{"product_id":"wilwood-120-18061-bk","title":"Wilwood Black NDPR Radial Caliper with 2.46-Square-Inch Piston Area","description":"\u003cp\u003eThis black Narrow DynaPro is configured with four 1.25-inch stainless pistons and a thin, quarter-inch rotor opening. It supplies a 2.46-square-inch hydraulic piston area within the 4.75-inch radial mounting format. The correct choice depends on the complete brake design, including the master cylinder and the rotor’s friction-track position. 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: 120-18061-BK\u003c\/li\u003e\n\u003cli\u003eCaliper type: Narrow Dynapro Radial Mount\u003c\/li\u003e\n\u003cli\u003eConstruction: Billet Aluminium\u003c\/li\u003e\n\u003cli\u003eFinish: Black Powder Coat\u003c\/li\u003e\n\u003cli\u003ePiston bores: 1.25 \/ 1.25 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: 2.46 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 0.25 inch\u003c\/li\u003e\n\u003cli\u003eRotor thickness limits: 0.25–0.25 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter limits: 10.75–12.19 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: 4.75 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole size: 0.39 inch\u003c\/li\u003e\n\u003cli\u003eMount height: 1.61 inch\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: M10 x 1.25\u003c\/li\u003e\n\u003cli\u003eRequired pad shape: 7812\u003c\/li\u003e\n\u003cli\u003ePublished pad area: 6.36 square inches\u003c\/li\u003e\n\u003cli\u003ePublished pad volume: 2.1 cubic inches\u003c\/li\u003e\n\u003cli\u003eManufacturer-listed component weight: 3.2 lb\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eWhen servicing an existing package, compare the old caliper’s bore size before matching its color. The bracket must set the body at the specified mount height and center it laterally over the rotor. Check the pad thickness, fitting thread and wheel barrel separately; none is confirmed by radial spacing alone.\u003c\/p\u003e\u003cp\u003eFor help identifying the correct brake component, provide the caliper markings and installation dimensions.
