Claim 15:
16. A braking control system for a work machine, comprising:
a controller;
a brake actuator for engaging or disengaging a brake; and
an electrohydraulic valve system comprising:
a valve body including a port disposed in fluid communication with the brake actuator;
a valve spool disposed within the valve body and in fluid communication with the port, the valve spool including at least a first land and a second land;
an armature positioned with respect to the valve spool to move the valve spool axially within the valve body between a first position and a second position;
a spring disposed within the valve body and biasing the valve spool to its first position;
a first electromagnetic coil and a second electromagnetic coil arranged relative to one another and the armature for forming a magnetic field when energized; and
a detent system positioned within the valve body, the detent system configured to exert an axial force to the valve spool or armature;
wherein, the first electromagnetic coil is in electrical communication with the controller via a first communication link, and the second electromagnetic coil is in electrical communication with the controller via a second communication link;
further wherein, the first communication link and the second communication link are independent from one another.
