Abstract
The present invention relates to a friction member comprising a support plate (26, 30) and a friction element (22, 24) arranged on one side of the support plate 26, 30), the friction element (22, 24) being adapted to engage one face of a rotating member (12), and at least one wear indicator (32) associated with the support plate (26, 30) so as to generate an audible signal when the friction element (22, 24) possesses, on account of its wear, a predetermined thickness (L). According to the invention, the wear indicator (32) is formed by a spring comprising an intermediate part (34) for fixing of the wear indicator (32) onto the support plate (26, 30) on the side of the latter which bears the friction element (22, 24), a first end part (36) for emission of the audible signal and a second end part (40, 50, 36') for locking of the wear indicator (32) in rotation with respect to the support plate (26, 30).
