Wilwood 140-15138-D Dynapro Radial-MC4 Rear Disc Brake Kit 12.88" Black Drilled

The Wilwood 140-15138-D is a Dynapro 4 Radial-MC4 rear axle disc brake kit engineered as a high-capacity replacement for factory rear disc brakes. Designed to complement front big brake upgrades, this kit integrates the MC4 parking brake assembly for a complete, street-ready rear braking solution on late-model high-performance vehicles.

At the heart of this kit are Wilwood's Dynapro Radial four-piston calipers finished in black, paired with BP-10 compound brake pads and oversized 12.88" drilled rotors. The system is calibrated to work seamlessly with the OE master cylinder output, factory ABS function, and individual vehicle brake bias requirements—delivering a direct-bolt-on upgrade without compromising stock braking balance.
