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

The Wilwood 140-14640 Dynapro Radial-MC4 Rear Parking Brake Kit is a complete bolt-on rear disc brake upgrade engineered to replace factory rear disc brakes on late-model, high-performance vehicles. Designed to work in conjunction with front big brake upgrades, this kit integrates seamlessly with the OE master cylinder output and ABS system while satisfying individual vehicle brake bias requirements.

At the heart of this kit are Wilwood's Dynapro Radial four-piston calipers, constructed from forged billet aluminum for exceptional strength and reduced weight. The MC4 parking brake assembly provides a mechanically actuated emergency brake function, making this kit an ideal solution for performance builds that require a dedicated parking brake system.

Key Features:

• Dynapro Radial four-piston forged billet aluminum calipers for high-capacity braking force
• Oversized 12.19" rotors deliver a significant upgrade over factory brake hardware
• BP-10 high-friction compound brake pads included for enhanced stopping power
• Integrated MC4 mechanical parking brake assembly — no separate e-brake caliper required
• Engineered to maintain compatibility with OE master cylinder output and ABS function
• Matched to individual vehicle brake bias requirements for balanced front-to-rear performance
• Available with cross-drilled, slotted, or combination rotor finishes
• Bolt-on installation using common hand tools — no custom fabrication required

This kit is purpose-built for customized vehicles and performance street builds that have upgraded wheels, tires, and suspension, and require proportionally increased braking performance to match. Wilwood's precisely engineered component groupings ensure all parts work together as a system for maximum reliability and braking consistency.
