Abstract

The arrangement indicates pad wear for brake shoes comprising a contact head embedded in the brake shoe and a socket connector adapted to be readily connected with the contact head with an electrical line leading from the socket connector to an indicating arrangement. When the worn brake shoe is to be replaced only the contact head which is embedded in the brake shoe is discarded. The socket connector can be reused after each replacement.
