Abstract
A brake apparatus having a friction pad riveted to a brake shoe and a light conductor extending through the pad within its working thickness. As the pad is worn away, the light conductor is severed by the abrasive action of a rotatable member causing a remote indicator, responsive to the interruption of light transmission through the conduit, to signal the need to replace the pad. The configuration of the light conduit insures that the signal will be given at the appropriate time despite misalignment between the pad and the rotatable member.
