Brembo 1L3.9003AS GT-S Front Brake Kit Black Anodized - 380x34mm 6-Piston

The Brembo 1L3.9003AS is a complete front axle GT-S Series Big Brake Kit featuring 6-piston cast monobloc radial mounted calipers and 380mm x 34mm 2-piece slotted Type-3 discs. This advanced GT-S system includes racing-style caliper radiators, dual inner piston seals, an inner pressure seal, and an outer wiper seal for optimal performance and long-lasting track use. The calipers feature a hard anodized black finish with machined Brembo logo in red for superior corrosion resistance and longevity.

Key Features:

• Cast monobloc 6-piston radial mounted caliper body
• 380mm x 34mm (15 inch) Type-3 slotted 2-piece vented discs
• Directionally vented and slotted rotors continuously clean and refresh pad surface
• Lightweight 2-piece disc design increases thermal capacity to dramatically reduce brake fade
• High-performance pads with application-specific friction materials included
• Homologated metal braided brake lines with adapters
• All necessary mounting hardware and CNC billet caliper adapters included
• Ships pre-assembled for ease of installation

The braking system's primary function is to dissipate heat, and these larger, more sophisticated discs increase the fade resistance of the system significantly over factory components. The 2-piece floating disc design allows the rotor to remain in line with the caliper even under extreme conditions such as hard cornering. The GT-S Series features opposed piston calipers designed for high thermal resistance and precise brake modulation, making it the ultimate brake upgrade for street and track use.
