Rear Disc Brake Kit w/Park Brake Chevy

The Wilwood Rear Disc Brake Kit with Park Brake for Chevy is a high-performance stopping system engineered for serious automotive builds where durability and modulation matter. Designed for Chevrolet vehicles equipped with GM 12-bolt rear axle assemblies, this rear brake conversion transforms factory drum braking into reliable hydraulic disc technology. Whether you're upgrading a vintage restoration, performance street machine, or off-road platform, this kit delivers the stopping power and fade resistance required for sustained driving or towing applications.

This system features a 4-piston aluminum caliper paired with a 12-inch drilled and slotted iron rotor, engineered to dissipate heat efficiently during extended braking cycles and maintain consistent pedal feel. The offset hat rotor design allows optimal clearance within tight rear-axle geometry while the black powder-coated aluminum construction resists corrosion in harsh environments. An integrated mechanical parking brake mechanism is included, ensuring reliable secondary holding force for stationary vehicle security—critical for trailers, hillside parking, or systems without electric brake controls.

Operators upgrading street rods, classic trucks, or performance vehicles with modern stopping capability will benefit from this bolt-on rear conversion. The kit is purpose-built for GM 12-bolt axle housings, ensuring direct fitment without frame or suspension modification. Installation requires standard brake line plumbing, caliper bracket mounting, and rotor hub adaptation—tasks well within the scope of experienced automotive technicians or dedicated builders. Weighing 55.41 lbs with compact dimensions of 17.6 x 16.8 x 19.5 inches, the complete assembly ships ready for bench inspection and installation planning.
