Topic: help with porterfield brake lines
Working on my 92 grand prix for the detroit race. I ordered my Porterfield stainless steel brake lines. The problem I am having is that the stock male flair nut on the existing stock steel lines won't thread into the porterfield fittings. The original wheel brakes lines have a deeper female coupling. When I explained the problem to Porterfield the technician didn't understand the problem. Has anyone else had this problem with the GM flair nuts?
