Brembo 1T3.9037A5 GT Series Big Brake Kit Front 6-Piston Yellow Caliper

The Brembo 1T3.9037A5 is a front axle GT Series Big Brake Kit featuring a high-performance 6-piston monobloc aluminum caliper finished in Brembo's signature yellow. Engineered from motorsport-derived technology, this complete braking upgrade delivers dramatically improved stopping power, thermal capacity, and pedal feel compared to OEM brake systems.

Brembo GT Series kits are built around a fixed, radially-mounted monobloc caliper — machined from a single piece of cast aluminum in Brembo's own foundry — providing exceptional rigidity and minimal flex under hard braking loads. The kit pairs this caliper with a large-diameter 2-piece slotted Type-3 rotor designed for maximum heat dissipation and consistent performance in both street and track environments.

Key Features:

• 6-Piston Monobloc Caliper: Fixed, radially-mounted aluminum construction for maximum stiffness and precise brake modulation
• Yellow Caliper Finish: Bold Brembo yellow powder coat with embossed logo for a race-inspired appearance
• 2-Piece Slotted Type-3 Rotor: Lightweight composite rotor design increases thermal capacity and reduces brake fade
• High-Performance Brake Pads Included: Aggressive compound pads engineered to outlast OEM units while delivering superior bite
• Motorsport-Derived Technology: GT Series components share DNA with Brembo's Formula 1 and endurance racing programs
• Complete Kit: Includes CNC-machined caliper brackets and all necessary hardware for installation
• Brembo Check Compatible: Includes QR-coded authenticity label verifiable via the Brembo Check app

The Brembo GT Series Big Brake Kit is the ideal upgrade for performance enthusiasts seeking measurable improvements in braking distance, fade resistance, and overall brake feel — whether on the street, autocross, or road course.
