/diy/ - Do It Yourself

What happened here? Brother borrowed my truck and I think he left the parking break on. Cable looks like it releases fine going into the hub. One rear brake is stuck on, pads just barely touching, ears on the pads are bent somehow see pic. Can’t move by hand but drives fine, coasts like its in a high gear w/o OD slowly slowing down or maintaining speed depending on the hill. Didnt have time to really look had to take it home. Just looking for thoughts before I tear into it and potentially buy all new hardware before hand to fix it in one sitting.
