The coating applied to the friction surface of the rotor is temporary, and as such is removed on the first application of the brakes. This means the break-in process is the same as for uncoated parts. While the procedure to bed-in the rotors may vary depending on the rotor manufacturer it is common practice to carry out five gradual stops from about 35 miles per hour, followed by four or five more aggressive stops from 45 miles per hour. By following this procedure any dirt or debris will be removed from the rotors and pads, while keeping the temperature low through light braking will normalize the rotor and remove any high-spots.
