it's not the new hoses
it's the little (bolt) to loosen original hose from metal hose those things are so hard to loosen mostly you wreck it

I know what you mean advevo. To do the job properly you really need a special brake spanner that just slots through the brake pipe and then drops down on the nut and grips it more firmly than an open ended spanner. I ended up using mole grips (I can hear the wince from Evoboy now
U need a Flare nut spanner , and I think the size is 11mm ,I'll double check and let u know.Maybe u have a Snap-On tool dealer over there , if not then Facom or Stahlwille are also good.
Usually without the correct tool the various nuts are damaged.
