A wear monitoring apparatus for a disc brake, particularly a sliding caliper disc brake, is described. The disc brake has a sliding thrust piece which receives an application force exerted by an application mechanism, and a longitudinally adjustable transmission mechanism for transmitting the application force from the sliding thrust piece to a brake pad. Longitudinal adjustment of the transmission mechanism is a function of the extent of frictional wear of the brake pad. The wear monitoring apparatus includes a sensor for monitoring the mutual relative excursion of two elements which excursion is attributable to frictional wear of the brake pad. The sensor is mounted on the sliding thrust piece and/or the transmission mechanism and determines relative excursion between the sliding thrust piece and the transmission mechanism.
In a disc brake having a sliding thrust piece, an application mechanism for applying an application force to the thrust piece, and a longitudinally adjustable transmission means for transmitting the application force from the sliding thrust piece to a brake pad in a manner compensating for frictional wear of the brake pad by longitudinal adjustment of said transmission means, the improvement comprising wear monitoring means connected on one of the sliding thrust piece and the transmission means for determining relative excursion between said sliding thrust piece and said transmission means, which excursion is attributable to frictional wear of the brake pad.
