I don't know..... I have a honda Pilot that had warped rotors and did the same thing when braking and all they did was turn them as well and I wanna say that was at 32k miles and it now has over 90k miles with smooth breaking. Maybe it has something to do with how long they were ridden untrue. Maybe they got pretty wet right after they got really hot so then the brake pads would not have been wearing unevenly with them.
