Product details
This anodized D52 replaces a dimensionally matching GM-style single-piston floating caliper with a two-piston forged aluminum design. Two 2.00-inch stainless pistons provide the larger 6.28-square-inch configuration for a nominal 1.28-inch-wide rotor. Bill Wood established Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc brake systems, from calipers and brake rotors to master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized use.
Technical Details
- Manufacturer part number: 120-10936. Component: D52 Dual Piston Floater caliper.
- Supply: one brake caliper, not a complete axle brake kit. Match the mating rotor, pads, bracket and connection hardware to the installation.
- Hydraulic inlet thread: 7/16-20. Use a fitting with the correct thread and sealing seat.
- Bore configuration 2.00 inches across 2 pistons; piston material: stainless steel. Hydraulic effective area: 6.28 square inches.
- Pad fit is type D52. Match the pad dimensions and compound to the rotor and intended braking conditions.
- Caliper weight: approximately 5.5 lb.
- Piston dust boots: not fitted.
- Construction and surface: forged aluminum housing finished in Type III anodize.
- Nominal rotor width 1.28 inch; compatible outside diameter from 11.00 through 12.19 inches. Specified rotor-width limits: 1.19–1.28 inch.
- Bracket interface: 7.06-inch floating centers with 0.69-inch holes. Specified mount height: 0.77 inches; orientation: universal.
Fitment & Compatibility
Compare the vehicle's actual D52 bracket and rotor instead of assuming all GM brakes use the same dimensions. The 7/16-20 banjo port may require a different line on vehicles originally using a metric hose connection.
With 20+ years of experience, PMB Performance can help compare the actual brake hardware. Supply the caliper number, rotor dimensions and mounting measurements when asking about compatibility.
