A brake and anti-skid control utilizing optical input sensors for determining wheel speed or position and suitable for aircraft use is disclosed. A valve control has a continuous source of pressurized hydraulic fluid, a hydraulically actuated wheel rotation brake device which responds to applied hydraulic pressure to apply a braking force to the wheel to arrest wheel rotation, a low pressure hydraulic fluid return, and a flow control servo valve interconnecting the source, the return, and the braking device for directing fluid from the source to the braking device when in a first state and for directing fluid from the braking device to the return when in a second state. Applied hydraulic pressure is monitored and if that monitored pressure exceeds a command pressure, further fluid from the braking device is diverted to the return.
