Its finned four-ounce reservoir mounts directly to the master body, which uses a vertical flange and threaded pushrod. Since its founding by Bill Wood in 1977, Wilwood Engineering has designed and manufactured disc brake systems. Its Camarillo, California operation supplies master cylinders, brake lines, valves, rotors, fittings and calipers for specialized applications as well as motorsport and street-performance vehicles. Replacement and conversion parts need to match the complete braking arrangement.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 261-17277-.81\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum master body and billet aluminum reservoir\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinder bore:\u003c\/strong\u003e 13\/16\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure circuits:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStroke Length:\u003c\/strong\u003e 1.12 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eListed displacement per stroke:\u003c\/strong\u003e 0.58 cu in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReservoir Type:\u003c\/strong\u003e Direct-mounted reservoir on Compact Remote cylinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFluid capacity:\u003c\/strong\u003e 4.00 oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange-to-end length:\u003c\/strong\u003e 3.37\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length:\u003c\/strong\u003e 7.80\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting centers:\u003c\/strong\u003e 2.25\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePushrod dimensions:\u003c\/strong\u003e 4.00\" x 5\/16-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black E-coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet arrangement:\u003c\/strong\u003e 0.87-inch seating diameter with 11\/16-20 internal thread; this is the reservoir feed, not the pressure outlet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure connection:\u003c\/strong\u003e 1\/8-27 NPT outlet; select the appropriate pressure-line adapter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReservoir package:\u003c\/strong\u003e One directly mounted 4 oz Type III hard-anodized finned billet reservoir with cap and seals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eVerify bore selection and pedal alignment.
