Brembo 09-15 7-Series Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type3-Silver

The 380x28mm, two-piece rotors in this Brembo GT Big Brake Kit are cast iron, a material chosen for its ability to handle heat and provide a solid foundation for braking performance. This kit is specifically for the rear of 2009-2015 BMW 7-Series models, giving you a significant upgrade over the factory setup. The four-piston calipers are designed to clamp down on these larger rotors, increasing the leverage and surface area for more effective stopping power.

Brembo's GT BBK is built for drivers who demand more from their braking system. The rotors feature a Type 3 slotting pattern, which helps to vent gases and dust away from the pad surface. This keeps the pads making consistent contact with the rotor, reducing fade during hard braking and improving pedal feel. The calipers themselves are a robust four-piston design, offering a strong and even pressure distribution across the brake pad for improved stopping performance and longevity.

When installing a kit like this, it's important to ensure you have the correct tools and follow the manufacturer's instructions carefully. This kit is a substantial upgrade, and proper installation is key to realizing its full potential and ensuring reliable performance. You'll want to check your vehicle's specific requirements for brake line fitment and potentially consider other supporting modifications to balance your braking system.
