GM Brake lines? Double flare issue

[uluz2a6]

I have an 87 Regal.

I'm trying to double flare my roll control brake line. Only my "kit" has 3/16 & 1/4 inch adapters. Those wont fit. Ones too small, Ones too big. What size do I need? Do they make a 1/8" adapter?

Thanks
Curt

1/8 is smaller then 3/16

did you de-bur the line after you cut it? if not, the proper adapter won't go in

yeah, 3/16 should be the match. I'd try using a small straight pick and push it into the line and spin it around and pull in and out. Probably some burrs in there

X2 on the 3/16". It normally fits loose so it won't get stuck in the end of the tube after flaring.

the roll control end or the other end. They may be metric
