Abstract
A vehicle hydraulic brake system includes left and right manually operated brake pedals, and left and right hydraulic brake units. A pedal lock is movable to a locking position wherein the left and right brake pedals operate in unison. Left and right brake valves are operatively coupled to the corresponding brake pedal. A solenoid operated normally closed balance valve is connected between the left and right brake units. Optional left and right solenoid operated normally open blocking valves may be connected the corresponding brake valve and the corresponding brake unit. The blocking valves and the balance valve are controlled by an ECU as a function of sensed vehicle speed and brake pedal operation.
