Why are my brakes sticking?

This has been going on for a while. First i replaced the calipers, pads,and rotors. That only made it almost impossible to drive. Then I replaced the rubber hoses and bled them again. When I use the car in the morning they get me to work, but on the way home the pedal becomes stiffer and stiffer until at least the right side is totally stuck and stalling the car. There can't be much left at this point. I am becoming frustrated. I'll put a master cylinder on there, but if anyone has a different idea please let me know! I really don't wanna put any more parts that don't need replaced on there at this point. 95 ford probe gt. Part store lady said the problem is circled on the hood and I'm almost with her.
