Wilwood 140-15034-DR Dynapro Radial-MC4 Rear Disc Brake Kit with Drilled Rotors

The Wilwood 140-15034-DR Dynapro Radial-MC4 Rear Axle Brake Kit is a direct replacement for factory rear disc brakes, engineered to complement front big brake upgrades on late-model high-performance and custom vehicles. Designed to work in harmony with OE master cylinders, ABS systems, and individual vehicle brake bias requirements, this kit delivers a significant upgrade in stopping power and durability without requiring major hydraulic system modifications.

At the heart of this kit are Wilwood's Dynapro Radial calipers, which feature a radial-mount design for increased stiffness and more consistent pad contact. The integrated MC4 parking brake assembly retains full parking brake functionality, making this a complete, street-legal rear brake solution. Paired with BP-10 compound brake pads and oversized 12.88" drilled rotors, the kit provides high-capacity braking performance well beyond OEM levels.

Key Features:

• Dynapro Radial calipers with radial-mount design for superior rigidity and brake feel
• Integrated MC4 parking brake assembly for full parking brake retention
• BP-10 brake pad compound for high-performance street and track use
• Oversized 12.88" drilled rotors for increased thermal capacity and fade resistance
• Compatible with OE master cylinder output and ABS function
• Engineered to match factory brake bias requirements
• Ideal complement to front big brake upgrade (BBK) systems
• Drilled rotor finish (-DR suffix) for enhanced cooling and visual appeal

This kit is an excellent choice for customized vehicles running large wheel, tire, and suspension upgrades, as well as any application with elevated braking demands. All components are engineered and manufactured by Wilwood in the USA to exacting tolerances for reliable, repeatable performance.
