A medical device support system including a central shaft, an extension arm, a brake clamp assembly, and a brake actuator. The extension arm has a support for a medical device and a hub at its proximal end mounted to the central shaft for pivotable movement about the central shaft. The brake clamp assembly is secured in the hub for rotation therewith and includes first and second clamp portions. The brake actuator includes a cap, a plunger coupled to the cap for reciprocable axial movement relative to the cap, and a spring disposed between the cap and the plunger and configured to exert a biasing force against movement of the cap axially toward the plunger. The cap is adjustably mounted to the hub and coupled to the plunger to selectively urge the first and second clamp portions either toward or away from the central shaft to respectively increase or decrease a frictional braking force to the central shaft.
