Brake wear managing system
First Claim
1. A brake wear managing system for a vehicle provided with at least one drum brake assembly including a push rod and an air drum bolt, said brake wear managing system comprising:
- at least one sensor assembly including a sensor and a mounting assembly to mount said sensor to one of the at least one drum brake assembly for movement in unison with the push rod;
said mounting assembly including a universal joint connecting said sensor assembly to said air drum bolt of said drum brake assembly;
the sensor being so configured as to generate a signal responsive to brake wear; and
an on-board controller coupled to each sensor;
said on-board controller being configured to receive said signal from each sensor and to generate brake wear condition signals accordingly.

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.
