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

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 serious upgrade for the front axle. This kit replaces your factory front brakes with a much larger, more robust system designed for demanding use, offering a notable improvement in braking performance under various conditions.

At the heart of this kit are the Brembo 6-piston GT calipers, cast from high-strength aluminum for a solid feel and reduced weight. These calipers house larger brake pads, which increase the pad surface area contacting the rotor. This larger contact patch, combined with the substantial 380x34mm two-piece rotors, allows for much greater heat dissipation and a higher threshold before brake fade occurs. The rotors themselves are drilled, which helps to vent gases and moisture away from the pad surface, contributing to consistent braking performance, especially during repeated hard stops. The two-piece design also helps manage heat and can make rotor replacement simpler down the line.

This kit is designed as a direct fit for the specified Sienna models, meaning it bolts on without requiring extensive modifications. While this is a significant upgrade, it's important to remember that a brake system works best when all its components are in good condition. Ensure your rear brakes and brake fluid are also up to the task to achieve the full benefit of this high-performance front kit. Installation will require specific tools and knowledge of brake system procedures; refer to the manufacturer's instructions for detailed guidance.
