Can anyone confirm the correct dimensions for brake pipes and union nuts for the Felicia and Favorit?

My guess is 3/16 diameter pipe and M10X3/16 male union nuts. The originals appear to have a single flare.

Also on pipe flaring tools. I understand that many people say cheap = crap flares, but there's got to be one that produces adequate flares on Kunifer pipe and happens to be cheaper than the rest. Anyone have any recommendations on a good flaring tool?

Some of the cheapest I have come across include these at toolstation. This one is £10.18 (which from searching on the net appears to be the same as a rolson branded one)

Information...

and this is £18.98

Information...

all the brake pipe unions are metric M10x1mm fine pitch, some have convex or concave seats depending on polarity so you'll need both types

I just bought a roll of brake pipe £7 for 25ft from Partco/Unipart

I have an ordinary flaring kit,will that do for the favorit brake pipes,whilst changing a mounting one of them nasped off and it does not look like a normal flare shape its kind of like a UFO shape at the tip,will a normal flare work anyways?

You need to be able to make both kinds of flares as Tom has said. While I was making the pipes for the rally car obviously I didn't use standard routes and changed to stainless braided hoses, the ends were mostly as they would be anyway.

Got a pic of the UFO?

"Car Mechanics" magazine did a recent test of brake pipe flairing tools . They found that the really cheap ones were very intermittent in getting good quality flares . Some times O.K. , some times scrap. If you can take the old pipes to a motor factor who does brake pipes , they will makeup and flare to suit your sample.

No it is not convex or concav,it is both together,starts off as a convex then goes into a concave, like a UFO,so no tools to make it, Damb it!

Ok on the internet it says its called a ISO flare or a bubble flare and it turns out you can use a normal double flare to make one

I've got a sykes pickavant flare maker. It wasn't cheap (about £90), but it is AMAZING. Proper tool. And when you're talking brakes.....
