Wilwood 7/8-inch Combination Remote Master Cylinder Rebuild Kit with Spring and Boot

The seven-eighths-inch bore version of this rebuild package renews the matching Combination Remote master's piston and seals. Its spring, boot, retaining ring and O-rings support service of the original cylinder rather than changing its displacement or mounting layout. 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.
