Product Description

The Wilwood 260-15096 GS Compact Integral Master Cylinder is a universal hydraulic control component designed for custom brake or clutch system applications where space is limited but performance and reliability are still required. Its 5/8" bore and compact design deliver balanced fluid pressure and displacement, making it well-suited for lightweight street cars, race cars, hot rods, and custom builds. The integral reservoir design features a positive-seal bellows cap to help maintain fluid integrity, and the refined internal spring and piston assembly provide positive pressure control with every actuation.

Constructed from high-pressure die-cast aluminum with a protective black E-coat finish, this master cylinder integrates easily with common brake or clutch line fittings via its single 3/8-24 inverted flare outlet port. The rebuildable design allows periodic servicing with compatible rebuild kits, extending component life. Because this part is universal and not tied to specific vehicle year/make/model fitments, compatibility depends on your hydraulic system layout and mounting requirements.
