This red 4-piston component is selected by brake-system geometry rather than vehicle year alone. Founded in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering manufactures disc brake components for motorsport, street-performance and specialized uses. Its range covers calipers, rotors, master cylinders, valves, fittings and brake lines.\u003c\/p\u003e\u003cp\u003eThis narrow four-piston Dynapro uses a 4.75-inch radial pattern and type 7812 pads. The compact body must still clear the wheel and rotor hat, with the bracket locating the pad sweep correctly on the rotor.\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 120-14091-RD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent:\u003c\/strong\u003e Wilwood Narrow Dynapro Radial; one caliper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody and finish:\u003c\/strong\u003e Billet aluminum; Red Powder Coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDust boots:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston arrangement:\u003c\/strong\u003e 4 pistons; 1.12-inch bores; stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydraulic piston area:\u003c\/strong\u003e 1.98 square inches, as specified by Wilwood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e universal side configuration; Radial; 4.75-inch centers; 0.39-inch mounting holes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount height:\u003c\/strong\u003e 1.61 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFluid inlet:\u003c\/strong\u003e 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePad shape:\u003c\/strong\u003e Wilwood type 7812; compound selected separately\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor width:\u003c\/strong\u003e 0.81-inch nominal; 0.75–0.86-inch permitted range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor diameter range:\u003c\/strong\u003e 11.75–12.88 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eSelect pads by the specified friction shape and intended operating temperature.
