Wilwood 1-1/16-inch Chrysler-Style Tandem Master Kit with Pushrod, Retainer and Boot

The pushrod, retainer and dust boot are included with this Chrysler-style tandem master package. Its aluminum body and plastic reservoir provide the same one-and-one-sixteenth-inch hydraulic bore as the master-only version, with added manual-actuation hardware. Wilwood Engineering designs disc brake systems and manufactures a range of calipers, master cylinders, valves, fittings, rotors and brake lines. Founded in 1977 by Bill Wood, the Camarillo, California company serves specialized, street-performance and motorsport applications. Component selection requires understanding the brake assembly as a whole, including its hydraulic sizing and mechanical interfaces.
