splicing leaking brake line

actually never use a single flare on steel line, only on stainless steel line. why? regular steel line has a seam that will split if only single flared and SS line does not have a seam and can be single flared. also, unless your flare tool is designed for SS line, don't flare it! you will break your tool. sorry 64 dartwagon, but you cannot run a single flare for non high pressure lines, a flared line is a flared line. it just depends on SS or regular steel. it is ok to have single flared SS brake lines since it has no seam and wont split.
