PRODUCT DESCRIPTION
AERO4-MC4 Big Brake Rear Parking Brake Kit
AERO4-MC4 Big Brake Rear Parking Brake Kits replace the factory disc brakes and use the MC4 parking brake assembly as a complement to high-performance front brake upgrades on late-model vehicles. The high-capacity braking system of AERO4R calipers, BP-10 compound pads, and oversized 14.00" rotors are matched to the OE master cylinder output, ABS function, and brake bias requirements of each vehicle. Improved braking performance, increased durability, and high-tech styling complement custom vehicle wheel, tire, and suspension upgrades and any other vehicle with increased braking demands.
