2007-2008 Mercedes S550, S600, S63 and S65
4-Piston, 14” Two-Piece Rotor AP Racing Rear Brake Kit
Part # AP6650 and AP6650R

Brake Pros' 4-Piston, two-piece rotor AP Racing rear brake system is the ultimate rear brake upgrade for the Mercedes S-Class. When combined with the available 6-Piston, two-piece rotor AP Racing front brake system, the full potential of the S-Class can be realized at any speed. This is especially true when running oversized wheels that can overwork the factory brakes.

AP Racing is the same manufacturer proven through years of success with the McLaren-Mercedes F1 team for its legendary quality and performance. Packing a massive increase in stopping power, this kit gives the performance-minded driver full confidence whether running the big Merc through its paces around town or out on the open road. As with all AP Racing kits, it is designed to perform with the factory OE master cylinder and is fully compatible with factory ABS subsystems. The world famous AP Racing 4-Piston aluminum calipers with 14" (356mm) cross-drilled and slotted two-piece rotors ensure that your S-Class will stop time and time again, reducing the fade found in the stock brakes. All Brake Pros kits are shipped 100% complete with caliper mounting brackets, DOT-compliant stainless steel brake lines, Mintex Xtreme brake pads and all the necessary high-grade installation hardware.

Mintex Xtreme Motorsport pads provide superior stopping capability without the usual wear and noise compromises. These pads perform between 0-1300º F with less noise than most "high performance" pads. They also work cold, unlike other compromised pads which may leave you shaken up on the first stops of the day.

Now you can possess the same advanced brake technology preferred in Formula 1, NASCAR, World Rally Car (WRC) and more at an affordable price. Designed for use with our 6-Piston front kit (AP6600/AP6600R) so you can perform a full system four corner upgrade.

Available in two colors: Red calipers with black script or Black calipers with yellow script. These kits are also available in a slotted only rotor configuration - simply add "S" to the part number.
