Product Description

The Wilwood 260-15091 GS Compact Remote Master Cylinder is a versatile master cylinder designed for custom brake or clutch systems where space is limited but effective hydraulic pressure and fluid volume control are required. The .78" bore provides a balanced combination of pressure and displacement for many performance and street applications. Its compact, remote design enables flexible placement in tight engine bays, race cars, hot rods, and custom chassis builds.

Constructed from a robust high-pressure die-cast aluminum body with a corrosion-resistant black e-coat finish, the 260-15091 features a refined internal piston and return spring assembly that promotes responsive fluid control and positive release. With its standard 7/16-20 inlet and 3/8-24 IF outlet ports, this master cylinder integrates easily with commonly used brake and clutch line fittings. Because this is a universal component rather than vehicle-specific, fitment depends on your system design, mounting configuration, and space constraints rather than published year/make/model listings.
