Brembo 09-15 7-Series Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Drilled-Black

This Brembo GT Big Brake Kit (BBK) for the rear of your 2009-2015 7-Series includes everything you need to significantly upgrade your braking system. You'll get a pair of Brembo's cast 4-piston calipers, two 380x28mm two-piece rotors that are drilled for improved cooling, 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, giving you better stopping power and heat management.

Brembo is well-known for their high-performance braking components, and this GT BBK is a prime example. The 4-piston calipers offer increased clamping force over stock, which translates to shorter stopping distances. The two-piece rotors are a smart design choice; the cast iron friction ring handles the heat of braking, while the aluminum hat reduces unsprung weight and helps dissipate heat more effectively. The drilled pattern on the rotors helps to vent gases and heat away from the pad surface, which is especially beneficial during repeated hard stops. This kit is a substantial upgrade for drivers who demand more from their vehicle's braking performance.

When installing a big brake kit like this, it's always a good idea to consult the manufacturer's installation guide for specific torque values and procedures. While this kit is designed as a direct replacement for the factory rear brakes, ensuring proper installation is key to realizing its full performance potential. You'll notice a significant difference in pedal feel and braking consistency, especially under demanding conditions.
