Was that a DOUBLE INVERTED flare u made or a single flare???? Brake lines must be double inverted flare. The double flare is not all that hard to make. The end of tube must be cut square with a tube cutter. Champfer the end of the tube. A file will work for that. Be sure to debur the ID of the tube after cutting it. Then flare it. Use some brake fluid as slight lubricant for flaring operation.

I would use the standard steel brake line because that is what has been used for so many decades. Go with what u know.


Nope, I just put a bolt in the tube and bashed it with a hammer for a while. :) Of course it was a double flare, that's why I practiced! Any knuckle dragger can make a single flare. The two tricks I've found: de-burring the inside of the tube with a slightly over-sized drill bit works much better than the de-burring tool on my cutter, and putting the flare tool in a vice makes things much easier to flare.

I decided to go with a coil of steel tubing. My goal is to have a restored driver, not a concours car, but the Cu-Ni tubing is, well, copper colored!

Thanks for all the thoughts.
