Wilwood AERO4 Big Brake Rear Parking Brake Kits

Wilwood AERO4 Big Brake rear parking brake kits replace the factory disc brakes and use the OE parking brake assembly as a complement to front big brake upgrades on late model trucks, SUVs, and high performance vehicles. High-capacity braking from the AERO4 calipers (black or red powdercoat), high-friction BP compound pads, and oversized rotors (slotted or drilled/slotted) are matched to the OE master cylinder output, ABS function, and individual vehicle bias requirements. Wilwood AERO4 Big Brake rear parking brake kits provide enhanced brake performance, increased durability, and high-tech style to complement big wheel, tire, and suspension upgrades on customized vehicles and all others with increased brake requirements.
