Wilwood 140-14089-R Dynapro Radial-MC4 Rear Disc Brake Kit with Parking Brake 11" Slotted Rotor Red Caliper

The Wilwood 140-14089-R Dynapro Radial-MC4 Rear Axle Brake Kit is a direct replacement for factory rear disc brakes on late-model high-performance vehicles. Designed with an integrated MC4 mechanical parking brake assembly, this kit is an ideal complement to front big brake upgrades, delivering a balanced and powerful braking system from front to rear.

At the heart of the kit are Dynapro Radial 4-piston calipers finished in red powdercoat, paired with oversized 11.00" slotted rotors and high-performance BP-10 compound brake pads. The complete system is engineered to match OE master cylinder output, maintain proper ABS function, and satisfy individual vehicle brake bias requirements — ensuring predictable, high-capacity stopping power without requiring hydraulic system modifications.

Key Features:

• Dynapro Radial 4-piston calipers in red powdercoat finish
• 11.00" slotted rotors for enhanced heat dissipation and fade resistance
• BP-10 compound brake pads for high-friction street performance
• Integrated MC4 mechanical parking brake assembly — no separate parking brake caliper required
• Compatible with Ford 8.8" IRS rear axle applications
• Engineered to maintain OE master cylinder, ABS, and brake bias compatibility
• Complements big wheel, tire, and suspension upgrades on custom and high-performance builds
• Complete bolt-on kit for straightforward installation

Note: Brake lines are not included. Wilwood Flexline brake hoses must be ordered separately to complete the installation.

The Wilwood 140-14089-R delivers the stopping performance, durability, and aggressive styling demanded by customized street machines and performance vehicles with elevated braking requirements.
