Stuck hydraulic brake hose

Help!

I have a hydraulic disc brake hose that I cannot remove from its master cylinder (lever assembly).
It's a Shimano Deore M525, which has a resin hose that screws directly into the cylinder (as opposed
to ones like the XT version, where the hose attaches at a right angle via a bolt).

The problem seems to be that the assembler torqued down the retaining nut too tight, and crushed the
sealing olive too far into the cylinder. I managed to remove the nut, but I can't free the hose.
I've tried pulling the damn thing as hard as I dare, but I'm afraid the hose will break leaving a
stub deep inside there, and then I'll be SOL. I also tried squeezing the lever to pop it off via
pressure, but that didn't work either.

Any ideas how to liberate the hose without ruining the master cylinder?

Thanks,

--AV

Perhaps a Dremel with a small ball mill to cut through the olive and the hose? A cutoff wheel
couldn't get close enough. I've no experience with XT's. You say the hose and olive are inside the
fitting? I have broken off the barbed tube on a Hayes master cylinder so I understand your concern.
It didn't take a lot of pulling to do it.
