{"product_id":"wilwood-140-13928-r","title":"Wilwood Front Red D8-4 Conversion, 12.19-Inch Rotors for 1976–1977 Ford Bronco Disc Spindles","description":"\u003cp\u003eRed four-piston D8-4 calipers clamp the 12.19 by 1.25-inch plain rotors in this Bronco conversion. Ford disc-spindle geometry is required; a Bronco fitted with GM brake or spindle parts does not qualify. Established in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering designs and manufactures disc brake systems. Its master cylinders, calipers, brake rotors, lines, fittings and valves support motorsport, street-performance and specialized applications, with each component selected for its role in the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: Wilwood\u003c\/li\u003e\n\u003cli\u003eManufacturer part number: 140-13928-R\u003c\/li\u003e\n\u003cli\u003eKit classification: Front Brake Kits - Street Performance\u003c\/li\u003e\n\u003cli\u003eAxle position: Front Kits\u003c\/li\u003e\n\u003cli\u003eBrake Type: Disc\u003c\/li\u003e\n\u003cli\u003eSelling unit: Sold as a kit.\u003c\/li\u003e\n\u003cli\u003eRotor Outside Diameter: 12.19 in; 309.63 mm\u003c\/li\u003e\n\u003cli\u003eRotor Thickness: 1.25 in; 31.75 mm\u003c\/li\u003e\n\u003cli\u003eRotor Material: Iron\u003c\/li\u003e\n\u003cli\u003eSurface Type: Plain Face\u003c\/li\u003e\n\u003cli\u003eRotor construction: Vented\u003c\/li\u003e\n\u003cli\u003eBolt Circle Diameter: 5 x 5.5 in; 5 x 139.7 mm\u003c\/li\u003e\n\u003cli\u003eCatalog stud \/ mounting-hole reference: 0.640 in; 16.26 mm\u003c\/li\u003e\n\u003cli\u003eRotor surface finish: Plain\u003c\/li\u003e\n\u003cli\u003eHat material: Aluminum\u003c\/li\u003e\n\u003cli\u003eHat finish: Black E-Coat\u003c\/li\u003e\n\u003cli\u003eHat offset dimension: 1.450 in\u003c\/li\u003e\n\u003cli\u003eMinimum wheel guidance (clearance drawing required): 16 in; 406.4 mm\u003c\/li\u003e\n\u003cli\u003eSpindle Included: No\u003c\/li\u003e\n\u003cli\u003eMounting Hardware Included: Yes\u003c\/li\u003e\n\u003cli\u003eSeparate wheel hubs included: No\u003c\/li\u003e\n\u003cli\u003eMaster Cylinder Included: No\u003c\/li\u003e\n\u003cli\u003eBrake Booster Included: No\u003c\/li\u003e\n\u003cli\u003eBrake Lines Included: Yes\u003c\/li\u003e\n\u003cli\u003ePistons per service caliper: 4\u003c\/li\u003e\n\u003cli\u003eService-caliper piston construction: Stainless\u003c\/li\u003e\n\u003cli\u003eService-caliper mount: Lug\u003c\/li\u003e\n\u003cli\u003eCaliper body construction: Forged aluminum\u003c\/li\u003e\n\u003cli\u003eCaliper Color: Red\u003c\/li\u003e\n\u003cli\u003eCaliper Finish: Red Powder Coat\u003c\/li\u003e\n\u003cli\u003eCaliper Inlet Port Diameter: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eCaliper family: D8-4\u003c\/li\u003e\n\u003cli\u003ePad compound: PM - ProMatrix\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eDS-1075 specifies the 1976–1977 Ford Bronco Dana 44 disc spindle.
