I had my passenger rear stick a little when I first bought it, only did it a few times, (Wheel was getting hot to the tough, squeaking) I assume from sitting. (PO used it little) I took the wheel off, took the pads off, cleaned the pads and rotors really well with brake cleaner, cleaned the caliper really well, greased up the pistons, then used my kit to compress it back in all the way. Cleaned it again, lubed the seal area and pad slides, and it had been good since. Mileage instantly rebounded from 17 to 20.
