{"product_id":"wilwood-140-13333-dr","title":"Wilwood Red Rear Superlite 4R Kit, 14-Inch Drilled\/Slotted Rotors with Parking Brake for Big Ford Bronco Ends","description":"\u003cp\u003eRed Superlite 4R calipers surround 14-inch drilled-and-slotted rotor rings in this Big Ford Bronco rear package. Each radial caliper contains four stainless pistons with 1.12-inch bores; the separate parking shoes act inside iron hats rather than through the service caliper. 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\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 140-13333-DR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication and package:\u003c\/strong\u003e Rear Brake Kits - Street Performance; Rear Kits; Disc; Parking; Sold as a kit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStud-hole \/ clearance provision:\u003c\/strong\u003e 0.640 in; 16.26 mm; diameter provision, not a thread designation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel diameter starting requirement:\u003c\/strong\u003e 18 in; 457.2 mm; verify the individual wheel against the installation drawing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear axle-end interface:\u003c\/strong\u003e Big Ford Bronco; axle\/flange offset 2.36 in; 59.94 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded mechanical components:\u003c\/strong\u003e Mounting hardware: Yes; hub(s): No; spindle(s): No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydraulic components supplied:\u003c\/strong\u003e Master cylinder: No; brake booster: No; brake lines: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecified pad compound:\u003c\/strong\u003e BP-10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeparate rotor-hat specification:\u003c\/strong\u003e Iron; Black E-Coat; offset 1.540 inch; part 170-13326\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor dimensions:\u003c\/strong\u003e 14.00 in; 355.6 mm outside diameter; 1.10 in; 27.94 mm thickness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor construction:\u003c\/strong\u003e Spec-37 Iron; Vented; SRP Drilled \u0026amp; Slotted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliper assembly:\u003c\/strong\u003e Forged Narrow Superlite 4R; 4 pistons per caliper; Forged Aluminium body; Radial mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston and finish specification:\u003c\/strong\u003e Stainless pistons; Red calipers; Red Powder Coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydraulic inlet:\u003c\/strong\u003e 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel bolt pattern(s):\u003c\/strong\u003e 5 x 5.5 in; 5 x 139.7 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eMeasure the installed axle before ordering: this bracket arrangement requires a Big Ford housing end and 2.36 inches between the wheel sides of the housing and axle flanges. Match the 5 x 5.50-inch wheel attachment and hat register, then use DS1028 to check the wheel profile. An 18-inch minimum wheel diameter alone does not establish clearance.\u003c\/p\u003e\u003cp\u003eMeasure the axle flange and register before mounting the brake: the flange must be no larger than 6.61 inches, with a 0.050-inch chamfer at 45 degrees. Use the instructions for the 2.88-inch register and its centering adapters as applicable, alongside the required offset and housing pattern.\u003c\/p\u003e\u003cp\u003eThe installation reference identifies Big Ford Bronco rear applications with 3300-lb axle\/11-inch drums for 1966–1975 and the listed 1976–1977 configurations.
