Brembo 09-15 GLK Rear GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Drilled-Silver

The 345x28mm, two-piece rotors in this Brembo GT Big Brake Kit are a key component, featuring a drilled surface designed to help dissipate heat and gas. This kit is specifically for the rear of your 2009-2015 Mercedes-Benz GLK, bringing Brembo's renowned performance braking technology to your SUV. The four-piston calipers are cast aluminum, offering a strong yet lightweight housing for the brake pads, which are also included and selected to work in harmony with the rotors and calipers for improved stopping power.

This isn't just a simple upgrade; it's a complete system engineered to work together. The two-piece rotor construction, with its floating hat design, helps manage thermal expansion and reduces unsprung weight compared to a single-piece rotor. The drilled pattern on the rotor surface helps to vent gases and debris away from the pad surface, maintaining consistent braking performance even under demanding conditions. The silver finish on the rotors and the cast aluminum calipers give your GLK a distinct, performance-oriented look behind the wheels.

When installing a big brake kit like this, it's important to ensure you have the correct brake lines and potentially a master cylinder upgrade to fully take advantage of the increased braking force. This kit includes everything needed to get the calipers and rotors mounted, but always refer to the manufacturer's installation guide for specific details and any additional recommendations for your vehicle. The result is a significant improvement in braking feel and fade resistance, making your GLK safer and more enjoyable to drive, especially when carrying loads or navigating challenging terrain.
