Abstract: An attachment between segments (12) of a friction lining material and a brake shoe (11), in which the lining (12) is attached to the brake shoe (11) by a plurality of keying elements (16) attached by screws (17) to the brake shoe (11), and cooperating with a plurality of associated grooves (18) in the lining (12) in such a manner as to prevent the lining (12) from becoming detached from the brake shoe (11). The keying elements (16) being retained within their associated grooves (18) whereby there will be no, or a limited amount of, relative movement between the lining (12) and the brake shoe (11) in any direction.
