I have transferd most parts from old deck to new deck for a John Deere L110, but forgotten how to put the brake arm pully back on hence am after an over view pic so I can put it back togethier asap correctly.

Go to this link for an exploded view.
Copy and paste:
http://jdpc.deere.com/jdpc/servlet/com.deere.u90490.partscatalog.view.servlets.HomePa geServlet
If that link doesn't work then type in jdpc.deere.com and go from there.
