Patent attributes
A park brake system for adjusting a tension in a brake cable that is coupled to a park brake. The park brake system can include a driver that is communicatively coupled to a microcontroller, and an actuator that is rotatably displaceable by operation of the driver. An equalizer assembly can be linearly displaced along the rotating actuator to adjust a tension in the brake cable. The microcontroller can monitor a current being drawn by the driver as the driver is operated, and generate instructions to cease operation of the driver upon the current reaching a predetermined current threshold that corresponds a maximum force that is to be applied by the park brake. The microcontroller can also, when the park brake is being released from a set position, count pulses outputted by an encoder in connection with determining whether the park brake has reached a running clearance position.
