Disc Brake info!

We'll I went to oreillys because the did turn rotors there and the minimum thickness is .94 and he said mine were at .96 and that by the time they got turned there would be a good chance that rotors would probably be pass the limit. He said they looked fine though, that he would just take some sandpaper to them and use them for a bit longer.

So I took some 150 grit garnet paper and began sanding! One rotor didn't really sand much dust but it got a shiney look to it. The other was sanding off a lot of like black dust and just looked dull afterwords, don't know why this is! Took a picture!
