Hi All - I am trying to make up a couple of brake lines and can not seem to make consistently 'even' double flares. I get about one in five the way I think they should be. I do not recall having this much trouble when I did this in the past. All 'trade secrets' are appreciated.

Are you using stainless lines? They are hard to do.
You do need a good quality tool for this job, also.

Which tool?

Make sure you cut the tube off really straight. Make sure the piece of
tubing is really straight. Chamfer the inside AND outside of the tube
carefully.

I've done hundreds of those 3/16" double flares with a $50 tool. When I
started I had your kind of luck. Take lots of care in the prep work and
you can have good results. A better way is to own a better tool. :^)

I am using a Craftsman set and was using a KD set, both with the same result. For now I am making a bunch of 'samples' until I can get it right.

It sometimes helps to put a drop or two of brake fluid on the "flare adapter" for the 1st stage and the 45° part of the tool for the 2nd stage. Also, being very careful to have exactly the right amount of tubing exposed above the bar part when the tube is clamped in helps with consistency as well.

I gave up on double flares. I used single 37 degree flares as much as possible now,
Easier to do ( like possible) and actually reusable.
double flares are not supposed to be reused, yes everyone does, but youre not supposed to.

Yes you do need to bye 37 degree fittings.

Did I mention they are reusable?
