Brembo 09-15 CTS-V Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type-1-Silver

If you're looking to significantly upgrade the braking performance on your 2009-2015 Cadillac CTS-V, this Brembo GT Big Brake Kit is a serious consideration. This kit is designed to handle the demands of spirited driving and track use, offering a substantial improvement over the factory setup. It centers around a pair of robust 4-piston calipers and large 380x28mm two-piece rotors, engineered to provide consistent stopping power when you need it most.

The calipers themselves are cast aluminum, which helps keep unsprung weight down while maintaining the strength needed for repeated hard braking. They feature a 4-piston design, meaning more pad surface area contacts the rotor, distributing clamping force evenly for better control and heat dissipation. The rotors are a two-piece design, with a cast iron friction surface bolted to an aluminum hat. This construction helps reduce weight and allows for better thermal management, as the hat can expand and contract independently of the rotor ring. These rotors are also slotted, which helps to sweep away dust and gas that can build up between the pad and rotor surface, maintaining optimal friction and preventing glazing.

This kit includes everything you need to get these powerful brakes installed, including the calipers, rotors, mounting brackets, and high-performance brake pads. While this is a significant upgrade, it's designed to be a direct fit for the specified CTS-V models, simplifying the installation process. For the best results and to ensure proper function, it's always recommended to follow the manufacturer's installation instructions carefully and consider flushing your brake fluid with a high-temperature DOT 4 fluid.
