DIY stainless brake lines ( hardlines)

[mc1984ss]

On my next project it is going to require all custom bent brake lines. I would love to do stainless but am getting a little gun shy because a lot of people seem to struggle with them and getting them to seal. I am not sure if this is due to faulty tubing, a bad flare tool or???? I have access to a hydraulic flare tool so I feel.very confident in that. I've made my own stainless lines in larger diameters so I know what I'm up against. I've just never don't my.own stainless hardlines that see that kind of pressure. I'm open to tips and suggestions. I'd also like to know who sells a coil of quality stainless brake line. Thanks!!
