<p>The lining consists of one or more friction blocks (11) with a retaining collar at its base to engage between two plates (13A,13B) forming a support (13). The upper plate (13A) has an aperture (14) in it of smaller dimensions than the retaining collar, while the lower one (13B) locks the block (11) in place, having at least one tongue which projects from the plate and engages with a hole (16) in the base of the block, situated eccentrically in relation to its axis. The tongue (15) is formed by cutting and bending a section of the lower plate and is thus made in one piece with it; the upper plate is flat, and the block's retaining collar (12) is circular in shape and of constant thickness, being made in one piece with the block.</p> |
