1. An apparatus for processing a plurality of brake wear signals from a corresponding plurality of brake wear sensors of a vehicle brake system, the apparatus comprising:
an interfacing device, including a multiplexer having at least a number of multiplexer input ports corresponding to a number of the brake wear sensors of the vehicle brake system, arranged to receive the plurality of brake wear signals corresponding to the plurality of brake wear sensors of the vehicle brake system;
a controller arranged to control the interfacing device to provide a location signal indicative of which one of the plurality of brake wear sensors is providing a brake wear signal indicative of a worn brake, the interfacing device including a sample-and-hold circuit that cooperates with the multiplexer to sample each brake wear signal of the plurality of brake wear sensors and to maintain each sampled brake wear signal for a sufficient amount of time so that the controller can process the sampled brake wear signal.
