Wilwood 05-Up Mustang AERO4 Big Brake Rear Parking Brake Kit

Upgrade the rear braking system of your 2005-Up Ford Mustang with the Wilwood AERO4 Big Brake Rear Parking Brake Kit. Designed as a high-performance rear brake upgrade, this system combines powerful AERO4 four-piston radial-mount calipers with oversized 14.00-inch two-piece rotors and an integrated parking brake system.

The AERO4 calipers provide increased braking capacity and durability for high-performance street, custom, and track-oriented Mustang applications. The four-piston design uses stainless steel pistons and Wilwood high-performance brake pads to provide balanced rear braking performance designed to complement a front big brake upgrade.

A neatly concealed internal shoe-style parking brake system provides reliable static holding power while maintaining a clean installation. This allows the kit to retain functional parking brake capability while providing the performance and appearance of a large-diameter rear disc brake system.

The kit is available with either GT slotted or SRP drilled and slotted rotors along with black or red powder-coated calipers, allowing the brake system to be matched to the appearance and performance requirements of the vehicle.
