Its one-inch bore supplies two independent circuits from the integral reservoir, with optional outlet locations on both sides of the housing. Camarillo, California is home to Wilwood Engineering, founded in 1977 by Bill Wood. Its disc brake design and manufacturing range includes valves, master cylinders, calipers, brake lines, rotors and fittings for street-performance, specialized and motorsport use. These parts are selected together so the completed braking system has the required hydraulic and mechanical arrangement.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 260-15542-P\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 1.00\"\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 12.32\"\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 5.75\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Chrome powder 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 actual manual pedal against the Mustang-style geometry, including the master page's 1964–1972 reference.
