Brembo 1TD.9513A1 GT Series Big Brake Kit 6-Piston Monobloc Front Axle Set

The Brembo 1TD.9513A1 is a complete front axle GT Series Big Brake Kit engineered for drivers who demand maximum stopping performance on both the street and the track. Part of Brembo's renowned Gran Turismo upgrade line, this kit delivers motorsport-derived braking technology in a street-legal package.

Key Features:

• 6-Piston Cast Monobloc Calipers — Radial-mounted, machined from a single casting for exceptional rigidity and minimal deformation under extreme braking loads
• 405mm x 34mm 2-Piece Floating Discs — Oversized rotors with an aluminum alloy hat to reduce unsprung weight and manage thermal stress
• Directionally Vented Rotors — Available in cross-drilled or slotted finish to maximize heat dissipation, eliminate brake dust and gases, and continuously refresh the pad surface
• Opposed Multi-Piston Design — Smaller individual piston diameters distribute clamping force more evenly, resulting in uniform pad wear and precise pedal modulation
• Metal-Braided Stainless Steel Brake Lines — Minimizes brake fluid absorption for a firm, consistent pedal feel
• High-Performance Brake Pads Included — Optimized friction material for both street and performance driving
• CNC Billet Caliper Adapters & All Hardware Included — Ships pre-assembled for straightforward installation

The 2-piece floating disc design increases thermal capacity to dramatically reduce brake fade during repeated hard stops. The floating mount allows greater radial and axial movement, improving heat dispersion and resistance to thermal shock cracking. Calipers are available in Brembo's signature painted finishes, adding a distinctive, aggressive look through open-spoke wheels.

This complete axle kit is backed by Brembo's two-year warranty against manufacturing defects, reflecting the brand's confidence in their engineering and build quality.
