Not sure if you could find the individual part, probably will have to look into brake rebuild kits.

Well since the OP found his own answer, but didn't tell us what it was, for the rest of the class....

That's the self-adjuster cable. Or at least it WAS. It is supposed to have an eye on the other end and goes from the top anchor pin, around the crescent, and down to the top of the adjuster pawl.
