Abstract:
A brake shoe without a metal backing has a metal insert (9) comprising a main body (10), two wing-like extensions (12/13) integral with, on opposite sides of and extending away from the main body having back faces adjacent to the back surface of the brake shoe, two generally parallel radially extending flanges (15/16) integral with the main body and/or the wing-like extensions. The parallel extension defines a keyway (17), wherein when the brake shoe is emplaced on the brake head, the keyway extends through an opening provided in the brake head.
