After finish the cut of tubing, you will notice that the tubing hole is compressed and unevenly closed which will not allow a smooth flare.

So, must clear the edges with a reamer before you start flaring. Reamer usually attached to the tubing cutter. If not, collect it for your job.

Smooth-Out Inside Bore Of The Tubing

If you skip this step, the line can crake or split when you try to make the flare.

You can use a cone file to smooth out any uneven metal or burrs on the inside hole of the brake tubing.

Insert The Tubing Into The Flaring Tool

Now, time to enter the tubing into your flaring tool. Lower the cone of the tool down and tighten until it is set in center position over the tube’s end.
