Using this EBC S20 brake kit is easy. First, make sure your vehicle is parked on a flat surface and the engine is off. Remove the old pads and rotors carefully. Then, install the new Ultimax pads and RK rotors included in the kit following the standard installation procedures. Apply the caliper lube as directed. When you first start using the brakes after installation, take it easy for the first few miles to allow the pads to break in properly. For maintenance, regularly check the brakes for wear and tear. If you notice any unusual noises or reduced braking performance, have the brakes inspected immediately. Keep the rotors clean to prevent rust and ensure smooth braking. With proper use and maintenance, this brake kit will provide reliable stopping power for your Subaru.
