Brembo 1TD.9028A1 GT Series Front Big Brake Kit 380mm Slotted 2-Piece Rotors 6-Piston Black Calipers

The Brembo 1TD.9028A1 is a front axle GT Series Big Brake Kit featuring slotted 2-piece 380mm rotors paired with 6-piston monobloc aluminum calipers in a black finish. Engineered from decades of motorsport experience, this complete brake upgrade delivers significantly improved stopping power, fade resistance, and pedal feel over factory brake systems.

At the heart of the kit are 6-piston monobloc aluminum calipers machined from a single cast aluminum billet for outstanding rigidity and minimal flex under extreme braking loads. The 2-piece floating rotor design combines a lightweight aluminum hat with a high-carbon cast iron braking surface, allowing thermal expansion and contraction to reduce the risk of warping under repeated high-heat stops.

The slotted rotor surface continuously cleans and rejuvenates the brake pad contact face, improving consistency and helping to evacuate heat, gases, and debris. The result is a braking system with superior bite and dramatically reduced brake fade compared to OEM components.
