Using this StopTech brake kit is straightforward. First, make sure your vehicle is a 2005 - 2007 Subaru STI. Remove the old brake pads, rotors, and brake lines. Then, install the new components included in the kit - the drilled rotors, sport brake pads, and stainless steel brake lines. Ensure everything is tightly fitted. When it comes to using the brakes, you'll notice an immediate improvement in pedal feel and stopping power. For maintenance, regularly check the brake pads for wear. If they are getting thin, it's time to replace them. Also, keep an eye on the brake lines for any signs of damage or leaks. Make sure to use the brakes gently during the first few drives after installation to allow the components to bed in properly. This will help you get the best performance out of your new brake kit.
