Component: D154 Single \u0026amp; Dual Piston Floater 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\u003ePiston dust boots: not fitted.\u003c\/li\u003e\n\u003cli\u003eCaliper weight: approximately 4.6 lb.\u003c\/li\u003e\n\u003cli\u003eNominal rotor width 0.81 inch; compatible outside diameter from 11.00 through 12.19 inches. Specified rotor-width limits: 0.70–0.81 inch.\u003c\/li\u003e\n\u003cli\u003eConstruction and surface: forged aluminum housing finished in Red powder coat.\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: M10 x 1.50. Use a fitting with the correct thread and sealing seat.\u003c\/li\u003e\n\u003cli\u003eBore configuration 1.12 inches across 2 pistons; piston material: stainless steel. Hydraulic effective area: 1.98 square inches.\u003c\/li\u003e\n\u003cli\u003eBracket interface: 5.46-inch floating centers with 0.69-inch holes. Specified mount height: 0.37 inches; orientation: universal.\u003c\/li\u003e\n\u003cli\u003ePad fit is type D154.

The bracket, pad sweep and metric inlet must match the actual rotor arrangement rather than another red D154 with larger bores.\u003c\/p\u003e\u003cp\u003eWith 20+ years of experience, PMB Performance can help compare the actual brake hardware. Supply the caliper number, rotor dimensions and mounting measurements when asking about compatibility.\u003c\/p\u003e","brand":"Wilwood","offers":[{"title":"Default Title","offer_id":67764014350514,"sku":"120-11875-RD","price":222.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0521\/8792\/2610\/files\/120-11875-RD-xl.jpg?v=1792508627","url":"https:\/\/pmbperformance.com\/products\/wilwood-120-11875-rd","provider":"PMB Performance","version":"1.0","type":"link"}
