Using these brake pads is simple. Just replace your old brake pads with these Hawk Porsche HPS ones according to your vehicle's standard brake - pad replacement process. When you first install them, it's a good idea to go through a short break - in period. Drive normally for a few miles, and avoid hard braking during this time. As for maintenance, check the brake pads regularly for wear. If you notice any unusual noises, vibrations, or a decrease in braking performance, it might be time to have them inspected. Also, keep the brake area clean to prevent debris from affecting the performance of the pads. These pads are designed to be durable, but proper care will ensure they last as long as possible.
