{"product_id":"wilwood-120-17201","title":"Wilwood XRS4R Brake Caliper — Anodized, 1.10-Inch Nominal Rotor Width, 5.98-Inch Mount","description":"\u003cp\u003eThe rotor and bracket determine whether this anodized Wilwood XRS4R brake caliper is the correct choice. Its 1.10-inch rotor-width configuration works with the radial mount and 4-piston layout detailed below. Bill Wood established Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures calipers, rotors, master cylinders, valves, fittings and brake lines as part of its disc brake range. Its motorsport, street-performance and specialized products are chosen around the requirements of the whole braking system. The forged XRS4R is a four-piston radial caliper with an X-shaped center bridge and internal fluid passages. Its 10416 pad outline differs from the older Narrow Superlite pad shape. Match the radial bracket, rotor width and hydraulic bore before choosing this individual component.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-17201\u003c\/li\u003e\n\u003cli\u003eComponent: Forged XRS4R 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; Type III Anodize\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: 11.75–14.00 inches\u003c\/li\u003e\n\u003cli\u003eCaliper weight reference: 5.1 lb\u003c\/li\u003e\n\u003cli\u003ePistons: 4; stainless steel; bore dimensions 1.12\/1.12 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic piston area: 1.98 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eBrake pad shape: 10416; shape number does not specify a friction compound\u003c\/li\u003e\n\u003cli\u003eMounting interface: Radial; mounting centers 5.98 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole diameter: 0.39 inches\u003c\/li\u003e\n\u003cli\u003eMount height: 1.45 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 5.98-inch radial attachment to the existing bracket, then check caliper centering over the 1.10-inch nominal-width rotor.
