Using this EBC S20 brake kit is simple. First, make sure your vehicle is safely parked on a flat surface and the engine is off. You can then remove the old brake pads and rotors following your vehicle's standard brake replacement procedure. Install the new Ultimax pads and RK rotors. Apply the caliper lube as directed for smooth operation. After installation, take a short test drive in a safe area to let the brakes break in. For best results, avoid heavy braking during the first few miles. As for maintenance, regularly check the brake pads for wear. If they look thin or show signs of damage, it's time to replace them. Keep an eye on the rotors too. If you notice any unusual noises or vibrations while braking, have your brakes inspected. Also, store the unused parts in a dry place to prevent rust.
