Abstract
A vehicle hand control brake valve includes a piston, positioned based on an engagement of a vehicle parking brake, a service brake actuation valve, and a control mechanism. The control mechanism mechanically interacts with the service brake actuation valve to set a position of the service brake actuation valve. A level of actuation of vehicle service brakes is set based on the position of the service brake actuation valve. The service brake actuation valve is set to a position to actuate the service brakes when the control mechanism is set to a latch position. The control mechanism only is latched in the latch position when the vehicle parking brake is engaged.
