Brembo 1N3.9086A3 GT Series Big Brake Kit Front 6-Piston Monobloc Silver Caliper

The Brembo 1N3.9086A3 GT Series Big Brake Kit is a complete front braking upgrade engineered for drivers who demand race-derived stopping power on the street or track. Part of Brembo's renowned Gran Turismo (GT) line, this kit delivers a significant performance advantage over OEM brake systems through larger-diameter rotors, multi-piston fixed calipers, and motorsport-derived technology.

This kit features a silver hard-anodized 6-piston monobloc caliper machined from a single billet of cast aluminum for outstanding rigidity and minimized deformation under heavy braking loads. The opposed-piston design ensures even pad pressure distribution across the full rotor surface for consistent, fade-resistant performance.

Key Features:

• 6-Piston Monobloc Aluminum Caliper — Silver hard-anodized finish with Brembo logo; machined from a single billet for maximum stiffness
• 2-Piece Composite Rotor — Lightweight aluminum hat paired with a cast-iron friction ring; increases thermal capacity and reduces unsprung weight
• Type-3 Slotted Rotor Finish — Slots continuously clean and refresh the pad surface, dissipating heat, dust, and gases for consistent bite
• Directionally Vented Rotor Design — Enhanced internal venting improves cooling and increases resistance to thermal cracking
• High-Performance Brake Pads Included — Friction material optimized for both street and demanding track-day use
• Stainless Steel Braided Brake Lines — TÜV/DOT-rated lines replace soft OEM rubber hoses for a firmer, more consistent pedal feel
• CNC Billet Caliper Adapters & Hardware — Brembo-engineered mounting hardware included for straightforward installation
• OEM System Compatible — Designed to work seamlessly with the factory master cylinder, ABS, and traction control systems

The Brembo GT Big Brake Kit is supplied as a complete axle set, pre-assembled and ready to install. All necessary mounting hardware and caliper adapters are included. This kit does not include brake fluid; OEM brake lines are replaced by the included stainless steel lines.
