Using this EBC S14 brake kit is easy. First, make sure your vehicle is parked on a flat surface and the engine is off. Remove the old brake pads and rotors carefully. Then, install the new EBC Greenstuff pads and RK rotors according to your vehicle's manual. After installation, pump the brake pedal a few times to ensure proper brake function. As for maintenance, check the brake pads regularly for wear. If they look thin, it's time to replace them. Also, keep an eye on the rotors for any signs of rust or damage. To prevent rust, you can clean the rotors occasionally with a mild soap and water solution. Remember, always follow your vehicle's manufacturer guidelines for brake maintenance and replacement.
