I'm also guessing but I think I would want to convince myself that it's a mechanical vs. a hydraulic problem. How does the pedal feel with the engine running (so there's vacuum) and the brakes locked up? The brake fluid cap, fluid level and reservoir look normal?
Maybe next I would pull a rear wheel and open the bleeder just to see if fluid comes squirting out under pressure with no brakes applied. If all that seems normal, while I had the rim off, I'd try pulling the pads just to see if either the inner, outer or both pads is just too tight against the rotor especially after you opened the bleeder and removed any hydraulic pressure.
Or, after I hit the post button, check what Jack recommends...
