Brembo 2PD.8056AS GT-S Rear Big Brake Kit 4-Piston 345x28mm Slotted 2-Piece Rotors

The Brembo 2PD.8056AS is a GT-S Series rear big brake kit featuring 4-piston fixed calipers and 345x28mm two-piece slotted rotors, engineered for high-performance street and track driving. Derived directly from Brembo's decades of motorsport experience, the GT-S platform delivers measurably improved stopping power, pedal feel, and fade resistance over OEM brake setups.

Key Features:

• 4-Piston Fixed Aluminum Calipers — Hard anodized for long-term corrosion resistance and thermal stability at high temperatures
• 345x28mm Two-Piece Slotted Rotors — Lightweight floating disc design reduces unsprung weight and dissipates heat rapidly; slotted finish continuously cleans pad surface and expels gases for consistent bite
• Proprietary Floating D-Bobbin Mounting — Allows both radial and axial float to minimize thermal stress and reduce noise
• High-Performance Brake Pads — Application-specific friction material compound included for immediate street and track readiness
• Stainless Steel Braided Brake Lines — TÜV/DOT homologated for safe, firm pedal response by minimizing hose expansion under pressure
• CNC Billet Caliper Mounting Adapters — Precision-machined brackets ensure proper alignment and rigid caliper placement
• Fully ABS and Traction Control Compatible — Seamless integration with factory electronic braking systems
• Complete Hardware Included — Anti-rattle clips, fasteners, and all installation hardware included for a straightforward installation

The Brembo GT-S system sits at the top of Brembo's street-performance brake line, incorporating M-Series caliper technology derived from endurance racing programs. The opposing multi-piston design clamps the rotor uniformly on both faces simultaneously, improving friction surface wear consistency and reducing the pedal travel required for maximum braking force. The two-piece rotor construction pairs a cast iron friction ring with an aluminum hat, cutting rotational inertia while maintaining the thermal mass needed for repeated hard stops.
