Across its motorsport, specialized and street-performance applications, the correct choice depends on the complete brake system rather than one dimension alone.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 261-17319-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\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\u003eOverall Length:\u003c\/strong\u003e 8.92\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting centers:\u003c\/strong\u003e 3.25 × 1.76\"\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\/16-20 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\u003cli\u003e\n\u003cstrong\u003eFlange-to-end references:\u003c\/strong\u003e Exact product page: 6.55 inches; DS-1520 dimensional drawing: 6.70 inches.
