Abstract
The wear indicator of the friction lining (10) of a brake consists essentially of a loop of conductive wire arranged in a sleeve (18) closed by way of an insulating bush (20) of cylindrical form and having a longitudinal axis (16). The loop is in contact at least once with substantially all the generatrices of the inner wall of the bush (20). Preferrably, the loop consists of a substantially straight first part (24) arranged parallel to the longitudinal axis (16) and a second part (26) wound helically round the first part (24) and connected to the latter.
