Brembo 21+ Sienna (XL40) Front GT BBK 6 Piston Cast 380x34 2pc Rotor Slotted Type-3-Red

Brembo is well-known for making high-performance braking components, and this GT Big Brake Kit (BBK) for the 2021 and newer Sienna (XL40 chassis) is a prime example of their expertise. If you're looking to significantly improve your Sienna's stopping power and heat management, this kit is designed for that purpose. It replaces your factory front brakes with a much larger and more capable setup, featuring six-piston calipers and substantial two-piece rotors.

This kit includes Brembo's cast aluminum six-piston calipers, which are built to handle the demands of repeated hard braking without fading. Paired with these calipers are 380x34mm two-piece rotors. The rotors are slotted with Brembo's Type-3 pattern, which helps to dissipate heat and gasses effectively, keeping the pads in contact with a clean rotor surface for consistent performance. The two-piece design also helps reduce unsprung weight and allows for better thermal management compared to a single-piece rotor. This entire setup is engineered to offer a noticeable improvement in braking feel and fade resistance, especially under heavy loads or during spirited driving.

When installing a big brake kit like this, it's important to remember that it's a significant upgrade over the stock system. You'll want to ensure you have the necessary tools and potentially consult the manufacturer's installation guide for specific torque values and procedures. This kit is designed to be a direct replacement for the front braking system on the specified Sienna models, providing a substantial upgrade in both performance and aesthetics.
