Abstract: A brake wear managing system is disclosed herein. The brake wear managing system comprises a plurality of sensor assemblies, an on-board controller and, optionally, a remote controller. The sensor assembly includes a mounting assembly and a sensor to measure the wear of a brake assembly and to generate a signal accordingly. Each sensor is coupled to the on-board controller. The on-board controller is configured to generate brake wear condition signals in response to the signal generated by each sensor. The optional remote controller is directly connected to the on-board controller or coupled to it via a wireless communication signal. The remote controller is configured to be operated either in maintenance mode or in operational mode.
