PROBLEM TO BE SOLVED: To facilitate adjustment of rotary brake control.SOLUTION: A rotary brake control system for a work machine comprises: a neutral free rotary hydraulic circuit; a rotary brake which applies braking force to a rotary body; and a braking force adjustment device which adjusts braking force of the rotary brake. The braking force adjustment device comprises: a braking operation device that an operator operates to generate braking force at the rotary brake; a braking operation manipulated variable detection device which detects a manipulated variable of the braking operation device; a changing operation member by which the operator changes relation between the detected manipulated variable of the braking operation device and the braking force; a changed manipulated variable detection device which detects a manipulated variable of the changing operation member; and a driving command output device which outputs a drive command to the rotary brake based upon the detected manipulated variable of the braking operation device and the detected manipulated variable of the changing operation member.SELECTED DRAWING: Figure 2
