{"product_id":"wilwood-120-18086","title":"Wilwood Anodized NDPR Thin-Pad Brake Caliper, Piston Specification Requires Confirmation","description":"\u003cp\u003eThis Type III anodized Narrow DynaPro is a four-piston radial brake caliper for a nominal 0.25-inch rotor width. Its 4.75-inch mounting centers and M10 x 1.25 inlet are documented, but the published bore entries do not agree with the listed piston area. The piston configuration therefore needs confirmation before this part is selected for hydraulic sizing. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized uses, including calipers, brake rotors, master cylinders, valves, fittings and brake lines; each component must match the requirements of the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-18086\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: Type III Anodize\u003c\/li\u003e\n\u003cli\u003ePiston configuration: Four pistons; published bore and piston-area information require confirmation before selection\u003c\/li\u003e\n\u003cli\u003ePiston type: Stainless\u003c\/li\u003e\n\u003cli\u003ePiston count: 4\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: 4.1 lb\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eSupply the caliper reference and existing brake-package information when checking fitment.
