{"product_id":"wilwood-120-15737","title":"Wilwood Powerlite-ST Brake Caliper, Anodized — 1.38\/1.38-Inch Bores, 0.86-Inch Rotor Width","description":"\u003cp\u003eWilwood supplies this Powerlite-ST brake caliper with an anodized finish. Its 5.08-inch mounting span and 0.86-inch-wide rotor configuration are key checks when selecting a single caliper for an existing system. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among the disc brake components designed and manufactured by Wilwood Engineering. Bill Wood founded the company in 1977; it is based in Camarillo, California. The range serves motorsport, street-performance and specialized systems, with component selection determined by the full brake arrangement. Powerlite-ST uses a compact radial-mount body with Thermlock insulated pistons and top-supported 7912-shape pads. The bore size must be selected with the master cylinder and hydraulic balance; nominal rotor width is independent of rotor diameter and wheel diameter.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-15737\u003c\/li\u003e\n\u003cli\u003eComponent: Powerlite Radial Mount; one individual caliper\u003c\/li\u003e\n\u003cli\u003ePlacement: Universal mounting orientation; verify axle position\u003c\/li\u003e\n\u003cli\u003eConstruction and finish: Forged aluminum; Type III Anodize\u003c\/li\u003e\n\u003cli\u003ePistons: 4; Thermlock insulated; bore dimensions 1.38\/1.38 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic piston area: 3.00 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eBrake pad shape: 7912; shape number does not specify a friction compound\u003c\/li\u003e\n\u003cli\u003eMounting interface: Radial; mounting centers 5.08 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole diameter: 0.40 inches\u003c\/li\u003e\n\u003cli\u003eMount height: 1.56 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 0.86 inches\u003c\/li\u003e\n\u003cli\u003eRotor width range: 0.79–0.86 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter range: 9.45–11.00 inches\u003c\/li\u003e\n\u003cli\u003eCaliper weight reference: 2.8 lb\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eMatch the 5.08-inch radial attachment to the existing bracket, then check caliper centering over the 0.86-inch nominal-width rotor. Axle placement is determined by the engineered brake package, not by a generic caliper designation. The 1\/8-27 NPT connection must use the correct fitting and seal. Check the full wheel envelope with the actual bracket and rotor installed.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.wilwood.com\/Calipers\/CaliperProd?itemno=120-15737\"\u003eWilwood caliper specifications\u003c\/a\u003e · \u003ca href=\"https:\/\/www.wilwood.com\/PDF\/Flyers\/fl147.pdf\"\u003eWilwood technical reference\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003ePMB Performance has over 20 years of experience with parts and brake fitment.
