{"product_id":"wilwood-260-14389-bk","title":"Wilwood Black 1-1\/8-inch Tandem Master with Manual Pushrod and Remote Reservoir Kit","description":"\u003cp\u003eA one-and-one-eighth-inch bore and included threaded rod identify this black pushrod-equipped Remote Tandem master. Its pair of seven-ounce reservoirs supplies the two chambers through separate low-pressure feeds instead of a cast-in reservoir above the housing. Founded in 1977 by Bill Wood, Wilwood Engineering carries out disc brake design and manufacturing from Camarillo, California. Its rotors, calipers, brake lines, master cylinders, fittings and valves serve motorsport, street-performance and specialized applications. Parts within that range must be matched to one another and to the requirements of the complete braking system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 260-14389-BK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum \/ Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinder bore:\u003c\/strong\u003e 1-1\/8\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure circuits:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReservoir Type:\u003c\/strong\u003e Remote\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFluid capacity:\u003c\/strong\u003e 7.0 \/ 7.0 oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange-to-end length:\u003c\/strong\u003e 6.56\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting centers:\u003c\/strong\u003e 3.22–3.40\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePushrod dimensions:\u003c\/strong\u003e 4.23\" x 3\/8-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black E-coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNative pressure ports:\u003c\/strong\u003e 1\/2-20 at both circuits; use the correct included outlet adapters and seal washers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit outlet adapters:\u003c\/strong\u003e Primary: 3\/8-24 or 1\/2-20 inverted flare; secondary: 3\/8-24 or 9\/16-18 inverted flare\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydraulic relationship:\u003c\/strong\u003e Equal pressure output from the two circuits before external proportioning; 2:1 primary\/secondary volume relationship\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService:\u003c\/strong\u003e Factory rebuild only; do not disassemble the tandem piston assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTravel check:\u003c\/strong\u003e DS-1189 specifies 1.12-inch stroke and also states 1.10 inches in its full-travel warning; verify actual full piston travel before the pedal reaches a stop\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReservoir feed:\u003c\/strong\u003e 0.87-inch inlet seating diameter with 11\/16-20 internal thread; 1\/4-inch feed-hose adapters for the standard remote reservoirs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReservoir package:\u003c\/strong\u003e Two 7 oz reservoirs with caps, brackets, clamps, hoses and feed adapters for direct or remote mounting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing envelope:\u003c\/strong\u003e 7.16 inches as listed, excluding the projecting operating rod; verify the complete rod-equipped length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eProvide sufficient room for the complete rod-equipped assembly and allow full, unimpeded piston motion.
