Abstract
A brake lining wear indicator is attached to a drum brake shoe backing plate adjacent the brake lining. The indicator provides a visual gage dimension that assists in the determination of when the brake linings should be replaced. This determination can be made in a very short period of time without requiring a physical measurement of the thickness of the brake lining on each brake shoe.
