Brembo 21+ Sienna (XL40) Front GT BBK 6 Piston Cast 380x34 2pc Rotor Drilled- Fluo. Yellow

If you're looking to significantly improve the stopping power and feel of your 2021 and newer Toyota Sienna (XL40 chassis), this Brembo GT Big Brake Kit is a substantial upgrade. This kit is designed to give your minivan the braking performance you'd expect from a sports car, making it ideal for those who frequently carry heavy loads or tow, or simply want a more confident and responsive pedal feel under all conditions. The kit features a robust 6-piston caliper design paired with large 380x34mm two-piece rotors, engineered to handle much higher thermal loads than stock components.

The calipers themselves are cast from high-strength aluminum for a good balance of rigidity and light weight, finished in a striking Fluorescent Yellow. This 6-piston configuration allows for more even pad pressure distribution across the rotor surface, which translates to improved braking efficiency and reduced pad wear. The two-piece rotor design, with its 380mm diameter and 34mm thickness, offers a larger surface area for heat dissipation and increased leverage. The rotors are drilled, which helps to vent gases and water away from the pad surface, maintaining consistent braking performance even in wet conditions or during repeated hard stops. This kit is a complete front-end solution, aiming to provide a noticeable difference in braking performance and driver confidence.

This Brembo GT Big Brake Kit is a comprehensive package for those serious about upgrading their Sienna's braking system. It includes everything needed for the front axle to get you up and running with significantly enhanced stopping capability. When installing a kit of this caliber, it's always recommended to consult the manufacturer's detailed installation instructions to ensure proper fitment and function. You may also want to consider upgrading your brake fluid to a higher boiling point type to take full advantage of the kit's thermal capacity.
