Brembo 09-15 GLK Rear GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Slotted Type-3-Black

The 345x28mm, two-piece rotor design in this Brembo GT Big Brake Kit is a key feature for managing heat on your GLK's rear axle. This kit is built around a robust 4-piston caliper, offering a significant upgrade over the factory setup for improved stopping power and consistency, especially during spirited driving or heavy braking situations. The cast aluminum caliper body is both strong and lightweight, helping to reduce unsprung mass which can positively affect handling.

Each rotor is a two-piece design, meaning the hat and the friction surface are separate components. This construction allows for better thermal management, as the hat can expand and contract independently of the rotor ring, reducing the risk of warping. The Type-3 slotting pattern on the rotors is specifically chosen for its ability to help clear dust and gas away from the pad surface, maintaining a more consistent grip. This slotting also helps to keep the rotor surface cleaner, which contributes to more reliable braking performance over time. The calipers themselves are finished in a durable black coating that not only looks good but also offers a layer of protection against the elements.

This kit includes everything you need to perform a comprehensive rear brake upgrade. You'll find the calipers, the two-piece rotors, brake pads, and all the necessary mounting hardware and brake lines to ensure a proper installation. While this is a significant upgrade, it's designed to be a direct fit for the specified GLK models, simplifying the installation process. Refer to the manufacturer's installation instructions for specific details and torque specifications.
