The Wilwood AERO4 rear parking-brake axle kit with drilled 14.00in rotors is intended for 2005–2014 Mustang rear applications, replacing factory discs and integrating the OE parking brake assembly. Designed to match OE master cylinder output and ABS bias, the kit combines radial-mount AERO4 calipers and BP compound pads with oversized rotors to enhance braking performance, durability, and modern visual appeal on modified Mustangs.
