Brembo 14-18 1500 Sierra (Excl Alum Fr Knuckles) Rr GT BBK 4Pis Cast 2pc 380x32 2pc Rtr Drill-Red

This Brembo Rear GT Big Brake Kit includes everything you need to significantly upgrade your 2014-2018 Sierra 1500's rear braking performance, excluding models with aluminum front knuckles. You'll receive a pair of 4-piston cast iron calipers, two 2-piece 380x32mm rotors that are pre-drilled, and all the necessary hardware for installation. This kit is designed to provide a substantial improvement over your factory braking system.

The heart of this kit is Brembo's renowned GT caliper, featuring a robust 4-piston design. This setup allows for more even pad wear and increased clamping force compared to smaller, single-piston calipers. The large 380x32mm two-piece rotors are constructed from high-carbon cast iron, offering excellent thermal capacity to resist fade during heavy braking. The drilled surface on the rotors helps to dissipate heat and gas, maintaining consistent stopping power. The two-piece design allows the rotor and hat to expand and contract independently, reducing the risk of rotor warping.

Installing a big brake kit like this is a significant upgrade for any truck that sees demanding use, whether it's towing, hauling, or spirited driving. While this kit is designed as a direct fit for the specified Sierra 1500 models, it's always recommended to refer to the manufacturer's installation instructions for detailed procedures and any specific tool requirements. You'll notice a more responsive pedal feel and improved confidence when braking, especially under load or at higher speeds.
