Brembo 21+ Sienna (XL40) Front GTS BBK 6 Piston Cast 380x34 2pc Rotor Slotted Type-1-Black HA

This Brembo Gran Turismo System (GTS) big brake kit is designed for the front of your 2021 and newer Toyota Sienna (XL40 chassis). You'll receive a complete front brake upgrade, including a pair of 6-piston cast aluminum calipers finished in black with HA (High-Performance Aluminum) treatment, two 380x34mm two-piece slotted rotors, and all the necessary hardware to get them installed. This kit is built to handle the demands of a larger, heavier vehicle like the Sienna, offering a significant improvement in stopping power and heat management over the factory setup.

The calipers themselves are a substantial 6-piston design, which means more pad surface area contacting the rotor. This larger contact patch helps distribute braking force more evenly and efficiently, leading to better control and reduced pedal effort, especially during repeated hard stops. The rotors are a two-piece design, with a 380mm diameter and 34mm thickness, featuring slots that help vent gases and heat away from the braking surface. This is crucial for preventing brake fade and maintaining consistent performance, whether you're navigating mountain roads or just carrying a full load of passengers and cargo. The black HA finish on the calipers isn't just for looks; it's a treatment that helps manage heat and corrosion.

Installing a big brake kit like this is a noticeable upgrade for a vehicle like the Sienna, which often carries a lot of weight. You'll feel a more confident and responsive pedal, with shorter stopping distances. Because this is a comprehensive kit, it's designed to be a direct fit for the specified Sienna models, simplifying the installation process. Refer to the manufacturer's installation instructions for specific details on mounting and any required tools.
