This is the stage I like to call everything is rusted together and rounded 
Left rear won't come apart which is really annoying considering the copper pipe was replaced in Sept...
Right rear 2nd hose to pipe... I've gone from the 11mm spanner, to deep socket and once those have rounded it off tried to grip with mole grips and it won't budge.
I have tried turning it the other way just to be sure and giving it a few taps with a hammer to loosen it up but alas there's a frustration dent in the garage floor
