{"product_id":"wilwood-260-18184-bk","title":"Wilwood Black 15\/16-inch High-Volume Master Cylinder, Tandem Reservoir, No Rod","description":"\u003cp\u003eBlack e-coat finishes this high-volume tandem master, supplied without a pedal pushrod. The fifteen-sixteenths-inch bore gives it a different hydraulic requirement from the one-inch and larger rodless versions despite a familiar oval reservoir shape. Wilwood Engineering serves motorsport, specialized and street-performance applications through disc brake system design and manufacturing. Bill Wood founded the company in 1977, and it is based in Camarillo, California. The range spans valves, rotors, fittings, calipers, brake lines and master cylinders; the installed braking assembly determines the appropriate combination of parts.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 260-18184-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 15\/16\"\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFluid capacity:\u003c\/strong\u003e 8.0 \/ 4.8 oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange-to-end length:\u003c\/strong\u003e 8.15\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length:\u003c\/strong\u003e 8.76\"\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\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\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eVerify the existing manual or assisted actuator reaches the piston recess correctly without preload.
