Wear indicator for a friction member of an automotive brake
First Claim
1. A wear indicator for a friction member of an automotive brake, designed to be mounted on the friction member so that an electrical conductor member forming part of the indicator is rubbed against by a rotating member forming part of the brake when the friction member reaches a thickness less than a predetermined value due to wear of the friction member by the rotating member, the conductor member passing tangentially in a plane of maximum permissible wear of the friction member, said conductor member comprising an electric coaxial cable having a conducting core and a conducting sleeve insulated one from the other by an insulating coating and connected by a conducting socket, the conducting socket connecting bared ends of said core and sleeve.

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.
