Either you have an external leak, which should be very evident or your master cylinder is leaking internally at the piston seal and needs to be replaced.
:tisk: That would probably come apart on the first brake application. Are you buying preflared lines and then doing your own bending? That would be the way to go.I was going to repair the line with a compression fitting
I know I have seen pipes at Napa, but maybe they are for something else. Never paid that close of attention since I was not in need.The lines must be fabricated.
