Abstract
A hydraulic system for a vehicle in which the first and second brake valves are arranged in a parallel configuration. The pressure inlet of the first and second brake valves are connected to a source of hydraulic fluid and the exhaust outlets of the first and second brake valves are connected to the first and second brakes, respectively. The control inlets of the first and second brake valves are directly responsive to a braking signal from an operator of the vehicle. First and second control valves are configured to selectively provide hydraulic fluid to the control inlet of the first and second brake valves, respectively.
