front drive shaft and see if its your transfer case or front axle.
