Okay I messed up big time and managed to wreck the rear brake lines 
I couldnt get the T-piece connections undone or the one that goes to the driver side caliper so in the end I had to cut the brake line to drop them all -
So that bit above it wrecked, and the 3 connections on the T peice are kind of rounded..
The end that goes to the connection near the engine is still okay but makes no different really -
So im left with this and need a replacement -
Whats the best way to go about this and how hard is it to make one up?
As its brakes I really need to makes sure its done right so may even see if a garage can do it?
Also one more question..how do you get the piston to go back into the caliper as I cant get 1 of the pads to go in as its came to far forward and cant figure out how to push it back, even after removing bleed nipple etc as I thought that would work??
