Abstract
A brake condition monitoring system includes a central control receiving signals from each of the several brake actuators mounted on a vehicle. The control receives all of the signals, and sends a single signal to a display in the cab of the vehicle indicative of which of the brake actuators may be evidencing a malfunction. The signals from each brake actuators are unique such that the control can determine which brake actuator each signal is from. The control is also capable of monitoring conditions other than movement of a push rod. The control can ensure that each of the parking brakes have been fully released, the system can monitor the number of actuations for each of the brake actuators, the system can monitor whether a particular brake has been actuated for a long period of time and the system can act as a self check for each of the sensors associated with the brake actuators by monitoring which brake actuators are actuated to ensure that each of the brake actuators sends a signal indicative of an actuation. The invention further anticipates other conditions may be controlled or sensed. In further aspects of this invention, magnets associated with the push rod are mounted wi…
