{"product_id":"wilwood-120-8729-y","title":"Wilwood Yellow Powerlite Radial Brake Caliper, 1.38-Inch Pistons for 0.79–0.86-Inch rotor width","description":"\u003cp\u003eThe yellow Powerlite is the four-piston, 1.38-inch-bore version in the wider rotor configuration. It has a forged aluminum housing with a 5.08-inch radial mounting pattern and a 1\/8-27 NPT inlet. The color distinguishes the finish while the 0.79–0.86-inch thickness limits establish the required rotor package. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. Wilwood designs and manufactures disc brake systems and components, from calipers and brake rotors to master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications; selection depends on the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-8729-Y\u003c\/li\u003e\n\u003cli\u003eCaliper type: Powerlite Radial Mount\u003c\/li\u003e\n\u003cli\u003eConstruction: Forged Aluminium\u003c\/li\u003e\n\u003cli\u003eFinish: Yellow Powder Coat\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\u003eCompare the caliper dimensions with the bracket and wheel before selecting the yellow finish option.
