{"product_id":"wilwood-261-14961-bk","title":"Wilwood Left Combination Valve Package with Black Compact 7\/8-inch Master Cylinder and Manual Rod","description":"\u003cp\u003eThe 6.55-inch flange-to-end body makes this black 7\/8-inch tandem kit useful where the longer High Volume housing will not fit. It includes the manual pushrod and a left-hand combination valve with the formed connecting tubes and mounting hardware. Based in Camarillo, California, Wilwood Engineering has designed and manufactured disc brake systems since Bill Wood founded the company in 1977. Its fittings, valves, calipers, brake lines, master cylinders and rotors are used across motorsport, street-performance and specialized applications. Matching a component means checking both its own specification and the braking assembly around it.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 261-14961-BK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinder bore:\u003c\/strong\u003e 7\/8\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure circuits:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStroke Length:\u003c\/strong\u003e 1.10 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReservoir Type:\u003c\/strong\u003e Integral tandem chambers, 7.8 and 4.7 oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFluid capacity:\u003c\/strong\u003e 7.8 \/ 4.7 oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange-to-end length:\u003c\/strong\u003e 6.55\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length:\u003c\/strong\u003e 10.93\"\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 4.38\" 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\u003eKit contents:\u003c\/strong\u003e Master cylinder, left-side combination proportioning valve and bracket, formed stainless connecting tubes and mounting hardware\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCombination-valve functions:\u003c\/strong\u003e Adjustable rear pressure, isolated front\/rear circuits, front-line junction and hydraulic brake-light switch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eCheck the 3.22–3.40-inch flange and 3\/8-24 clevis connection against the actual pedal.
