Using these brake rotors is straightforward. First, make sure your vehicle is parked on a flat and stable surface. Jack up the vehicle safely and remove the wheels. Then, take out the old brake rotors and install these new ones in their place. Ensure all bolts are tightened properly before putting the wheels back on. As for maintenance, regularly check the rotors for any signs of wear, like grooves or uneven surfaces. If you notice any unusual noises or vibrations when braking, it's a good idea to have the rotors inspected. Keep the rotors clean by using a brake cleaner during routine maintenance. And remember, always follow the manufacturer's instructions for your specific vehicle when working on the brakes.
