Abstract
A disc brake pad having an integral backing plate on its rear surface is provided with a removable wear indicator. An insertion hole for the indicator extends through the backing plate and into the pad for a distance equal to the length of the wear indicator. To prevent the wear indicator from being forced backward out of the hole during operation of the brake, a thin plate is placed over the backing plate and firmly clamped thereto, thereby blocking rearward movement of the indicator.
