I have made all new steel brake lines from long tubing and the fittings (the whole car) for several old cars that I have owned. Two things that I do which really seem to help is: 1) when you trim or cut your steel line to length (as a few people have said before) de-burr the inner part of the tubing and I also radius the outside of the tube, this really helps the double flair form correctly. 2) I use a drop or 2 of fresh brake fluid as lubrication on both the bell-form insert and again on the final pointed tip when forming the double-flair into the steel.

Making really nice brake lines from scratch is an art-form & just like any other skill you can get better at it with practice.

Nailed it.Radiusing the outer edge,lubricating just a drop or 2 makes a better result.Had'nt thought of the small steps ya take to get it done right,leak free.Practice, experiment,learn etc..
