{"product_id":"wilwood-261-17278-94","title":"Wilwood Single-Outlet Compact Master Cylinder with Body-Mounted Billet Reservoir, Black 15\/16-Inch Bore","description":"\u003cp\u003eA direct-mounted aluminum reservoir supplies the 15\/16-inch compact master in this package. The master has one hydraulic outlet, so the circuit arrangement must be selected to suit the complete pedal and brake installation. Wilwood Engineering, the Camarillo, California disc brake manufacturer founded by Bill Wood in 1977, designs and builds systems for specialized, motorsport and street-performance applications. The product range covers brake lines, valves, fittings, calipers, master cylinders and rotors. A replacement component must preserve the intended relationship between the system's hydraulic and mechanical parts.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 261-17278-.94\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 15\/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 0.77 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\u003eMatch the 15\/16-inch bore, vertical mounting flange and pushrod connection.
