{"product_id":"wilwood-120-16686-y","title":"Wilwood Yellow Narrow DynaPro-P Caliper — 4.75-Inch Mount and 0.81-Inch Rotor Width","description":"\u003cp\u003eWilwood Narrow DynaPro-P calipers must be matched by width and mounting configuration. This yellow brake caliper has 1.12\/1.12-inch bore dimensions, a 4.75-inch mounting span and the 0.81-inch-wide rotor specification. Founded by Bill Wood in 1977, Wilwood Engineering is based in Camarillo, California. It designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications. Components must be selected to suit the complete brake system. Narrow DynaPro-P uses four 1.12-inch stainless pistons and the 4812 pad outline. The compact radial mount is suited to a measured bracket arrangement. Check rotor diameter and pad sweep against the installation drawing.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-16686-Y\u003c\/li\u003e\n\u003cli\u003eComponent: Narrow Dynapro-P 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: Billet aluminum; Yellow Powder Coat\u003c\/li\u003e\n\u003cli\u003ePistons: 4; stainless steel; bore dimensions 1.12\/1.12 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic piston area: 1.98 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eBrake pad shape: 4812; shape number does not specify a friction compound\u003c\/li\u003e\n\u003cli\u003eMounting interface: Radial; mounting centers 4.75 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole diameter: 0.39 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 0.81 inches\u003c\/li\u003e\n\u003cli\u003eRotor width range: 0.75–0.86 inches\u003c\/li\u003e\n\u003cli\u003eCaliper weight reference: 3.8 lb\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eVerify the radial mounting interface and the complete rotor-width range shown above. Axle placement is determined by the engineered brake package, not by a generic caliper designation. Account for the 1.12\/1.12-inch bores when selecting the master cylinder and front-to-rear balance. Check that the 1\/8-27 NPT fitting, flexline and wheel remain clear throughout their operating movement.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.wilwood.com\/Calipers\/CaliperProd?itemno=120-16686-Y\"\u003eWilwood caliper specifications\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003eA correct caliper choice begins with the complete brake arrangement.
