How do you make bubble flare pipe ends?

[staleg]

Jaguar rear calipers needs bubble flare brake pipe ends to seal properly.
I have been told two different ways to make these flares:

1. Buy a bubble flare tool.
2. Use the more common 45 degree inverted flare tool and skip the last operation (the one that inverts the flare).

I have a good 45 degree inverted flare tool already. It's written in the users manual that if I want to make "Citroen flares", I just skip the last operation. Do they mean bubble flare when they write "Citroen flare"?

Is alterantive 2 just as good flare as alternative 1?

if you have a flareing tool it tells you on the box

Just use op 1 tool only, op2 should only be used ( after using op1 obviously ) when coupling to male threads ie brake hoses.
