{"product_id":"wilwood-120-16686-bk","title":"Wilwood Narrow DynaPro-P Brake Caliper, Black, 0.81-Inch Rotor Width","description":"\u003cp\u003eThis black Wilwood Narrow DynaPro-P brake caliper uses a 4.75-inch radial mount and the 0.81-inch rotor-width configuration. It is sold as one caliper, with its piston and mounting specification selected for the complete brake assembly. Wilwood Engineering, founded in 1977 by Bill Wood, is based in Camarillo, California. The company designs and manufactures disc braking equipment for motorsport, street-performance and specialized use. Calipers, rotors, master cylinders, valves, fittings and brake lines form a range whose individual components must be matched to one another. 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-BK\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; Black 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\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\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\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eChoose this component around the existing rotor and bracket, including the 0.81-inch nominal rotor width and 4.75-inch mounting span. Axle placement is determined by the engineered brake package, not by a generic caliper designation. Compare pad support, caliper offset and piston volume with the brake being replaced. Wheel size alone cannot confirm spoke or barrel clearance.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.wilwood.com\/Calipers\/CaliperProd?itemno=120-16686-BK\"\u003eWilwood caliper specifications\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003eShare the vehicle and the brake system actually installed with PMB Performance before ordering if the configuration is uncertain.
