{"product_id":"wilwood-120-15796-bk","title":"Wilwood D154-DS Brake Caliper, Black, 1.04-Inch Rotor Width","description":"\u003cp\u003eThe black Wilwood D154-DS is an individual brake caliper. It combines a 5.46-inch attachment span with 2.50-inch piston bore; confirm the rotor centerline and 1.04-inch width configuration before installation. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. Its disc brake design and manufacturing work includes master cylinders, valves, fittings and brake lines as well as rotors and calipers. The company serves motorsport, street-performance and specialized applications in which the entire brake system determines component choice. This D154-DS floating caliper uses a single 2.50-inch stainless piston with a dust wiper seal and D154-shape pads. It replaces the matching GM metric brake arrangement only after the slider, rotor and hose connection have been checked. It is not an axle kit.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-15796-BK\u003c\/li\u003e\n\u003cli\u003eComponent: D154-Dust Seal Single Piston Floater; one individual caliper\u003c\/li\u003e\n\u003cli\u003ePlacement: Universal mounting orientation; verify axle position\u003c\/li\u003e\n\u003cli\u003eConstruction and finish: Forged aluminum; Black Powder Coat\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 1.04 inches\u003c\/li\u003e\n\u003cli\u003eRotor width range: 0.87–1.04 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter range: 11.00–12.19 inches\u003c\/li\u003e\n\u003cli\u003eCaliper weight reference: 4.7 lb\u003c\/li\u003e\n\u003cli\u003ePistons: 1; stainless steel; bore dimensions 2.50 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic piston area: 4.90 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: Yes\u003c\/li\u003e\n\u003cli\u003eBrake pad shape: D154; shape number does not specify a friction compound\u003c\/li\u003e\n\u003cli\u003eMounting interface: Floating; mounting centers 5.46 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole diameter: 0.69 inches\u003c\/li\u003e\n\u003cli\u003eMount height: 0.37 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: M10 x 1.50\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eThis caliper requires the measured 1.04-inch rotor-width configuration and the matching floating bracket on 5.46-inch centers.
