I was needing to shorten some brake lines and reflare the tubing for the fitting. I looked in a local industrial supply store catalog for a flaring tool and it had two different types. A tool with a 45* flare and one with a 37* flare. What's correct for my 70 GS ? o No:
Just a word of advise on the flaring tool. Don't buy cheap on these because they are junk. Spend the money and get a good one from Snap On. They are about $100 but well worth it...if ya want to stop that is
