There are no lines there mate, unless you are thinking of the attessa , that needs bleeding if you want to change the fluid there .
Get yourself a big and quality breaker bar ( one that wont break and you may hurt yourself) say 400mm long , then all you need is a very small extension( the smallest one you can buy), you dont need a socket at all. The 1/2 inch will fit in the pugs you have to undo, just make sure its all the way in when you put load so it doesn't slip.
