Product details
With a 1-1/8-inch bore, this black E-coated tandem master prioritizes the displacement needs of an assisted brake system. The body includes two fluid chambers and dual-side outlet choices, while the operating pushrod is selected separately. Camarillo, California is home to Wilwood Engineering, founded in 1977 by Bill Wood. Its disc brake design and manufacturing range includes valves, master cylinders, calipers, brake lines, rotors and fittings for street-performance, specialized and motorsport use. These parts are selected together so the completed braking system has the required hydraulic and mechanical arrangement.

Fitment & Compatibility
This size is primarily for power brakes; confirm the vacuum or hydraulic assist arrangement instead of choosing by mounting pattern alone. Provide clearance for the reservoir lid and allow the full 1.10-inch piston stroke without linkage preload.
