The Big Ford New Style flange brackets and flared aluminum hats establish the 2.50-inch-offset installation, with BP-10 pads and electronic controls included.

Bill Wood founded the company in 1977; it is based in Camarillo, California, and serves motorsport, street-performance and specialized applications.\u003c\/p\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eFor Big Ford New Style rear axle flanges with the specified 2.50-inch offset. Confirm bearing diameter, axle register and flange bolt spacing with the linked worksheet, including on the listed 1990 Lincoln Town Car rear-drum application. This 12.88-inch version supplies separate electric parking calipers and their controller, switch and universal harness. Route and mount the electrical system as the instructions specify. It provides parking restraint, not emergency braking while the vehicle is moving. Purchase the service-brake flexlines separately and check the wheel template. Consult the fitment table below for the individual year, model and equipment details. 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\u003eTechnical Details\u003c\/h3\u003e\u003ch3\u003eCalipers and pads\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCalipers: XRS4R; 4 pistons\u003c\/li\u003e\n\u003cli\u003eCaliper finish: Red 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\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; 2.035-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\u003eKit contents and separate parts\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-18295-DR\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\u003cli\u003eElectric parking calipers, switch with pigtail, universal harness and control unit: included\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\/ds1682.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.
