Brembo 16-23 Metris (W447) Rear GTS BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type-3-Black HA

This Brembo Gran Turismo Sport (GTS) Big Brake Kit (BBK) for the rear of your 2016-2023 Mercedes-Benz Metris (W447) includes everything you need to significantly upgrade your braking performance. You'll get a pair of four-piston calipers, two-piece 345x28mm rotors with Brembo's Type-3 slotting pattern, 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 four pistons. These pistons work together to apply even pressure across the brake pad surface, leading to more consistent and powerful braking. The two-piece rotor design features a cast iron friction ring attached to an aluminum hat. This construction helps dissipate heat more effectively and reduces the risk of rotor warping under heavy use. Brembo's Type-3 slotting pattern on the rotors is a notable feature; these deep, aggressive slots help to sweep away dust and gas that can build up between the pad and rotor surface, maintaining optimal friction and preventing fade during repeated hard stops.

Installing a big brake kit like this is a significant upgrade for your Metris, especially if you frequently carry heavy loads or tow. The improved thermal capacity means your brakes will perform more reliably under sustained stress. While this kit is designed as a direct replacement for the factory rear setup, it's always a good idea to consult the manufacturer's installation guide for specific torque specifications and any other recommended procedures to ensure a proper and safe installation.
