Why Choose Our 4-Piston Forged Rear Brake Kit?

• Forged 4-Piston Calipers: Crafted from premium T6-6066 forged aluminum, our calipers deliver exceptional strength and heat resistance—far surpassing standard cast designs. Heat-treated for durability and featuring a precision-tuned piston setup—28.6mm and 38.1mm radii, with a total piston area of 28.71 cm²—these calipers ensure balanced, reliable braking performance.
• 355mm 2-Piece Ventilated Rotors: Engineered for optimal heat dissipation, our high-carbon steel 2-piece rotors feature lightweight aluminum hats for reduced weight and enhanced durability. With directional curved veins and a cross-hatch groove design, they sweep heat and debris away, maintaining consistent rear braking under demanding conditions.
• Enhanced Rear Control: Four pistons work seamlessly across a 57.4 cm² pad area, delivering precise brake modulation and stability—ideal for off-roading, heavy loads, or dynamic driving.
• Designed for Your Ride: Precision-engineered to fit the Prado 250, Land Cruiser 300, and GX550 (6 x 139.7 stud pattern), this bolt-on kit adapts perfectly to the original electronic handbrake with no loss of functionality. Specifically designed to fit standard 18” and 20” wheels, as well as aftermarket wheels (check fitment for specifics).
