Using your EBC S2 brake kit is easy. First, make sure you fit the upgrade pads on both the front and rear or only on the front. Don't try to remove the Thermic Black coating on the rotors before installation. Just install the pads and rotors as you normally would. When you start driving, the coating will gradually wear off in the areas where the pads touch the rotors within the first 10 to 20 stops. As for maintenance, keep an eye on your brake performance. If you notice any strange noises or reduced braking power, it might be time to check the pads and rotors. Remember, don't use brake cleaner or any other method to remove the Thermic Black coating, or you'll void the EBC warranty.
