Abstract
The wear indicator comprises essentially a coaxial cable (4, 5) of which the conducting core (4) and the conducting sleeve (5) are connected electrically by a socket (6, 6', 6", 6'41 ). One bared end of the core (4) is disposed on a wear limit plane of a lining forming part of a friction member. A rotating member, disc or drum then cuts the end of the core when the lining reaches its permissible wear limit.
