A combined steering clutch and brake control system for track-type vehicles. The system includes a pair of hydraulic booster valves modified for cooperation with flow control valve means for controlling fluid flow to the vehicle steering components. The booster valves and flow control means are arranged within the system for combined sequential control of the clutching and braking functions of each track of the vehicle by selective operation of a control lever associated with each booster valve. The control system permits an independent braking function by simultaneous operation of the control levers to apply the braking mechanism of both tracks.
