They work with 12.19 × 0.81-inch plain face rotors; the vehicle designation must be considered together with the mounting details below. Wilwood Engineering, founded by Bill Wood in 1977, is based in Camarillo, California. Its work covers the design and manufacture of disc-brake systems and components for specialized vehicles, motorsport and street-performance use. The product range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines; compatibility depends on the complete system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 140-17121-R; supplied as an axle kit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMachining prerequisite:\u003c\/strong\u003e Housing-flange material removal and two drilled holes required; follow the specific drawing and arrange qualified machine-shop work.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eParking brake:\u003c\/strong\u003e Internal shoe parking brake supplied; cables, cable hardware and adapters are separate.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor\/hat mounting-hole pattern:\u003c\/strong\u003e 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; cataloged hole clearances 0.52 in; 13.21 mm.
