I did a front brake job on my wife's Prius a little while ago. Since I did it, the front left brake has been dragging, while the right side is perfect. I disassembled the left side and went over everything again. All the hardware is new, the caliper slides very easily in the bracket, and the piston moves very easy. It still drags, albeit after putting a few hundred miles on the car it's better than before, but the left side is still noticeably hotter than the right after a drive.

Anyone have any advice or tips?
