Brembo 10-14 E350 Sedan/12-14 CLS350 Rear GT BBK 4 Piston Cast 2pc 328x28 2pc Rotor Drilled-Black

This Brembo GT Big Brake Kit for the rear of your 2010-2014 E350 Sedan or 2012-2014 CLS350 includes everything you need to significantly upgrade your braking system. You get a pair of Brembo 4-piston aluminum calipers, two 2-piece 328x28mm rotors that are drilled for heat dissipation, and all the necessary hardware to get them installed. This kit is designed to replace your factory rear brake components with a much more robust setup, offering improved stopping power and heat management for spirited driving or heavy use.

The calipers are cast from aluminum for a good balance of strength and light weight, and they feature a 4-piston design. This means more clamping force is applied to the rotor surface compared to a typical 2-piston caliper, leading to better braking performance. The 2-piece rotor construction, with a cast iron friction ring and an aluminum hat, helps reduce unsprung weight and allows for better thermal management as the hat can expand and contract independently of the rotor ring. The drilled surface on the rotors helps to vent gases and heat away from the pad surface, which is especially beneficial during repeated hard stops.

Installing a big brake kit like this is a substantial upgrade. It's a great way to enhance the performance of your E350 or CLS350, particularly if you plan on tracking the car or frequently carry heavy loads. Make sure to consult the manufacturer's installation guide for specific details on mounting the calipers and rotors, as well as any brake fluid recommendations.
