Wilwood 140-14640-DR Dynapro Radial-MC4 Rear Parking Brake Kit with Drilled Rotors

The Wilwood 140-14640-DR Dynapro Radial-MC4 Rear Parking Brake Kit is a complete bolt-on rear disc brake upgrade engineered for late-model high-performance vehicles. Designed to complement front big brake upgrades, this kit replaces the factory rear disc brakes with a fully integrated system that includes the MC4 mechanical parking brake assembly — making it an ideal solution for applications requiring a separate, mechanically actuated emergency brake.

Key Features:

• Dynapro 4-Piston Radial Mount Calipers — Forged billet aluminum construction finished in red for high-tech, race-inspired appearance
• 12.19" Cross-Drilled & Slotted Rotors (309x20mm) — Oversized rotors improve thermal capacity, reduce brake fade, and enhance wet-weather performance
• BP-10 High-Performance Brake Pads — Compound matched for high-capacity braking that works in harmony with OE master cylinder output and ABS function
• MC4 Mechanical Parking Brake Assembly — Integrated parking brake mechanism meets OEM requirements without sacrificing performance
• OE-Compatible Engineering — Matched to factory master cylinder output, ABS function, and individual vehicle brake bias requirements
• Bolt-On Installation — Designed for straightforward installation using common hand tools

The Dynapro Radial-MC4 kit delivers enhanced braking performance and increased durability while providing the high-tech style to complement big wheel, tire, and suspension upgrades. Whether building a customized show vehicle or a dedicated performance street car, this kit provides the stopping power and aesthetics to match.
