I saw your sig when I was looking to see what year car mdevour has. Chances are his is the double flare. Mdevour - please put the year & trim level of your car in your sig.

I found some 6mm line online but it was over $5.00/foot. None of the local parts stores around here have it. I tried NAPA, Advance, Autozone & Carquest. I may just use 1/4".

i've used standard line with bubble flares and have never had it leak, so i think you'll be ok

I have redone the entire brake lines on MANY cars including Cadillacs and plenty on bonnies(Cadillacs are the WORST!!). I use different length tubbing and use unions to tie them together. As long as you get them tight, they wont leak. I have never had one come back leaking. As far as the 6mm line goes. I use 3/16 and put the original metric nuts on it. A lot of times I have to drill out the old line from the old nut cuz it rusts in there. But this method works real good. If you are having problems with the line splitting when you flare it then something is not right. Either the tubbing is really cheap and thin, or the flaring tool is junk. A good quality flaring tool will make all the difference. I have that Performance Tool flaring tool and it works OK. Sometimes it doesnt want to get a good flare though. It will turn out crooked or oblonged. The better quality the flaring tool is, the better the flare. Been there, bought that. And I use my Bosses flaring tool instead.

Hi Ted,

I think we cross-posted. I didn't see your message until I logged in today, despite it being sent before mine.

It took me a couple of tries, but I finally got the signature feature turned on and working... I'm not usually so forum-challenged!

I'll be starting to take things apart tomorrow. If it'* anything other than double flared I should find out soon.

I've done a lot with cars over the years, but brake lines were not something I ever felt comfortable with. I've learned some things in the last couple of days!

My thanks to everyone. I'll report back on my progress.

the murrays near me has a bubble flare tool kit.


idk if you have murrays where you live though. but csk owns them, they might have the same kit.

I took the rotted brake line off the Bonneville just now. I believe I have bubble flares!

Just so I don't make a mistake with what tool I'm buying...

Some say they'll make bubble flares.

Some say they'll make double flares.

A few explicitly say they'll make both and have extra dies.

I've read that the first half of making a double flare leaves you with a bubble flare, and that you finish it off with the other side of the die...

Does this mean that I can buy any double flaring tool and it will make bubble flares, or not? Or is it a cheat that doesn't really work?

I'd like to get a tool that will do both kinds, since it'll make it likelier I'll get some use out of it. I don't know what I'll find when I go shopping, yet.

<LOL> Yep, there'* Murray'* in my neighborhood. I'm in Detroit, too! Howdy neighbor!

There may be bubble flare tools that can make a double flare, but a typical double flare tool will not make a functional bubble flare.

Single, double, toil and bubble - fluid leak with wrong tool trouble. (Sorry, couldn't resist!)

thats funny cuz, many times when i say murrays on these forums, people say "wtf is murrays???"

but yeah, if you ask em for the loaners, they have both metric and sae double flare kits, and also the bubble flare kits. and if you want to keep it, you do just that. thats what the deposit is for. the actually encourage it. and theres no time limit on them, so if you keep the receipt, you can always return it for a full refund. i think the last time i got one of their double flare kits it was $19.99. (actually still have it).

Thanks. I wanted to be sure of that.

Absolutely GREAT!! Thank you for the belly laugh, Bill!

Sometimes Shakespeare sounds a little like Doctor Seuss!

Be well,

Yep, there are still a few businesses that haven't disappeared into the ranks of national franchises. Meijer'* is another regional company. Vernor'*, Stroh'*, Saunder'* and Better Made are a few examples where only the name survives.

I may do just that. Shopping around today, I couldn't find a local source for a dual purpose kit I thought I'd like. Rather than order and wait for it, I can just get the job done and keep the tool or not, as I feel like.

Thanks a bunch, folks!
