Brembo 1MD.9037A2 GT-M Big Brake Kit Front 4-Piston Monobloc

The Brembo 1MD.9037A2 is a front axle Gran Turismo (GT-M) Big Brake Kit engineered for drivers who demand race-derived braking performance on the street and track. Part of Brembo's acclaimed GT Series upgrade lineup, this kit delivers a substantial step up in thermal capacity, braking torque, and pedal feel over factory brake systems.

Key Features:

• 4-Piston Cast Monobloc Caliper: Machined from a single cast aluminum billet for exceptional rigidity and minimal flex under extreme braking loads
• Radial-Mounted Fixed Caliper Design: Provides even brake force distribution across all pistons and promotes uniform pad wear
• Oversized 2-Piece Composite Disc: Floating rotor design reduces unsprung weight and dramatically increases thermal capacity to resist brake fade during repeated high-speed stops
• Slotted Rotor Finish: Continuously refreshes the pad surface, evacuates gases and debris, and maintains a stable friction coefficient for consistent bite
• High-Performance Brake Pads Included: Friction compound optimized for both street driving and track sessions
• DOT-Approved Metal-Braided Brake Hoses: Included for firm, consistent pedal feel and superior durability over OEM rubber lines
• Complete Hardware Kit: All necessary mounting adapters, brackets, and fasteners included for a complete installation
• Painted Caliper: Available in Brembo's signature colors, featuring the iconic Brembo logo for a distinctive, high-performance appearance

Brembo's GT-M kits are purpose-built to combine motorsport-derived engineering with real-world usability. The monobloc caliper architecture ensures outstanding stiffness and heat resistance, while the floating 2-piece disc's exclusive ventilation system increases resistance to thermal shock cracking by over 40% compared to conventional designs. The complete kit ships pre-assembled and includes all components needed for a full axle installation.
