That usually happens when cheap brake pads are used. Nothing can really be done about it, and it won't necessarily hurt anything. All you can do is run this set out and replace with a better quality set of brakes and rotors next time.I have asked about this on the facebook page with good advice however, i am hoping someone as experienced this. I replaced my original brakes and rotors. I used duralast gold rotors and their ceramic pads. I followed instructions and have changed them before on other vehicles with no problem. I also did remove the sliding pin bushings as they were swelled and sticking. Now I have "record grooving" on both rotors. I still have to take it apart but snow is falling so I haven't had a chance.
