Abstract
A brake wear indicator to provide visual and tactile indication of unacceptable brake wear. The brake wear indicator has a hub drive attached to a cam shaft, a brake wear disk attached to the hub drive and a body attached to a slack adjuster lever. The brake wear disk has a wear detector lug. The body has two the travel limit lugs which extend towards the centerline of the brake wear disk and are on the end of flexible fingers. When the brake linings are approaching unacceptable wear, the wear detector lug contacts one of the travel limit lugs and pushes the travel limit lug and the end of the corresponding finger away from the adjacent outer surface of the body. The rising of the end of the finger above the adjacent surface provides visual and tactile indication of unacceptable brake wear.
