Brembo 00-02 S4/02-05 A4/06-08 A4 Front GT BBK 4 Piston Cast 365x29 2pc Rotor Drilled- Yellow

This Brembo GT Big Brake Kit (BBK) for your 2000-2002 Audi S4, 2002-2005 Audi A4, or 2006-2008 Audi A4 includes everything you need to significantly upgrade your front braking system. You get a pair of Brembo's yellow 4-piston GT calipers, two 365x29mm two-piece rotors that are drilled for improved cooling, and all the necessary hardware to get them installed. This kit is designed to replace your factory front brake setup with a much more robust and capable system, offering improved stopping power and heat management for spirited driving or heavy use.

The calipers themselves are cast aluminum, which keeps them strong yet relatively lightweight. The 4-piston design means more pad surface area is in contact with the rotor, leading to more even pressure distribution and better braking force. The two-piece rotor construction is a notable feature; it allows the rotor ring to expand and contract independently of the hat, which helps reduce the risk of rotor warping under extreme heat. The drilled holes in the rotor surface help vent hot gases and moisture away from the pad surface, which is crucial for maintaining consistent braking performance, especially during repeated hard stops. This kit is a substantial upgrade for drivers who demand more from their braking system.

When installing a big brake kit like this, it's always a good idea to refer to the manufacturer's installation instructions for specific details regarding hardware torque specifications and any required modifications. While this kit is designed as a direct replacement for the factory brake components on the specified Audi models, ensuring proper fitment and function is key. You'll likely notice a significant difference in pedal feel and braking confidence after installation.
