Brembo 04-08 S4 (B6/B7) Front GT BBK 6 Piston Cast 365x34 2pc Rotor Slotted Type-1-Black

If you're looking to significantly improve the stopping power and heat management on your 2004-2008 Audi S4 (B6/B7), this Brembo GT Big Brake Kit is a serious consideration. This kit replaces your factory front braking components with a much larger and more robust system designed for demanding use. The larger rotors and multi-piston calipers work together to provide more consistent braking performance, especially under heavy load or repeated stops.

At the heart of this kit are the 365x34mm two-piece rotors. The two-piece design helps manage heat more effectively by allowing the rotor and hat to expand independently, reducing the risk of warping. These rotors are slotted, which helps to clear out brake dust and gases that can build up between the pad and rotor surface, ensuring a cleaner contact patch and more reliable stopping power. The calipers themselves are a six-piston cast iron design, offering a larger surface area for the brake pads and more even pressure distribution compared to a typical two-piston caliper. This increased surface area and even pressure contribute to improved braking feel and reduced pad wear.

This kit is designed as a direct replacement for the front of your S4, meaning it should fit right without requiring extensive modifications, though professional installation is recommended given the complexity of a big brake kit. The cast iron construction of the calipers is well-built for durability and heat dissipation. When installing, ensure you follow the manufacturer's instructions carefully, especially regarding brake fluid type and bleeding procedures, to get the most out of this high-performance braking system.
