A brake shoe without a metal backing has a metal insert comprising two spaced apart bodies, a connecting portion having a back face adjacent to the back surface of the brake shoe, and two generally parallel radially extending flanges integral with the connecting portion. The parallel extensions define a keyway, wherein when the brake shoe is emplaced on the brake head, the keyway extends through an opening provided in the brake head.
