What I've done before is to use both - put the flare nut wrench on the fitting, and then clamp the Vise-Grip onto the wrench end. It will keep the flare nut wrench end from slipping, and you avoid tearing up the nut with the Vise-Grip.

That's a great idea!

Same deal here. The flare nut wrench should not grow in diameter as you apply force. The vice grip pliers really help with keeping the flare nut wrench securely around the nut. Last thing you want to do is bugger up that brake line part.
