If you have the bleeder screws loose and the brakes are still dragging, the problem is in the calipers. Forget everything else for now ( not a hydraulic problem )and go directly to the calipers. Pistons are not retracting ( worn square cut "O" rings or corrosion in the piston bores / pistons. Other issue could be calipers not sliding on the pins or on the sliders - again, corrosion.
