Brembo 1ND.9523A1 GT Series Big Brake Kit 6-Piston Monobloc 405x34mm 2-Piece Rotor Black Caliper

The Brembo 1ND.9523A1 is a front axle GT Series Big Brake Kit (BBK) featuring a 6-piston cast monobloc radial-mounted caliper finished in black, paired with 405mm x 34mm 2-piece rotors. Engineered from decades of motorsport development, this complete kit delivers a significant upgrade in thermal capacity, stopping power, and pedal feel over the OEM braking system.

Key Features:

• 6-Piston Cast Monobloc Caliper (Black): Machined from a single billet of cast aluminum for exceptional rigidity and minimal deformation under repeated, high-intensity braking
• 405mm x 34mm 2-Piece Floating Rotors: Lightweight 2-piece construction with an aluminum alloy bell reduces unsprung weight for improved suspension dynamics and handling
• Exclusive Venting System: Directionally vented disc design enhances cooling capacity and reduces the risk of thermal shock cracking by up to 40%
• High-Performance Brake Pads Included: Formulated with specific friction materials engineered for both street and track demands, outlasting standard OEM pads
• TUV/DOT Homologated Metal-Braided Hoses: Stainless steel braided brake lines provide consistent, responsive pedal pressure and long-term durability
• Complete Hardware Kit: Includes Brembo-engineered CNC billet caliper adapters and all necessary fastener hardware for a straightforward installation
• Pre-Assembled: Ships ready to install, reducing setup time
• OEM ABS Compatible: Designed to work with the vehicle's factory brake master cylinder and ABS system without modification

The Brembo GT Series is the most popular high-performance braking upgrade for street-to-track use. The monobloc caliper construction ensures a stable, consistent brake pedal under extreme thermal loads, while the oversized 2-piece floating rotors dramatically reduce brake fade during repeated high-speed stops. The black caliper finish with the Brembo logo delivers an unmistakably aggressive appearance behind the wheel.
