{"product_id":"wilwood-140-7139-p","title":"Wilwood Plain Rear Parking Rotors with Polished Dynalite Calipers — 12.19-inch, Old Big Ford 2.36-inch Offset","description":"\u003cp\u003eA plain rotor face contrasts with polished calipers on the old-style Big Ford rear assembly. Its polished 4-piston calipers and 12.19-inch plain-face rotors are assembled around the requirements of Big Ford Old Style, 2.36-inch offset. Wilwood Engineering, founded by Bill Wood in 1977, designs and manufactures disc brake systems in Camarillo, California. The range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications, with each component chosen to suit the complete brake system.\u003c\/p\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eChoose this package by the old-style Big Ford housing end and the measured 2.36-inch axle offset. The word Ford alone is not sufficient: new-style\/Torino and Small Ford ends use different bracket arrangements. Compare the mounting flange with DS419 and measure from the axle flange using Wilwood’s worksheet before dismantling the existing brakes. The application list includes a 1990 Lincoln Town Car row, but a changed axle assembly must still satisfy the specified end and offset. This conversion provides rear service discs plus an independent internal-shoe parking brake. Plan the cable connection as part of the installation; the brake kit does not include the cable assembly or hydraulic flexlines. A matching wheel bolt circle is only one check and does not establish housing compatibility.\u003c\/p\u003e\u003cp\u003ePrint and use the manufacturer wheel template at its specified scale. Check the barrel, spoke shape and offset on the wheels that will actually be used.\u003c\/p\u003e\u003cp\u003eRead the full application entry below, including the brake, spindle and numbered-note fields that apply to that vehicle.\u003c\/p\u003e\u003ch3\u003ePackage and installation requirements\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eService braking uses the four-piston calipers.
