Its EPB system replaces cable actuation with dedicated electric parking calipers, so installation includes both hydraulic plumbing and electrical wiring. Wilwood Engineering’s disc brake systems and components serve motorsport, street-performance and specialized applications. Bill Wood founded the company in 1977; it is based in Camarillo, California. Wilwood designs and manufactures brake rotors and calipers as well as master cylinders, valves, brake lines and fittings. Selecting compatible components is essential to the complete system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-18044-D\u003c\/li\u003e\n\u003cli\u003eRotor specification: Spec-37 Iron, SRP Drilled \u0026amp; Slotted, vented; 12.88 x 1.10 inches\u003c\/li\u003e\n\u003cli\u003eCaliper specification: 4-piston Forged Narrow Superlite 4R in Black Powder Coat; radial mount\u003c\/li\u003e\n\u003cli\u003eIncluded service pad compound: BP-10; Stainless pistons\u003c\/li\u003e\n\u003cli\u003eCaliper body material: Forged aluminum\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eRotor\/hat wheel-stud clearance pattern(s): 5 x 5 in; 5 x 127 mm; match the installed hub\/axle pattern\u003c\/li\u003e\n\u003cli\u003eHousing\/flange application: 88-98 C1500\u003c\/li\u003e\n\u003cli\u003eRequired axle offset: 3.25 in; 82.55 mm\u003c\/li\u003e\n\u003cli\u003eParking equipment: separate electric calipers, controller and harness included\u003c\/li\u003e\n\u003cli\u003eHydraulic brake hoses: not included; select the correct application-specific lines\/fittings\u003c\/li\u003e\n\u003cli\u003eWheel clearance: 17-inch wheels may fit; verify the manufacturer’s complete caliper\/rotor template for the installed wheel\u003c\/li\u003e\n\u003cli\u003eSupplied as one kit with mounting hardware; spindles, hubs, master cylinder and booster are not included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eFor the listed Chevrolet and GMC C1500 pickups with the specified five-lug, two-wheel-drive configuration or Wilwood Iron ProSpindles.
