New steel lines and really small bleeder

If block is bolted to chassis loosen / remove bolt and grab on it with vise grips / channel locks / etc and tighten some more. Unless you cross threaded it going in.

Bleeder screw. Yup. Deep socket. ( regular socket will usually fit. Unless it came from one of those Dollar Store sets)

Do it on the lawn. May leave small brown spot but it will grow back in the Spring.
