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

Brembo is well-known for making high-performance braking components, and this GTS 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 to do just that. It replaces your factory front brakes with a much larger and more capable system, giving you more confidence during demanding driving situations or when carrying heavy loads.

At the heart of this kit are the massive 380x34mm two-piece rotors. The two-piece design helps reduce weight and allows for better heat dissipation compared to a single-piece rotor. These rotors are drilled, which helps to vent gases and moisture away from the pad surface, contributing to more consistent braking performance, especially under heavy use. The calipers themselves are a robust 6-piston cast iron design, providing more clamping force and better pad wear distribution than smaller, multi-piston calipers. This increased force and surface area work together to shorten stopping distances and reduce brake fade.

This kit includes everything you need to upgrade your front braking system. You'll find the 6-piston calipers, the 380x34mm two-piece drilled rotors, and the necessary mounting hardware to get them installed. Upgrading to a big brake kit like this is a substantial modification, so it's recommended to consult the manufacturer's installation instructions or a professional mechanic to ensure proper fitment and function. The result is a braking system that not only looks impressive behind your wheels but also offers a notable improvement in stopping performance and durability.
