Abstract
An electrical contact is embedded in an insulator which, in turn, is fitted onto the disk side of the backing plate on a disk pad. When the pad wears excessively the insulator is worn away and the contact abuts the disk so that an alarm signal may be generated. Further wear will cause the disk to abrade and break the contact. The contact assembly is compact and enters the brake assembly through a vent hole which is typically provided therein.
