Using these Hawk Porsche Front HP+ brake pads is straightforward. Just replace your old brake pads with these new ones following your vehicle's standard brake pad replacement process. Here are some things to keep in mind: When you first start using the new brake pads, give them a short break - in period. Don't suddenly apply extreme braking force right away. This helps the pads settle in properly. For maintenance, regularly check the brake pads' thickness. If they get too thin, it's time to replace them. Also, keep the braking system clean. Avoid getting dirt or debris on the pads as it can affect their performance. With proper use and maintenance, these brake pads will serve you well and keep your vehicle's braking in top - notch condition.
