Using your EBC S2 Kits with Greenstuff Pads and USR Rotors is easy. First, when installing, don't try to remove the Thermic Black coating on the rotors. Just put the pads and rotors in place as normal. Once installed, the brake pads will take care of removing the coating in the swept area within the first 10 to 20 stops. Remember, you should only fit upgrade pads to the rear if you've already upgraded the front. For maintenance, keep an eye on the wear of the pads. If you notice reduced braking performance, it might be time to check or replace the pads. Also, the Thermic Black coating helps protect the rotors from rust, so you don't need to do extra anti - rust treatments. But avoid using brake cleaner or other methods to remove the coating, as this is not covered by the EBC warranty.
