Just got a set of replacement Brembo front rotors from BMA. I cleaned them with brake cleaner then put them on. I am using the Raybestos QS Ceramic pads that have been on the car for a couple of years now (great pads by the way). Anyway, within a day or two, I started getting a horrible noise when I did a medium to hard brake. It sounded like one or both rotors had a hard spot on them. A similar sound would be a bad front wheel bearing. Anyway, it sounded so bad I took them off and put the old ones back on. BMA suggested putting them back on and just running them for a week or two. They said some pad material needed to transfer to the rotors. Anyone have any additional info on this topic?

Grace and peace,
