Default Help i'm struggling on this.

As above, i'm trying to undo the cars original hard brake lines on the S6 saloon to change the flexi hoses and they're rock solid. Ive so far tried freezing them and can slightly turn the 11mm nut on the brake line but it's twisting the brake line also. This has happened on both sides at the rear. I have spare perfect lines removed from the 2.8 quattro donor car but have just realised if i'm going to replace all the rear lines to just under where the rear seat is i'll have to remove the fuel tank. Thats a big no no as the car is on the road and i can't move it. Can anyone suggest a way around this problem?

Pic of what i'm talking about.

You need a spanner on the rear hex to stop it turning, get yourself a couple of brake spanners to do it easier.
Here til thursday, enjoy the veal etc etc...

Do you really think i'm that thick? Been doing that all along but the hard line just twists and feels like it will just keep twisting until it breaks. I've got a brake spanner.

Chop through the clip and use a grinder on the braided line metal part if you don't care about it

Remove the assembly through the hole (there should be enough flex in the hard line).

Lots of heat should be enough to undo it or use a dremel to cut a groove in the remains of the ferrule which will allow the brake nut on the hard line to be undone

Thanks Mike,what i did on the other side was hold the hardline with mole grips as it was worse than the one pictured and just unwound the bf goodrich hose.

Are you saying i should just heat up the hardline where the nut is to free this off?

If all the above fails, or as an alternative, you could cut the hard line in a suitable place, fit a female union and flare the pipe. Then make up a new male-male pipe to replace the section you cut out.

Hope you get it sorted

Just heat the complete assembly - just be careful as brake fluid is flammable

I assume you have tried Plusgas Formula A?
I buy it in 2 litre tins and top up my little 250ml applicator tin; one of my bus club friends buys it in 5 litre tins!
