Abstract: A combination brake and anti-lock system for a wheeled vehicle such as an aircraft includes an operator controlled source of pressurized hydraulic fluid for selectively applying hydraulic pressure to a hydraulically actuated wheel rotation braking device which responds to the applied hydraulic pressure to apply a braking force to a wheel of the vehicle to thereby arresting wheel motion. There is a low pressure hydraulic fluid return with a normally open hold valve in circuit between the source and the braking device for selectively opening and closing a fluid flow path from the source to the braking device and a normally closed decay valve in circuit between the braking device and the return for selectively opening and closing a fluid flow path from the braking device to the return.
