Upgrade rear braking performance with the Wilwood AERO4 Big Brake Rear Axle Kit, part number 140-11119-DR. Designed for select late-model high-performance vehicles, this system replaces the factory rear disc brakes while retaining the original-equipment parking brake assembly. It is an effective complement to a front big brake upgrade and provides the performance, durability, and visual appeal expected for customized street and performance applications.
The kit combines high-capacity Wilwood W4AR four-piston calipers, BP-10 compound brake pads, and oversized 14-inch drilled rotors. These components are engineered to work with the factory master cylinder output, anti-lock braking system function, and vehicle-specific brake-bias requirements. The result is responsive braking performance and consistent stopping capability without requiring changes to the vehicle’s original hydraulic balance or ABS operation.

Feature: Oversized 14-inch drilled rotors help improve heat management and braking consistency. Feature: Retains the OE parking brake assembly for convenient factory-style parking brake operation.
