Try the temperature test but check the right side very closely. Could be rather than a dragging brake but just the opposite in that the right isn't braking enough. Since the caliber pistons have to be pressed back into the housing when replacing the pads might be something to consider. Also the slide pins on right might be binding prevent the caliber from clamping effectively.
If the brake fluid was replaced try bleeding the right again. A bubble in the right caliber might cause soft braking on that side but you might feel it in the pedal.
Third, swap tires left to right or front to back. A bit of a Easter Egg Hunt but pretty easy to do.
Fourth, new pads do take a bit of time to wear in. Particularly if the disks are original and were not resurfaced.
