Using these StopTech rear brake rotors is straightforward. First, make sure your vehicle is parked on a flat, stable surface and the engine is off. Remove the old rotors carefully and then install the new StopTech rotors in their place. During installation, ensure all bolts are tightened properly. When it comes to driving, you'll notice improved braking right away. As for maintenance, it's a good idea to regularly check the rotors for any signs of wear or damage. If you live in an area with a lot of salt on the roads, rinse the rotors with clean water after driving to help prevent corrosion. And always follow your vehicle's recommended maintenance schedule. If you have any concerns or questions, consult a professional mechanic.
