i call it dumb. Probably a shade tree expert that should have stuck to trees. How hard would it have been to look it up or ask someone that would know? If there is no brain function behind the wrench you end up with stuff like this.
Yes, the emergency brake rod was vibrating against the body right at the inside leading edge of the wheel well. (and the anti rattlers were installed backwards too...about 2 inches from rod bump)
Also, the return spring on the emergency brake lever was pretty much non-functional which led to the lower brake shoe drag and wear out.
