Brake fittings (conections to front UFO flex hose) frozen,

I've had to replace all the flex line connectors on all our 1990-91 Audis,
as well as most of the rear brake lines completely, Alan.  Local FLAPS have
short sections of brake line with metric fittings I've spliced in where
I've not needed to replace longer lengths.  Had to cut and flare the
existing lines to splice in.  On UFOs, I've also had to replace the short
piece of line that goes from the top to the bottom of the caliper.  Used
the same source.

Subject: Brake fittings (conections to front UFO flex hose) frozen, 

I spent a frustrating two days waiting for penetrating fluid to do its
work, but as of tonight, I have still not succeeded in separating either of
the two fixed lines from the flexible rubber hose on the driver's front

After jacking up the car, I pre treated the fittings with liquid wrench and
waited a few hours before attempting to open. When they would not budge, I
kept adding the penetrating fluid spray and waited overnight to try again.
as of this afternoon and evening, I have only manager to round off the
upper nut, and partially round off the lower nut, with my 11 mm flare
wrench. I even used a vicegrip on the upper nut, but they both seem to be
welded to the intermediate flex hose. Besides Liquid wrench, I also used PB
Blaster, and as small amount of heat. 

I have put back the wheel and parked the car outside....awaiting some BTDT
advice from this group, thanks. 
(Patient is a '91 200q with the original hose and UFO calipers, I believe
the fittings have never been opened since they were assembled at the
factory, unless the previous owner did them in the first seven years and
