Brembo 2PD.9027A3 GT Series Rear Big Brake Kit 380x28mm Drilled 2-Piece Rotors 4-Piston Silver Calipers

The Brembo 2PD.9027A3 is a complete GT Series rear big brake kit featuring 380mm x 28mm 2-piece drilled rotors paired with 4-piston cast monobloc radial-mount calipers in silver. Engineered for drivers who demand maximum stopping power and fade resistance, this kit delivers a substantial upgrade over factory brake systems for both spirited street driving and track-day performance.

At the heart of the kit are Brembo's cast monobloc aluminum calipers, precision-machined for outstanding rigidity and minimal flex under heavy braking loads. The fixed, opposed-piston design ensures more uniform pad contact and wear across the full friction surface, while the reduced individual piston diameter means more precise modulation and a firmer, more consistent pedal feel.

The 2-piece floating disc design uses an aluminum alloy hat that reduces unsprung mass for improved handling and suspension dynamics. The floating mount system allows greater radial and axial movement, enabling superior heat dissipation during repeated hard stops and significantly reducing the risk of thermal cracking. The cross-drilled rotor surface further aids in venting heat, brake gases, and debris from the friction interface.

Key Features:

• 380mm x 28mm 2-piece drilled rotors with aluminum alloy hat for reduced unsprung weight
