The Wilwood AERO4 rear parking-brake axle kit swaps factory discs for radial-mount AERO4 calipers and oversized 14.00in drilled rotors, using the OE parking brake assembly to complement front big-brake upgrades. Matched to OE master cylinder output and ABS, the kit pairs high-friction BP compound pads with robust hardware to improve brake capacity and durability while offering a modern appearance that suits big wheel, tire, and suspension modifications.
