Brembo 21+ Sienna (XL40) Front GT BBK 6 Piston Cast 380x34 2pc Rotor Slotted Type-1-Black

The 380x34mm two-piece rotors in this Brembo GT Big Brake Kit are cast iron, a material chosen for its excellent thermal capacity and wear resistance, which is crucial for sustained stopping power. This kit is specifically designed for the 2021 and newer Toyota Sienna XL40 platform, offering a significant upgrade over the factory braking system. It features a 6-piston caliper design, which distributes braking force more evenly across the larger rotor surface. This translates to improved pedal feel and a more confident braking experience, especially under heavy loads or during spirited driving.

Brembo's GT Big Brake Kits are a comprehensive solution for those seeking enhanced performance. The calipers are constructed from cast aluminum for a strong yet lightweight housing, and the rotors are slotted. These slots help to vent gases and debris away from the pad surface, maintaining consistent friction and reducing the risk of brake fade during repeated hard stops. The two-piece rotor design also helps manage heat more effectively than a traditional single-piece rotor, as it allows for independent expansion and contraction of the rotor hat and friction ring.

Installing a big brake kit like this is a substantial modification that aims to improve the overall braking performance of your Sienna. It's a popular choice for owners who frequently tow, carry heavy loads, or simply want the best possible stopping power and feel from their vehicle. This kit includes everything needed for installation, ensuring a direct fit for the specified Sienna models.
