Abstract
A brake monitoring system generally includes a plurality of brake monitors mounted on each of a plurality of brake actuators. Each brake monitor generally comprises a sleeve mounted to a push rod which moves relative to a stone shield on the brake actuator. The displacement of the sleeve relative to the stone shield is measured to determine the stroke of the brake actuator. This information is sent via an RF transmitter to a controller which determines the condition of each of the brakes.
