I just replaced my brakes and rotors(thanks to the dealership not putting the low brake squeelers on I had metal to metal in a matter of 1 day and the rotors where shot. If you see more than average brake dust on your rims check the pads.
I went with NAPA premmium rotors for $95.00 each and lifetime metallic pads $54 they have been great. Ceramics are soo hard they will eat up rotors.
