That's a great idea.
I usually put the vice grips on the flare nut b/c as others have mentioned,
line wrenches don't work, they just strip.

Will have to try this technique next time.

A trick I often use with brake line nut wrenches is to place the proper
wrench on the nut, then clamp the wrench with a vice-grip type of
locking pliers.  This helps keep the line nut wrench from spreading
under extreme force.  Really helps when working on 35 y.o. Fiats.  And
Vanagons.
