Once and for all, no matter what kind of rotor, what kind of coating or what kind of pad, where the pad contacts the rotor will be shiny uncoated bare metal. If not, you've got a problem and reduced braking because the only way brakes work efficiently is when the pad is grabbing uncoated metal. You don't need a second opinion on this.
Well in my ( second ) opinion, you are wrong...Hard ceramic brake pads do not make rotors SHINY.
if you have seen posts from people with ceramic pads, many of them complain about discolored rotors.. the reason is hard pads do not stop as well and require more pressure, which increases rotor temperature..Harder pads indeed dust less but at the expense of the rotor... the dark blue discoloration seen by many ceramic brake pad owners proves that they do NOT make the fire path shiny..
For about the tenth time in a few threads, here is a rotor that had the misfortune of having ceramic pads discolor the rotor. Does this look shiny?????
Is that the HAWK pads on the rotors in your pictures? Are your rotors zinc coated? I have a set of GM pads with about 12K on them I'm thinking of using to brake-in the rotors..
Yes, Hawk pads on my rotors in the pic...
Got new rotors in the summer, used them with the 3 yr old Hawk pads.. Now I am ready for new stock GM pads..
