Caliper hanging up heating rotor rotor expands brakes hang up more and more.
Calipers are cheap get a new pair. Scuff the old pads with some sand paper.
First look at the area on the knuckle where the brake pads slide. Look for burrs on the metal or excessive wear. If you find anything file it out smooth. Lightly grease and re assemble.
Unless you had the brake booster out it could be the adjustment on the bullet that contacts the piston in the Master Cylinder.
