Using these brake pads is straightforward. Just replace your old brake pads with these Hawk HPS 5.0 ones following the standard brake pad replacement procedure. When installing, make sure to clean the brake calipers and rotors properly. As for precautions, avoid sudden hard braking right after installation to allow the pads to bed - in. For maintenance, regularly check the thickness of the brake pads. If they get too thin, it's time to replace them.
