{"product_id":"wilwood-120-18192","title":"Wilwood Right Aero4-ST Anodized Radial Brake Caliper, 1.62\/1.38-Inch Pistons","description":"\u003cp\u003eThe right-hand Aero4-ST is a forged four-piston caliper with a 1.62\/1.38-inch staggered bore arrangement and Thermlock insulated-piston construction. Its radial mounting format and larger rotor envelope suit brake assemblies designed around this Aero4 body. Type III anodizing finishes the housing, and the caliper’s mounting and piston-area specifications define the matched replacement. 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: 120-18192\u003c\/li\u003e\n\u003cli\u003eCaliper type: Aero4 Radial Mount\u003c\/li\u003e\n\u003cli\u003eConstruction: Forged Aluminium\u003c\/li\u003e\n\u003cli\u003eFinish: Type III Anodize\u003c\/li\u003e\n\u003cli\u003ePiston bores: 1.62 \/ 1.38 inches\u003c\/li\u003e\n\u003cli\u003ePiston type: Thermlock\u003c\/li\u003e\n\u003cli\u003ePiston count: 4\u003c\/li\u003e\n\u003cli\u003ePublished piston area: 3.56 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 1.25 inch\u003c\/li\u003e\n\u003cli\u003eRotor thickness limits: 1.10–1.28 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter limits: 12.19–15.00 inches\u003c\/li\u003e\n\u003cli\u003eMounting style: Radial\u003c\/li\u003e\n\u003cli\u003eMounting side: Right Hand\u003c\/li\u003e\n\u003cli\u003eMounting centers: 7.09 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole size: 0.45 inch\u003c\/li\u003e\n\u003cli\u003eMount height: 2.09 inch\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eRequired pad shape: 6617\u003c\/li\u003e\n\u003cli\u003ePublished pad area: 11.1 square inches\u003c\/li\u003e\n\u003cli\u003ePublished pad volume: 5.2 cubic inches\u003c\/li\u003e\n\u003cli\u003eManufacturer-listed component weight: 7.1 lb\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eMatch the right-hand body to the brake package’s intended rotation and bleed orientation.
