{"product_id":"wilwood-120-13297","title":"Wilwood Right Aero4-ST Thermlock Caliper, Thick-Pad Configuration \/ 1.25-Inch Rotor Width","description":"\u003cp\u003eFour Thermlock pistons distinguish this right-hand AERO4\/ST configuration. The insulated 1.88\/1.62-inch differential bores are installed in a forged, Type III anodized body using type 6620 pads. Camarillo, California is home to Wilwood Engineering, the disc brake company Bill Wood founded in 1977. Its design and manufacturing range spans calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized brake systems.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-13297. Component: Aero4 Radial Mount caliper.\u003c\/li\u003e\n\u003cli\u003eSupply: one brake caliper, not a complete axle brake kit. Match the mating rotor, pads, bracket and connection hardware to the installation.\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT. Use a fitting with the correct thread and sealing seat.\u003c\/li\u003e\n\u003cli\u003eCaliper weight: approximately 7.1 lb.\u003c\/li\u003e\n\u003cli\u003eBore configuration 1.88\/1.62 inches across 4 pistons; piston material: Thermlock. Hydraulic effective area: 4.84 square inches.\u003c\/li\u003e\n\u003cli\u003ePiston dust boots: not fitted.\u003c\/li\u003e\n\u003cli\u003ePad fit is type 6620. Match the pad dimensions and compound to the rotor and intended braking conditions.\u003c\/li\u003e\n\u003cli\u003eConstruction and surface: forged aluminum housing finished in Type III anodize.\u003c\/li\u003e\n\u003cli\u003eNominal rotor width 1.25 inch; compatible outside diameter from 12.19 through 15.00 inches. Specified rotor-width limits: 1.10–1.28 inch.\u003c\/li\u003e\n\u003cli\u003eBracket interface: 7.09-inch radial centers with 0.45-inch holes. Specified mount height: 2.09 inches; orientation: right hand.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eConfirm that the existing brake design calls for this Thermlock piston and pad arrangement. A matching 7.09-inch radial bracket must align a nominally 1.25-inch-wide rotor and clear the wheel at the completed installation offset.\u003c\/p\u003e\u003cp\u003eAsk PMB Performance to check the complete brake arrangement before ordering. Our team brings over 20 years of experience; photographs and measured bracket and rotor dimensions make that check more useful.\u003c\/p\u003e","brand":"Wilwood","offers":[{"title":"Default Title","offer_id":67764019822770,"sku":"120-13297","price":744.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0521\/8792\/2610\/files\/120-13297-xl.jpg?v=1792508695","url":"https:\/\/pmbperformance.com\/products\/wilwood-120-13297","provider":"PMB Performance","version":"1.0","type":"link"}
