Abstract
A brake, system, and method are presented. The brake includes friction material, a backing pad, sensor-wear material embedded within the friction material, and an electronics assembly. The electronics assembly is configured to measure a characteristic of the sensor-wear material, such as the electrical resistance or the temperature of the sensor-wear material. The sensor-wear material may be applied to the brake using a variety of approaches. A condition of the brake, such as a brake-wear value or an estimated-mileage value is determined, based on the measured characteristic of the sensor-wear material. A brake-wear state may be determined by comparing the brake-wear value to one or more thresholds. The brake-wear value, estimated-mileage value, and/or the brake wear state may be indicated on a brake-wear indicator.
