Using these Hawk High Performance Street 5.0 brake pads is straightforward. Just install them like you would with any standard brake pads for your compatible Subaru models. Make sure to follow the vehicle's service manual during installation. When it comes to using them, you'll notice an immediate improvement in braking performance. But remember, even though these pads are durable, avoid excessive hard braking all the time as it can still wear them out faster. 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 to ensure optimal performance. Since these pads are made in the USA, you can trust their quality and performance for a long - lasting driving experience.
