Abstract
The indicator comprises a loop of an electrical conductor 2 embedded in a body 1, from which a stud 3 and a lug 4 project. The stud 3 is pushed into a hole 9 made in a support plate 5 of the friction member, and the rest of the body and the lug 4 are turned down round one edge of the plate as a result of the deformability of the body between the stud 3 and the 4. The groove formed at the end of the stud 3 makes it possible to retain the lug 4 against the support plate in order to ensure that the indicator is fastened to this plate. The invention is used on disc brakes or drum brakes for motor vehicles.
