1982–1987 GM G-Body Wilwood D52 Black Caliper Brake Refresher Kit

9" Power Booster • Wilwood 1" Master Cylinder • Cross-Drilled & Slotted Rotors

Give your G-body's original front disc brakes a complete performance refresh with a combination of genuine Wilwood components and brand-new supporting brake hardware from Pirate Jack.

The centerpiece is a set of genuine Wilwood D52 dual-piston red powder-coated calipers (P/N 140-11291-RD). You get the Wilwood name, the red finish and the aggressive look behind the wheels—along with a complete collection of new components to replace the wear items that have accumulated over decades of driving.

This is more than a caliper upgrade. It's a complete front brake refresher package, including the power booster, master cylinder, proportioning valve, calipers, performance rotors, braided hoses and front wheel-end components.

Genuine Wilwood D52 Black Calipers

The star of this package is a genuine set of Wilwood D52 dual-piston calipers.

• Wilwood P/N 140-11291-BK
• Genuine Wilwood calipers
• Dual-piston D52 design
• Red powder-coated finish
• Wilwood logo
• Brake pads and caliper hardware included
• A dramatic upgrade in appearance over the original factory calipers

These are the real Wilwood calipers, not a generic caliper with a Wilwood-style appearance.

Complete Front Brake Refresh

Along with the Wilwood calipers, we've assembled the major components needed to give your G-body's front braking system a thorough overhaul:

• 9" dual-diaphragm power brake booster
• Wilwood 1" bore black master cylinder — P/N 260-8555-BK
• Black disc/drum proportioning valve
• Pair of 11" cross-drilled and slotted front rotors
• Pair of 7/16" stainless-steel braided brake hoses
• New front wheel bearings
• New grease seals
• New dust caps
• Caliper pads and mounting hardware

The result is a fresh combination of braking components rather than simply replacing one worn part at a time.

The Wilwood Difference

The Wilwood D52 dual-piston calipers give the front of your G-body a distinctly upgraded appearance while providing a modern performance-oriented caliper design.

Pair that with the Wilwood 1" bore master cylinder, a new 9" power booster and stainless braided hoses, and you've got a substantially refreshed hydraulic and mechanical braking system.

The cross-drilled and slotted rotors finish off the package with a performance look that looks right behind aftermarket wheels or a restored set of factory-style wheels.

Clean, Coordinated Under-Hood Appearance

We've also paid attention to the parts you see when you open the hood.

The black 9" booster, black Wilwood master cylinder and black proportioning valve create a clean, coordinated appearance without turning the engine compartment into a collection of mismatched components.

Why Replace Everything at Once?

A G-body that's been on the road for 40 years can have more than just worn-out calipers.

Brake hoses deteriorate. Wheel bearings accumulate miles. Grease seals harden. Master cylinders and boosters age. Original calipers can become less effective. Replacing these components individually can leave you with a mixture of old and new parts throughout the braking system.

This package gives you an opportunity to refresh the front braking system as a complete assembly.

Important Fitment Information

This kit is designed as a front brake refresher and upgrade for G-body vehicles that are already equipped with factory-style front power disc brakes.

This is not a drum-to-disc conversion kit.

Please verify your vehicle's existing brake configuration and application before ordering. Because brakes are a safety-critical system, professional installation is recommended.
