Brake lines

[Cape Codder]

To connect two lines use a flare nut on each line with a coupler to connect. A compression union is a different fitting that has no place in a brake system.

^^ x100 on that. Their use in a hydraulic brake system is illegal in many states, including mine.

your thinking about the wrong thing ..
I am not talking about a crappy household pluming compression fitting ....
they are unsafe for use on any and all brake systems !!!

I have been replicating factory brake lines for over 30 years
and I don't use household pluming fittings on automobiles ..

I am talking about a automotive brass fitting that the local napa store calls a union ,
it is one piece and has female threads on both ends and it accepts double flared automotive brake lines
that have the correct fittings already on them .
I start with premade straight lines with the correct fittings already on both ends of the brake line.
then I cut them to the correct length if needed and I double flare the cut end reusing the original fitting .

I just use the generic ones I can get from the parts stores- come in various lengths and I can shorten and bend them to my will. Buy you a decent bender so you don't kink the lines and above all else, when shortening a line and forming a new flare, DOUBLE FLARE the lines. Don't single flare a brake line- that and compression fittings will lead to a brake failure. Brakes are not a place to cut corners.
