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

This is the Brembo GT Big Brake Kit for the front of your 2021 and newer Toyota Sienna XL40. If you're looking to significantly improve your Sienna's braking performance, especially under heavy loads or during spirited driving, this kit is designed to do just that. It replaces your factory front brake components with a much larger and more robust setup, featuring six-piston calipers and larger two-piece rotors.

The calipers are cast from aluminum for a good balance of strength and light weight, and they house six pistons per side. This multi-piston design allows for more even pressure distribution across the brake pad, leading to better stopping power and heat management. The rotors are a substantial 380mm in diameter and 34mm thick, providing a larger surface area for heat dissipation and increased braking leverage. They are a two-piece design, with a cast iron friction ring bolted to an aluminum hat, which helps reduce weight and manage thermal expansion. The Type-3 slotting pattern on the rotors is designed to help sweep away dust and gas buildup, maintaining consistent pad contact and performance, especially during repeated hard stops.

This kit includes everything you need to upgrade your front brakes, including the calipers, rotors, brake pads, and necessary mounting hardware. It's a comprehensive package aimed at providing a noticeable improvement in braking feel, fade resistance, and overall stopping capability for your Sienna. Proper installation is key to realizing the full benefits of this high-performance brake system.
