The other day on my 96 GL 2.5 my drivers side front brake started making a awful noise. When I checked it, the top 1/2 inch of my rotor is getting ground indentations in it.(It looks like a bright silver halo that is rougher than crap) I mean they are rough ridges. I have some pad left and am not sure if it migh be something else. I know my rotor is shot because there is no way they could smooth this out. Just wondering if some one could give me a heads up befor I change it out this weekend.
Thanks
