Using this EBC S20 pad and rotor kit is easy. First, make sure your vehicle is safely parked on a flat surface and the engine is off. Remove the old pads and rotors carefully. Then, install the new pads and rotors from the kit. Apply the included caliper lube as directed. After installation, take a short test drive at a low speed to allow the pads to break in. This will help them work at their best. When it comes to maintenance, regularly check the brakes for any signs of wear or damage. Keep the rotors clean to prevent rust. If you notice any strange noises or a decrease in braking performance, have your brakes inspected right away. Also, remember that this kit is designed for specific Mitsubishi Lancer models from 2008 - 2015, so make sure it's the right fit for your vehicle.
