{"product_id":"wilwood-120-8729","title":"Wilwood Anodized Powerlite Radial Caliper, 1.38-Inch Piston Bores and 0.86-Inch Rotor Opening","description":"\u003cp\u003eThe larger-bore Powerlite in this listing is the anodized four-piston version for a nominal 0.86-inch-wide rotor. Four 1.38-inch stainless pistons provide the published 3.00-square-inch piston area. It shares the compact radial format with other Powerlite models, but its hydraulic and rotor-width requirements must be matched explicitly. Based in Camarillo, California, Wilwood Engineering was founded by Bill Wood in 1977. The manufacturer produces disc brake systems and components for motorsport, street-performance and specialized applications, with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Individual components are chosen to suit the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-8729\u003c\/li\u003e\n\u003cli\u003eCaliper type: Powerlite Radial Mount\u003c\/li\u003e\n\u003cli\u003eConstruction: Forged Aluminium\u003c\/li\u003e\n\u003cli\u003eFinish: Type III Anodize\u003c\/li\u003e\n\u003cli\u003ePiston bores: 1.38 \/ 1.38 inches\u003c\/li\u003e\n\u003cli\u003ePiston type: Stainless\u003c\/li\u003e\n\u003cli\u003ePiston count: 4\u003c\/li\u003e\n\u003cli\u003ePublished piston area: 3.00 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 0.86 inch\u003c\/li\u003e\n\u003cli\u003eRotor thickness limits: 0.79–0.86 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter limits: 9.45–11.00 inches\u003c\/li\u003e\n\u003cli\u003eMounting style: Radial\u003c\/li\u003e\n\u003cli\u003eHandedness: Not restricted to one side; correct mounting and bleed orientation required\u003c\/li\u003e\n\u003cli\u003eMounting centers: 5.08 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole size: 0.40 inch\u003c\/li\u003e\n\u003cli\u003eMount height: 1.56 inch\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eRequired pad shape: 7912\u003c\/li\u003e\n\u003cli\u003ePublished pad area: 5 square inches\u003c\/li\u003e\n\u003cli\u003ePublished pad volume: 1.8 cubic inches\u003c\/li\u003e\n\u003cli\u003eManufacturer-listed component weight: 2.8 lb\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eCheck mounting centers and the 1.56-inch mount height against the receiving bracket.
