Brembo 19+ A6 (C8)/19+ A7 (C8) Front GT BBK 6 Piston Cast 405x34 2pc Rotor Slotted Type-3-Black

The 405x34mm, two-piece rotors in this Brembo GT Big Brake Kit are cast iron with a black finish, featuring Brembo's Type-3 slotting pattern. This specific design choice is crucial for performance braking systems, as the slots help to vent gases and debris away from the pad surface. This keeps the braking surface cleaner and cooler, which translates to more consistent stopping power, especially during demanding driving conditions or repeated hard braking. This kit is built around a robust 6-piston caliper, designed to provide significantly more clamping force than the factory setup.

This kit is engineered for the front axle of 2019 and newer Audi A6 (C8) and A7 (C8) models. The 6-piston calipers, paired with the large 405x34mm rotors, offer a substantial upgrade over stock components. The two-piece rotor construction is notable because it allows the rotor ring to expand and contract independently of the hat, which helps to reduce the risk of thermal stress and warping over time. The cast iron material is chosen for its excellent thermal properties and durability under high heat loads. The calipers themselves are typically made from a strong, lightweight aluminum alloy, reducing unsprung weight while maintaining rigidity.

When installing a big brake kit like this, it's important to ensure you have adequate clearance within your wheels for the larger calipers and rotors. The kit includes everything needed for the front axle upgrade, including the calipers, rotors, mounting brackets, and high-performance brake pads specifically matched to this system. For optimal performance and longevity, it is recommended to follow the manufacturer's specific break-in procedure for the pads and rotors after installation. This ensures the pad material properly beds into the rotor surface, maximizing braking effectiveness and minimizing noise.
