Brembo 21+ Sienna (XL40) Front GTR BBK 6 Piston Billet380x34 2pc Rotor Slotted Type3- Nickel Plated

This is the Brembo GTR Big Brake Kit for the front of your 2021 and newer Toyota Sienna (XL40 chassis). This kit is designed to significantly upgrade your braking performance, offering a substantial improvement over the factory setup. Brembo is well-known for its high-performance braking systems, and this GTR kit represents their leading edge for street and track use.

At the heart of this kit are the massive 380x34mm two-piece rotors. These are constructed from a high-carbon cast iron friction surface, paired with a billet aluminum hat that's nickel-plated for corrosion resistance and a clean look. The two-piece design allows for better thermal management, as the hat can expand and contract independently of the rotor ring, reducing the risk of warping. The rotors feature a Type 3 slotting pattern, which helps to sweep away dust and gas that can build up between the pad and rotor surface, ensuring consistent stopping power even under heavy use. The calipers themselves are a 6-piston billet aluminum design, offering immense clamping force and a solid pedal feel. The nickel plating on the calipers and rotor hats not only looks sharp but also provides a layer of protection against the elements.

Installing a big brake kit like this is a significant upgrade, and it's important to ensure all components are properly installed according to Brembo's instructions. This kit is designed to be a direct replacement for your factory front brake components, but it's always recommended to have a qualified technician perform the installation to ensure optimal performance and safety. You'll notice a dramatic improvement in stopping distance and fade resistance, making it ideal for heavier vehicles like the Sienna that can benefit from enhanced braking capacity.
