Hey all,

After seeing so many raves about R1 Concepts rotors for our cars, I bought a set of 4 of their E-Line series with pads from ebay. I put the rears on yesterday, and took it for a test drive just a few minutes ago.

Well, they have a sort of metal on metal grinding noise when driving, and then the pads make noise when the brakes are applied. I'm 95% sure I didn't mess anything up when putting them on, I've done brakes on GP's at least a dozen times. Another thing, is that the pads are dusting all over the ****in place on the rotor. I'd say half of the pad surface on the rotor has brake dust on it. Anybody have any suggestions?

Do I have to break them in a certain way? I was trying to break them in on the test drive doing gradual stops from different speeds, do I have to just let them settle in some? Thanks all!
