Using these brake pads is straightforward. First, make sure your vehicle is safely parked and the engine is off. Follow the standard procedure to remove the old brake pads and install the new Hawk DTC - 70 pads. It's a good idea to have basic mechanical knowledge or consult a professional if you're unsure. When driving with the new pads, give them a short break - in period. Start with gentle braking at low speeds to let the pads properly seat. As for maintenance, regularly check the brake pads for wear. If you notice any unusual noises, vibrations, or a decrease in braking performance, it might be time to inspect them. Keep the braking system clean to prevent debris from affecting the pads' performance. Also, always use the correct tools for any brake - related work to avoid damage.
