A brake shoe key is driven into operative engagement between a conventional brake shoe and a brake shoe support head in order to removably attach the brake shoe to the head. The brake shoe key is composed of cold workable austenitic stainless steel such that the key does not form stress cracks during fabrication and becomes stronger upon installation by driving.
