A controller and wiring harness are included for the EPB installation alongside the four-piston service brakes. Founded in 1977 by Bill Wood and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and components for motorsport, street-performance and specialized applications. Its range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to work together within a properly matched brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-18161\u003c\/li\u003e\n\u003cli\u003eService calipers: Forged Narrow Superlite 4R; 4 pistons; radial mount; Black Powder Coat\u003c\/li\u003e\n\u003cli\u003eBrake rotors: 12.88 x 1.10 inches; Spec-37 Iron; GT Slotted; vented construction\u003c\/li\u003e\n\u003cli\u003ePads: BP-10; piston material: Stainless\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): 6 x 5.5 in; 6 x 139.7 mm; match the installed hub\/axle pattern\u003c\/li\u003e\n\u003cli\u003eHousing\/flange application: K5 Blazer \/ K10\u003c\/li\u003e\n\u003cli\u003eRequired axle offset: 2.46 in; 62.48 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\u003eThe Superlite\/EPB installation is for a measured 2.46-inch-offset GM six-lug rear axle using the documented flange.
