Brembo Brake Kits dramatically increase braking performance, safety and the looks of your Mercedes. No wonder it's so much fun to drive a race car! When your Mercedes has this level of stopping control, you will have a new experience in driving and safety. These Brembo brake kits are the very same parts used in championship-winning race cars. The vented, cross-drilled rotors are fitted to billet aluminum hats, creating a "floating" disc for improved performance, pedal feel, and heat control. And most importantly, even brake wear and shorter stopping distances. Brembo's aluminum 4 or 8 piston calipers utilize sequentially sized pistons for maximum stopping power. Aircraft quality mountings and hardware include stainless steel brake lines by Goodridge. They are perfectly matched, with all the latest factory ABS and traction control systems. You cannot buy better high performance brakes! Complete kit come with instructions, rotors, hats, calipers, pads, and steel brake lines. Sold and priced per axle. Fitment for just about every late model Mercedes-Benz automobile. Special Note: Since Big Brake Kits have larger rotors and calipers, they will not work on standard 16" wheels. You must upgrade to 17" or larger diameter wheels (W220 S-Class, W215CL-Class, and W163 ML requires 18" wheels or larger to clear calipers).
