Product Description

The Wilwood 260-15090 GS Compact Remote Master Cylinder is a versatile hydraulic component engineered for performance braking or clutch systems where space is limited. Its .70" bore size delivers balanced fluid pressure and volume suitable for a range of custom brake or clutch applications. The compact design, paired with a remote reservoir setup, lets you install the master cylinder in tight engine bay or chassis locations without compromising hydraulic performance.

Constructed from a durable high-pressure die-cast aluminum body with a protective e-coat finish, this rebuildable master cylinder features a refined piston and return spring assembly that ensures positive pressure control and quick release. The standard 7/16-20 threaded inlet and 3/8-24 IF outlet provide compatibility with common brake and clutch line fittings used in custom builds and performance upgrades. Because it is a universal component rather than vehicle-specific, fitment depends on your brake or clutch system layout and mounting requirements rather than specific vehicle year/make/model listings.
