Brembo 1Q1.9639A5 GT Series Big Brake Kit Yellow Caliper - 8-Piston

The Brembo 1Q1.9639A5 is a complete Gran Turismo (GT) Series Big Brake Kit featuring Brembo's iconic 8-piston cast monobloc caliper finished in striking yellow powder coat. Engineered for high-performance street and track use, this big brake upgrade delivers dramatically increased braking torque, thermal capacity, and pedal feel over factory brake systems.

Brembo GT Series kits are built around radial-mounted fixed calipers paired with oversized 2-piece ventilated discs. The two-piece rotor design allows a controlled amount of radial and axial float to prevent thermal distortion under repeated hard braking, while also reducing unsprung rotational mass for improved handling response.

Key Features:

• 8-Piston Cast Monobloc Caliper — radial-mounted fixed caliper machined from aluminum alloy for maximum rigidity and heat dissipation
• Yellow Powder-Coat Finish — A5 color designation; delivers a bold, race-inspired appearance
• Differential Piston Bores — eliminates pad taper wear for even, consistent pad contact across the rotor face
• Twin Seal Design — protects caliper internals from dirt, debris, and brake fluid contamination
• 2-Piece Oversized Rotor — increases braking torque and thermal capacity while resisting heat-induced warping
• Compatible with Factory ABS and Traction Control — seamless integration with OEM safety systems
• Complete Kit — includes calipers, rotors, high-performance brake pads, metal-braided stainless steel brake lines, mounting brackets, and all necessary hardware

Brembo GT Series big brake kits are designed for vehicles at original (stock) ride height. Lifted or lowered suspensions may affect brake line compatibility. Wheel clearance should be verified prior to installation using Brembo's application-specific clearance guide — most installations require a minimum 17-inch wheel. All Brembo GT kits are backed by a 2-year warranty.
