Brembo 16-23 Metris (W447) Rear GTS BBK 4 Piston Cast 345x28 2pc Rotor Drilled-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 get a pair of four-piston aluminum calipers, two-piece 345x28mm drilled rotors, high-performance brake pads, and all the necessary mounting hardware and stainless steel braided brake lines. This kit is designed to replace your factory rear brakes with a more robust system capable of handling increased demands.

The calipers are forged from aluminum for a strong yet lightweight construction, housing four pistons that apply even pressure across the brake pad surface. This results in more consistent and powerful braking. The two-piece rotor design features a cast iron friction ring bolted to an aluminum hat. This design helps dissipate heat more effectively, reducing the risk of brake fade during heavy use, and also helps to reduce unsprung weight. The drilled pattern on the rotors helps to vent gases and heat away from the pad surface, further improving stopping power and consistency, especially under demanding conditions. Brembo is a well-known name in braking systems, and this kit represents their commitment to performance and reliability.

When installing this kit, you'll want to ensure you have the correct tools and refer to the manufacturer's installation instructions for proper fitment and bleeding procedures. Because this is a significant brake upgrade, it's always a good idea to have your brake system professionally inspected after installation to confirm everything is functioning as it should. This kit is a substantial investment in your vehicle's safety and performance, offering improved stopping power and feel for your Metris.
