Brembo 1N1.9550A1 GT Series Big Brake Kit

The Brembo 1N1.9550A1 is a complete GT Series Big Brake Kit engineered for high-performance street and track driving. Brembo's Gran Turismo brake systems are derived directly from motorsport technology, delivering the stopping power, fade resistance, and pedal feel that demanding drivers require.

Key Features:

• Multi-piston fixed aluminum calipers — constructed from lightweight aluminum alloy with opposed pistons for precise, even pad clamping and reduced brake fade
• Oversized cross-drilled or slotted rotors — made from a proprietary cast iron alloy for extended service life, with zinc coating for corrosion resistance and an attractive finish
• 2-piece floating rotor design — aluminum center hat with proprietary floating hardware (bobbins) allows radial and axial expansion under heat, preventing thermal distortion
• Twin seal caliper design — prevents dirt and debris from contaminating brake fluid, ensuring long-term reliability
• Differential piston bore sizing — sequentially sized pistons promote even brake pad wear across the full friction surface
• Stainless steel braided brake lines — reduce fluid absorption for consistent, firm pedal feel and improved modulation
• High-performance brake pads included — application-specific friction compound for optimal street and track performance
• Compatible with factory ABS and traction control systems — drop-in upgrade with no modifications to OEM electronics required
• 2-year warranty against manufacturing defects

The Brembo GT Big Brake Kit is sold as a complete axle set with all necessary hardware included, making installation straightforward for experienced technicians. As with all Brembo GT kits, wheel clearance verification is required prior to installation — typically 17" or larger wheels are needed to accommodate the larger rotor diameter.
