Abstract
A device for warning of the occurrence of excessive wear on the brake lining of a brake for a vehicle, in which a detecting element for detecting an increase in the amount of wear on the lining from a predetermined value is mounted on a rear plate supporting the lining, a part of the detecting element projects from the rear plate to the outside of the brake, and a metallic cylindrical cover is fixed to the rear plate so as to cover said projecting part of the detecting element, thereby preventing foreign material from contacting the detecting element when the vehicle is in operation.
