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

The 345x28mm two-piece rotors in this Brembo GTS Big Brake Kit are cast iron, chosen for their ability to handle heat during hard braking. This kit is specifically for the rear of your 2016-2023 Mercedes-Benz Metris (W447) van, aiming to significantly improve your braking performance. The four-piston calipers are a substantial upgrade over stock, designed to provide more clamping force and better heat dissipation, which is crucial for maintaining consistent stopping power when you need it most.

Brembo's GTS kit includes slotted rotors, which help to sweep away dust and gas that can build up between the pad and rotor surface. This slotting pattern is their Type-1 design, and it works in conjunction with the larger, four-piston calipers to offer a more responsive pedal feel and reduced stopping distances. The calipers themselves are finished in black, adding a clean, performance-oriented look behind your wheels. Because this is a Big Brake Kit, it's designed to be a comprehensive upgrade, meaning you're getting a matched set of components engineered to work together for a noticeable improvement in braking capability.

When installing a kit like this, it's important to follow the manufacturer's instructions carefully, as it involves replacing major braking components. You'll want to ensure you have the correct tools and potentially a helper for the job. After installation and a proper bedding-in procedure, you should experience a more confident and capable braking system, especially when carrying heavier loads or driving in demanding conditions.
