GS Compact Integral Master Cylinder, 3/4 Inch Bore

Compact single-outlet master cylinder designed for space-limited brake system applications where precise pressure control and reliable operation are required. This GS series master cylinder features a rebuildable design with a high-pressure die-cast aluminum body and a durable black E-coat finish. The integral reservoir uses an internal bellows-style cap to maintain a positive seal and consistent fluid control.

A refined internal return spring and piston assembly provide smooth operation, positive pressure control, and quick, complete release, making this master cylinder well suited for manual brake systems in custom and performance applications.
