Wilwood GS Remote Compact Master Cylinders are a great solution for club racers, small open wheel racers, and other vehicles where there's limited mounting space for the master cylinder and fluid reservoir. Both fluid ports are located on the top of the cylinder body for additional end clearance in short mounting areas. A remote fluid reservoir can be put in a spot that simplifies bleeding processes and maintenance. A refined piston and spring assembly supply a quick and complete release, a result of positive pressure control. With a 1-1/4" stroke, these cylinders provide plenty of volume for a wide variety of custom applications.
