How to Double Flare & Bend Stainless Brake Lines!

Published at : 13 Dec 2025

I needed to make a couple short brake lines for my car. The lines I bought two years ago are stainless so I want them to match. I bought a roll of stainless tubing and a double flare tool to use to make them.

With the right tools and techniques you can double flare stainless without really expensive equipment yourself in your garage!

Here is what I used
