Wilwood 140-14640-D Dynapro Radial-MC4 Rear Parking Brake Kit with 12.19" Rotors

The Wilwood 140-14640-D Dynapro Radial-MC4 Rear Parking Brake Kit is a complete bolt-on rear disc brake upgrade engineered for late-model high-performance vehicles. This kit replaces the factory rear disc brakes and integrates the MC4 mechanical parking brake assembly, making it an ideal complement to front big brake upgrades where a separate, mechanically actuated emergency brake caliper is required.

At the heart of this kit are the Dynapro Radial four-piston calipers, paired with BP-10 compound brake pads and oversized 12.19" rotors. The complete system is engineered to work in harmony with your OE master cylinder output, factory ABS function, and individual vehicle front-to-rear brake bias requirements — delivering high-capacity stopping power without requiring a master cylinder swap or ABS recalibration.

Key Features:

• Dynapro Radial four-piston calipers — forged billet aluminum construction for strength and reduced weight
• MC4 integrated parking brake assembly — mechanical actuation for reliable emergency/parking brake function
• 12.19" oversized rotors — increased thermal capacity and braking surface over factory rotors
• BP-10 compound brake pads — high-performance friction material matched to the caliper and rotor specifications
• OE-compatible design — engineered to work with factory master cylinder output and ABS systems
• Bolt-on installation — designed to install using common hand tools without major modifications
• High-tech appearance — complements big wheel, tire, and suspension upgrades on custom builds

The Wilwood 140-14640-D is an excellent solution for custom vehicles and performance builds with elevated braking demands. The kit provides enhanced stopping performance, long-term durability, and a premium look that stands up to the most aggressive wheel and suspension setups.
