Its forged radial-mount body is specified for the 6617 pad shape and a nominally 1.25-inch-wide rotor. 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: 120-13285-BK. 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\u003eNominal rotor width 1.25 inch; compatible outside diameter from 12.19 through 15.00 inches.

Mount centers remain 7.09 inches, but rotor offset, pad depth and wheel clearance require their own checks.\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":67764018544818,"sku":"120-13285-BK","price":595.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0521\/8792\/2610\/files\/Aero4_Radial_Mount-xl_dd610f77-5486-479e-8407-c00c5cdfe697.jpg?v=1792508672","url":"https:\/\/pmbperformance.com\/products\/wilwood-120-13285-bk","provider":"PMB Performance","version":"1.0","type":"link"}
