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

This Brembo GT Big Brake Kit for your 2021 and newer Toyota Sienna (XL40 chassis) includes everything you need to significantly upgrade your front braking system. You get a pair of massive 380x34mm two-piece rotors, which are drilled for heat dissipation, along with a set of Brembo's yellow 6-piston forged aluminum calipers. This kit is designed to be a direct fit for your Sienna, replacing your factory components with a much more robust setup.

The heart of this kit is the 6-piston caliper, which offers a larger piston area than stock. This means more clamping force can be applied to the rotors, leading to improved stopping power and better pedal feel, especially during repeated hard braking. The two-piece rotor design is also notable; the cast iron friction ring is mounted to an aluminum hat. This construction helps reduce weight and allows the rotor to expand and contract more freely with heat, which can help prevent warping. The drilled surface on these rotors helps to vent gases and heat away from the pad surface, maintaining consistent performance when you need it most.

Installing a big brake kit like this is a substantial upgrade for a vehicle like the Sienna, especially if you frequently carry heavy loads or tow. While this kit is designed as a direct bolt-on replacement for the factory components, it's always a good idea to consult the manufacturer's installation instructions for specific details. You'll likely notice a significant difference in braking performance and feel after installation, giving you more confidence behind the wheel.
