Brembo 2PD.8025A1 GT Series Rear Big Brake Kit 4-Piston Black 345x28mm 2-Piece Drilled Rotors

The Brembo 2PD.8025A1 is a GT Series rear big brake kit featuring 4-piston monobloc calipers finished in black and 345x28mm (13.6") 2-piece cross-drilled discs. Sold as a complete axle set, this kit arrives pre-assembled with all necessary hardware included for a straightforward installation.

At the core of this GT System are 4-piston monobloc aluminum calipers machined from a single billet of cast aluminum. This monoblock construction delivers outstanding rigidity and minimizes deformation under heavy braking, ensuring consistent, predictable pedal feel in both street and track environments.

The kit's 2-piece 345x28mm cross-drilled discs feature an exclusive venting system that improves cooling capacity and increases resistance to cracking caused by thermal shock by over 40%. The floating disc design reduces unsprung weight and promotes rapid heat dissipation compared to conventional one-piece rotors.
