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.

I have several sets of flare nut wrenches and get no joy from them. The problem is not twisting the lines but breaking the nut loose without rounding it off. Tried several sets and all the same, they spring open when subjected to the force needed to break the nut loose. The nuts have had a bath in penitrating oil to no avail. Sometimes they warp the nut instead of rounding it off. I have had sucess with carefully using vice grips but don't like it as it is very easy to mangle the nut. need some kind of wrench that closes the gap. mike ------------------------------
