My GXP is makin some nasty brake squeling noise, it is driving me crazy and I am not sure what I need to do. The stock pads were semi-metallic or something and they made insane amounts of break dust on the wheels. Before winter I bought ceramic pads from vatozone and I now notice that my breaks squeal and my rotors look like shit, not warped but they have groves. When I do a panic stop the noise will go away for about a day. Can I just turn the rotos and be ok? Do I need new rotors and pads? I would rather not put new rotors on because they are cross drilled 13" and some what expensive. So what do I need to do.
