Changed rear pads on my csc first of this year. Original set lasted 2 years plus 50k. Figured I wouldn't have to worry about for a while. Started making noise recently first thought was a wheel bearing. outside pads on left side are down to the metal. Ate up rotor on that side. Has anybody ever had to replace a rotor and can u get this animal from a regular parts house or do I have to get it from CSC. I thought about getting it machined down but not sure about spec on how far down I can go and does anybody know what the torque spec on caliper bolts are. I'll call CSC tomorrow but I wanted to check here first. Any information would be greatly appreciated. Tks for looking
