AERO4 big brake rear axle kits replace factory disc brakes and use OE parking brake assemblies for late model performance vehicles. Each kit includes AERO4 calipers, large diameter rotors, and BP-10 or BP-20 compound pads that are matched to specific OE master cylinder outputs, ABS function, and vehicle bias requirements. The AERO4 big brake kit integrates enhanced brake performance and durability with big wheel, tire, and suspension upgrades.
