Brembo 11-16 528i Rear GTS BBK 4 Piston Cast 345x28 2pc Rotor Slotted TY3L - Black HA

Brembo is well-known for making high-performance braking components, and this Rear GTS Big Brake Kit (BBK) continues that tradition. If you're looking to significantly upgrade the stopping power and feel of your 2011-2016 BMW 528i, this kit is designed to do just that. It replaces your factory rear brakes with a more robust system that can handle more heat and provide more consistent braking performance, especially during spirited driving or repeated hard stops.

This kit features a 4-piston caliper, which offers more clamping force than a typical 1-piston or 2-piston factory caliper. The calipers are cast iron, a strong material that holds up well under the stress of braking. They are paired with 345x28mm two-piece rotors. The two-piece design helps manage heat and can reduce unsprung weight compared to a solid one-piece rotor. These rotors are slotted, meaning they have grooves machined into the surface. The slots help to vent gases and dust away from the pad surface, which keeps the pads in better contact with the rotor and improves braking consistency, especially in wet conditions or during heavy use. The black HA finish on the calipers adds a clean, performance-oriented look to your vehicle.

When installing a big brake kit like this, it's important to ensure you have adequate clearance for the larger calipers and rotors within your wheels. This kit is designed as a direct replacement for the rear of your 528i, but it's always a good idea to confirm wheel fitment. You'll also want to consider flushing and replacing your brake fluid with a high-performance fluid to take full advantage of the new braking system's capabilities.
