{"product_id":"wilwood-140-18293-d","title":"Big Ford New Style 2.50-inch Offset: Wilwood 12.88-inch Drilled\/Slotted Rear Disc and Parking Brakes with Black XRS4R Calipers","description":"\u003cp\u003eBlack XRS4R calipers clamp 12.88-inch drilled\/slotted rotors in this Big Ford rear conversion. The rotor hats house mechanical parking shoes; their cables and attachment hardware are selected separately to suit the vehicle's lever and routing. Bill Wood established Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003ch3\u003eKit contents and separate parts\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-18293-D\u003c\/li\u003e\n\u003cli\u003eSupply: one brake kit; components for both sides of the axle\u003c\/li\u003e\n\u003cli\u003eMounting hardware: included\u003c\/li\u003e\n\u003cli\u003eHubs: not included\u003c\/li\u003e\n\u003cli\u003eSpindles, master cylinder and brake booster: not included\u003c\/li\u003e\n\u003cli\u003eBrake flexlines: not included\u003c\/li\u003e\n\u003cli\u003eAxle housing flange: Big Ford New Style\u003c\/li\u003e\n\u003cli\u003eRequired axle\/hub offset: 2.50 in; 63.5 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eMeasure the rear housing before selecting this 12.88-inch XRS4R package: it requires a Big Ford New Style flange and a 2.50-inch axle offset. Use the manufacturer's worksheet to compare the flange bolt layout, bearing diameter and axle register. The 1990 Lincoln Town Car rear-drum application in the table remains subject to those measurements. The rotor hats contain an internal-shoe parking brake. Cables, clevis hardware, adapters and hydraulic flexlines must be supplied separately; a universal cable set may require changes to the vehicle or routing. Nominal minimum wheel diameter: 17 in; 431.8 mm. The linked wheel-clearance diagram must confirm barrel and spoke clearance; wheel diameter alone does not guarantee fit.\u003c\/p\u003e\u003ch3\u003eRotors and mounting dimensions\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRotors: 12.88 in; 327.15 mm diameter x 1.10 in; 27.94 mm thick; vented Spec-37 Iron\u003c\/li\u003e\n\u003cli\u003eFriction faces: SRP Drilled \u0026amp; Slotted\u003c\/li\u003e\n\u003cli\u003eRotor coating\/finish: Black Electro Coat\u003c\/li\u003e\n\u003cli\u003eInternal vanes: 48 curved\u003c\/li\u003e\n\u003cli\u003eHats: Aluminum; Black E-Coat; 1.540-inch hat offset\u003c\/li\u003e\n\u003cli\u003eRotor\/hat wheel-stud clearance patterns: 5 x 4.5 in; 5 x 114.3 mm; 5 x 4.75 in; 5 x 120.65 mm; 5 x 5 in; 5 x 127 mm\u003c\/li\u003e\n\u003cli\u003eStud specification: 1\/2-inch wheel studs (hat clearance; verify existing axle studs)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCalipers and pads\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCalipers: XRS4R; 4 pistons\u003c\/li\u003e\n\u003cli\u003eCaliper finish: Black Powder Coat\u003c\/li\u003e\n\u003cli\u003eBody construction: Forged aluminum\u003c\/li\u003e\n\u003cli\u003ePistons: stainless\u003c\/li\u003e\n\u003cli\u003eMounting: radial\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eIncluded pad compound: BP-10\u003c\/li\u003e\n\u003cli\u003eListed piston bore sizes: 1.12 \/ 1.12 in\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eInstallation documents\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.wilwood.com\/PDF\/DataSheets\/ds1681.pdf\"\u003eInstallation instructions\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.wilwood.com\/Images\/BrakeKits\/Axle-Offset-Worksheet-Wilwood.pdf\"\u003eTechnical bulletin\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWARNING: This product can expose you to chemicals including Arsenic, Cadmium, Chromium (Hexavalent compounds), Lead, Nickel, Cobalt and Antimony Trioxide which are known to the State of California to cause cancer or other reproductive harm.
