66 Valiant, rear brake questions

You need to fix these issues for the brakes to work right... Please don't drive it until you get it fixed properly, it can be dangerous that way...

Agreed, I'm going to do it right before driving it.

Oh, and as if I'm not having enough financial fun, the really good looking tires I bought on the aftermarket wheels turned out to be over TWENTY years old. Holy Crap, Batman! I will be getting new skins before taking this on the road again. Good tires and brakes are non-negotiable in my book.
