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

This Brembo GT Big Brake Kit starts with a 328x28mm two-piece rotor, designed to handle the heat generated during spirited driving. The kit is built around a robust 4-piston caliper, offering a significant upgrade over stock systems for improved braking performance. It's a comprehensive package aimed at drivers who demand more from their vehicle's stopping power.

The two-piece rotor construction is notable because it allows the rotor ring to expand and contract independently of the hat, which helps reduce the risk of rotor warping under extreme temperatures. The caliper itself is a fixed-mount design with four pistons, providing more clamping force and a more consistent pedal feel compared to typical floating calipers. This setup is engineered to work together to dissipate heat effectively, reducing brake fade during repeated hard stops. The drilled rotor faces help to vent gases and moisture away from the pad surface, further contributing to consistent braking performance.

When installing a big brake kit like this, it's important to ensure you have adequate clearance for the larger caliper and rotor assembly within your wheels. This kit is a substantial upgrade, and while it's designed to fit specific models, professional installation is often recommended to ensure all components are correctly fitted and bled. The result is a more responsive and powerful braking system that can handle demanding driving conditions.
