Using your StopTech Sport Axle Pack Slotted Brake Kit is easy. First, make sure your car is parked on a flat surface and the engine is off. You can directly replace your old brake pads with the ones included in the kit. Just follow the standard brake - pad replacement steps in your car's manual. For the rotors and brake lines, if you're not confident in doing it yourself, it's best to have a professional mechanic install them. When driving with this new brake kit, you'll notice improved stopping power right away. As for maintenance, regularly check the brake pads for wear. If they get too thin, it's time to replace them. Also, keep an eye on the brake lines for any signs of damage or leaks. And don't forget to check the brake fluid level periodically and top it up if needed. This will help ensure your brakes work well for a long time.
