Brembo 16-23 Metris (W447) Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type-1-Silver

This Brembo GT Big Brake Kit for the rear of your 2016-2023 Mercedes-Benz Metris (W447) includes everything you need to significantly upgrade your braking performance. You'll receive a pair of Brembo 4-piston calipers, two 345x28mm two-piece rotors with a Type-1 silver finish and slotting, and all the necessary hardware for installation. This kit is designed to replace your factory rear brake components with a more robust and capable system, offering improved stopping power and heat management.

The calipers in this kit are cast aluminum, which helps keep unsprung weight down while providing a solid foundation for the 4 pistons. These pistons work together to apply even pressure across the brake pad, leading to more consistent and powerful braking. The two-piece rotors are a standout feature; they consist of a cast iron friction ring bolted to an aluminum hat. This design helps reduce heat transfer to the hub and allows the rotor to expand and contract more freely under thermal load, which can help prevent warping. The slotting on the rotor surface is designed to help clear away brake dust and gases that can build up between the pad and rotor, ensuring a cleaner contact surface and more reliable performance, especially during repeated hard stops.

Installing a big brake kit like this is a substantial upgrade for your Metris, particularly if you frequently carry heavy loads or tow. While this kit is designed as a direct replacement for the factory rear brake system, it's always recommended to consult the manufacturer's installation guide for specific torque specifications and any required tools. The Type-1 silver finish on the rotors adds a clean, performance-oriented look behind your wheels.
