Wilwood 0.70-inch Compact Remote Master Cylinder, Bare Aluminum, Single Flare Outlet

A seven-tenths-inch bore gives this bare aluminum remote master a specified 0.53-cubic-inch output. Its detached fluid supply suits a custom layout where the cylinder and reservoir cannot share the same space, including appropriate small-caliper and clutch systems. Master cylinders are part of Wilwood Engineering's wider disc brake range, alongside calipers, rotors, valves, fittings and brake lines. Wilwood was founded in 1977 by Bill Wood and designs and manufactures its systems from Camarillo, California for motorsport, specialized and street-performance applications. Hydraulic sizing and mechanical compatibility remain decisions for the complete brake system.

Fitment & Compatibility

Choose the separate reservoir and 7/16-20 feed fitting for the installed arrangement. The pressure connection is 3/8-24 female inverted flare, and the threaded rod must move freely through the complete stroke. Check the two-and-one-quarter-inch flange spacing and actual circuit requirements rather than assuming a vehicle application.
