These innovative brake pads are a game changer! As an automotive enthusiast I demand the best from my performance car`s brake system .Bendix's Copper-Free CFC1821 pads exceeded my expectations in terms of performance and durability. As my tests showed, the stopping power and overall braking performance were impressive. Plus, not having to worry about copper dust buildup is a huge plus for me and the environment. Overall, I highly recommend these pads..
