Using these Hawk 13 Ford Focus HPS Front Street Brake Pads is straightforward. Just replace your old brake pads with these new ones following your vehicle's standard brake pad replacement procedure. As you start using them, give them a short break - in period. Don't suddenly push for extreme braking right away. When it comes to maintenance, regularly check the brake pads' thickness. If they seem too thin, it's time to replace them. Also, keep an eye on the brake fluid level as it can affect the overall braking performance. And remember, if you notice any strange noises or a change in the pedal feel, it's a good idea to have your brakes inspected by a professional.
