Suburban 4x4 parking brake pics?

[Scott Johnson]

I think I found all the parts to my e brake. I am not sure how everything hooks up, are there any springs to hold things together or does the tension from the rear cables hold everything in place? In the picture of the drivers side (first pic) what is the bracket that is behind the threaded rod? Does the rod go through or is that bracket for something else? Thanks for any help with this, Scott.
