{"product_id":"wilwood-120-15598-rd","title":"Wilwood Aero4-DS Brake Caliper — Red, 7.09-Inch Radial Mount","description":"\u003cp\u003eWilwood Aero4-DS calipers must be matched by width and mounting configuration. This red brake caliper has 1.38\/1.38-inch bore dimensions, a 7.09-inch mounting span and the 1.10-inch-wide rotor specification. The Aero4-DS combines four hydraulic pistons with dust wiper seals. Its radial attachment must be aligned to the rotor centerline with the correct bracket; the caliper alone does not establish a wheel or vehicle fit. 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.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-15598-RD\u003c\/li\u003e\n\u003cli\u003eComponent: Aero4-DS Radial Mount; 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; Red Powder Coat\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 1.10 inches\u003c\/li\u003e\n\u003cli\u003eRotor width range: 1.00–1.10 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter range: 12.19–15.00 inches\u003c\/li\u003e\n\u003cli\u003eCaliper weight reference: 6.9 lb\u003c\/li\u003e\n\u003cli\u003ePistons: 4; stainless steel; bore dimensions 1.38\/1.38 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic piston area: 3.00 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: Yes\u003c\/li\u003e\n\u003cli\u003eBrake pad shape: 6617; shape number does not specify a friction compound\u003c\/li\u003e\n\u003cli\u003eMounting interface: Radial; mounting centers 7.09 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole diameter: 0.45 inches\u003c\/li\u003e\n\u003cli\u003eMount height: 2.09 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eMatch the 7.09-inch radial attachment to the existing bracket, then check caliper centering over the 1.10-inch nominal-width rotor.
