Yes. My favourite tool for loosening brake lines is a small, four-inch
vise grip. All wrenches, even flare nut wrenches, usually start
rounding the flats on the nut before you can apply enough pressure
to start the thing turning.
Flat-jaw vise grips are preferable, but curved-jaw will work if you're
gentle and patient. Clamp the vise grip across any accessible pair of
flats. Leave the other flats for wrenching once you get the thing
loose. Wiggle the v-g back and forth - gently. It will loosen as it digs
divots into the flats. Get a tighter bite and wiggle some more.
Repeat until your bite becomes solid, then continue wiggling and
believe me the nut will loosen. You're not home free yet, because
usually the nut doesn't release from the tubing without another
period of gentle wiggling. If you're patient you should be able to
simply "worry" it off. Once loose, you can turn the nut with an openend.
If necessary, touch up the chewed flats with a small file.
Occasionally the nut will simply not release from the tubing, in which
case the whole tubing section is trash. I believe 405s (and all
Peugeots?) use non-ferrous lines, so this shouldn't be a problem.
Your torque may vary, etc.
