Rear Disc Brake Kit 12- Bolt Chevy w/Parking Brk

The Rear Disc Brake Kit 12-Bolt Chevy w/Parking Brk from Wilwood represents a modern solution for classic and restomod Chevrolet muscle cars, trucks, and performance builds from 1968–1996 model years. This complete rear brake assembly is engineered for drivers who demand stopping power, safety, and reliable parking brake functionality without compromise. Whether you're upgrading a vintage 12-bolt rear or building a high-performance street machine, this kit eliminates the guesswork of sourcing individual components and integrating legacy drum brake systems that fall short of modern safety standards.

The kit features a Dynapro low-profile design with 4-piston calipers and an 11-inch drilled and slotted iron rotor—geometry that maximizes brake surface area while minimizing unsprung weight and reducing thermal stress during sustained braking. The drilled and slotted rotor design promotes gas and dust evacuation, improving modulation and reducing fade during spirited driving or towing. Aluminum construction throughout reduces mass, and the black powder coat finish resists corrosion and maintains appearance in harsh road salt and moisture environments. The integrated offset hat and parking brake assembly provides mechanical holding force on grade or during extended stationary periods, critical for safety-conscious builds and daily drivers alike.

This rear disc brake kit is ideal for restorers, hot rod builders, and performance enthusiasts upgrading OEM drum brake systems to modern disc technology. Installation fits GM 12-bolt differentials across the specified model range and integrates seamlessly with existing driveline geometry. The complete assembly weighs 44.7 pounds and arrives ready for mounting—no additional fabrication or brake line custom work required for direct-bolt applications. Proper bedding-in of new rotor and pad surfaces is recommended before full-duty driving to ensure optimal bite and durability.
