Product details
This compact aluminum master stores its fluid in an integral 1.4-ounce reservoir rather than a separate container. Wilwood specifies it for clutch actuation and smaller hydraulic master-cylinder requirements, with a three-quarter-inch bore and a 1.40-inch stroke. Bill Wood established Wilwood Engineering in 1977. From Camarillo, California, Wilwood designs and manufactures disc brake systems and a component range covering master cylinders, rotors, calipers, fittings, valves and brake lines. Across its motorsport, specialized and street-performance applications, the correct choice depends on the complete brake system rather than one dimension alone.

Fitment & Compatibility
Match the slave cylinder or brake circuit's volume demand to the bore and small reservoir capacity. The mounting centers are 2.25 inches, the pushrod is threaded 5/16-24 and the outlet uses a 3/8-24 female inverted-flare seat. Application depends on the complete hydraulic arrangement, not a vehicle badge.
