Sears sells this flare nut wrench, but only in a kit of four for about $35.  Worked great and well worth it not to ruin the fitting.  I could not find it anywhere else separately.  http://www.sears.com/search=flare+nut+wrench+set?vName=Tools&cName=Wrenches&autoRedirect=true&viewItems=50&redirectType=CAT_REC_PRED

Subject: 11mm brake line wrench

anybody have a recommendation for a good system to loosen the 11mm fittings on brake lines? Been through the usual wrenches and always wind up with vice grips.
The wrenches always seem to warp the  nuts.
