{"product_id":"wilwood-120-15735","title":"Wilwood Powerlite-ST Brake Caliper — Anodized, 5.08-Inch Radial Mount","description":"\u003cp\u003eThe anodized Wilwood Powerlite-ST is an individual brake caliper. It combines a 5.08-inch attachment span with 1.25\/1.25-inch piston bores; confirm the rotor centerline and 0.86-inch width configuration before installation. 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. For motorsport, street-performance and specialized braking applications, Wilwood Engineering designs and manufactures disc brake systems and their individual components. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood supplies a range encompassing calipers, rotors, master cylinders, valves, fittings and brake lines, all selected to match the complete system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-15735\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 1.25\/1.25 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic piston area: 2.46 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\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\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\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eCompare the caliper drawing with your radial bracket before ordering. The 5.08-inch mounting centers and 1.25\/1.25-inch bores must suit the installed rotor offset and hydraulic system. Axle placement is determined by the engineered brake package, not by a generic caliper designation. A suitable pad sweep and clearance inside the wheel must be verified independently of rotor width.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.wilwood.com\/Calipers\/CaliperProd?itemno=120-15735\"\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\u003eFor a modified brake system, provide its existing component specifications along with the vehicle details.
