Brakes locked up?

So, for several months I was noticing I was having to put brake fluid in the master. It then started feeling like the brakes were being applied while I was driving so I looked at the wheel cylinders and didn't see the wetness I was expecting but non the less I replaced the rear wheel cylinders, turned the drums and put new brake shoes on the rear, turned the front rotors and put new pads on the front. Bled the brakes starting at the right rear, left rear, right front, left front. I go for a test drive and again it's feeling like the brakes are being applied. I Jack it up in the rear and the tires spin fine so I jack up the driver's side and it doesn't spin well, put a jackstand there and lift up the passenger side to find the same thing. I crack the bleeder screw take it all the way out and nothing comes out. So, I pump the brakes 3 times to deplete the system and crack the bolts from the master to the power brake booster and the brake booster is full of brake fluid. Figure okay found the problem replace the booster and the master, him everything back up and bleed the system and again the brakes are feeling like they are being applied. Figure it was the wrong one or defective so I took it out and went back to Napa for them to tell me it was the wrong one so I put the new one in and didn't pay attention to the bolt pattern of the master, only the side that came into the vehicle. Turns out after I get it in the master won't bolt to it because the bolt pattern is a 1/2 inch off. Take that one out and take it back for them to tell me the first one was right and might have been defective. Take the 3rd one home, install it and bleed the system and again the brakes feel like they are being applied. I am to that point of second guessing myself and I'm just being some guidance and advice thank you.
