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

The 380x34mm two-piece rotors in this Brembo GT Big Brake Kit are cast iron, a material chosen for its excellent heat dissipation and friction properties, which are crucial for consistent stopping power under demanding conditions. This kit is specifically designed for the 2021 and later 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, leading to improved pedal feel and reduced stopping distances.

Brembo's GT Big Brake Kits are well-known for their robust construction and performance enhancements. The calipers are typically made from a strong cast aluminum alloy for a good balance of strength and weight, helping to reduce unsprung mass. The rotors are slotted, a design feature that helps to vent gases and heat away from the pad surface, maintaining optimal braking performance even during repeated hard stops. This kit includes everything needed for installation, ensuring a direct fit for your Sienna.

When upgrading your braking system to this level, consider that you're investing in a setup designed for sustained performance. The larger rotor surface area and the multi-piston caliper work together to manage heat more effectively than stock components. This means less brake fade during spirited driving or when carrying heavy loads, and a more confident, responsive feel at the pedal. This kit is a solid option for Sienna owners looking to significantly improve their vehicle's stopping capability.
