Brembo 1MD.8045AS GT-S Series Big Brake Kit Slotted Rotors - 4-Piston 2-Piece

The Brembo 1MD.8045AS is a GT-S Series Big Brake Kit featuring 4-piston calipers and slotted 2-piece rotors, engineered for high-performance street and track driving. Born from decades of motorsport development — including Formula 1 and endurance racing — the GT-S Series represents Brembo's premium bridge between road and race applications.

Key Features:

• GT-S Series 4-Piston Calipers: Race-inspired aluminum calipers featuring ventilated pistons, recessed dust seals, and hard anodized finish for exceptional thermal and mechanical durability
• Slotted 2-Piece Floating Rotors: Lightweight composite disc design with an aluminum bell reduces unsprung weight while the exclusive venting system increases cooling capacity and improves resistance to thermal shock cracking by over 40%
• Slots dissipate heat and gas: Precision-machined slots in the braking surface help evacuate heat, brake dust, and gases for consistent bite and fade resistance
• High-Performance Brake Pads Included: Application-specific friction material pads included, optimized for both street and track performance
• Stainless Steel Braided Brake Lines: Metal-braided hoses reduce fluid expansion for a firmer, more responsive pedal feel
• CNC Billet Caliper Adapters & Hardware: All necessary mounting hardware and Brembo-engineered adapters included for a straightforward installation
• Compatible with OEM ABS & Traction Control: Fully integrates with factory hydraulic systems without modification

The GT-S caliper body is hard anodized for longevity and corrosion resistance at high temperatures, with the Brembo logo engraved in the racing-style red finish seen across the company's competition product line. Opposed pistons ensure even clamping force distribution and uniform pad wear, while the oversized rotor diameter delivers significantly more braking torque than stock.

This complete kit includes calipers, 2-piece slotted rotors, high-performance brake pads, stainless steel braided brake lines, caliper adapters, and all installation hardware — everything needed for a full brake system upgrade.
