Brembo 07-13 X5 Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Drilled-Black

The 380x28mm, two-piece rotor design in this Brembo GT Big Brake Kit is a key indicator of its performance focus. This setup is built for the rear of your 2007-2013 BMW X5, aiming to significantly improve your braking performance, especially under demanding conditions. The kit centers around a robust 4-piston caliper, engineered to provide more clamping force than the factory setup, which translates directly to better stopping power and feel.

Brembo has a long history with high-performance braking, and this kit reflects that expertise. The calipers are cast for strength and durability, housing the pistons that actuate the brake pads. The two-piece rotor construction, with its 380mm diameter and 28mm thickness, offers a larger surface area for heat dissipation and a more rigid mounting platform compared to single-piece rotors. The drilled pattern on the rotors helps to vent gases and heat away from the pad surface, which can lead to more consistent braking performance, particularly during repeated hard stops. This kit is designed to be a comprehensive upgrade for your X5's rear braking system.

When installing a big brake kit like this, it's important to consider that it's a significant upgrade. While the kit is designed to fit your vehicle, professional installation is often recommended to ensure everything is set up correctly for optimal performance and safety. You'll want to ensure you have the appropriate brake fluid and potentially a brake bleeding kit on hand. This kit is a substantial investment in your vehicle's performance and safety.
