Here is how I created a bubble flare brake line for my 1929 Ford Roadster hot rod using C4 Corvette brakes. I used an inexpensive double flare tool kit that cost about $25. With care every flare made came out with good results. It sure beats buying pre-made lines and trying to match them to your application.

I almost returned the double flaring tool I had just purchased for the job when I learned that I instead needed a bubble flare, but your video gave me the confidence to give it a try. This technique worked beautifully once I got the height of the tubing set. I found this to be quite critical, with 0.23" about optimum, for my tool and tubing anyway. Thanks for taking the time to share your experience!

Your DIY Bubble Flare looked as good as the "factory" one to my eyes. Nice "how to" demonstration. Thank you. As always, practice makes perfect.

thanks a lot man you saved me. I've been restoring trucks now for about 4 years. always had to do the double flare and didn't know how to make a bubble. I appreciate it and I like the song at the begining. good work.

Superb video, Sir. Thank you. Nickle-copper line cinches in the toolbar notches easier than steel, and will never rust. Most larger tubing cutters have a deburring tool built in- those small red ones are cheap cast junk now days, get dull, and easily crack.

You've no idea how much this video has helped me. Went to buy a really expensive tool for flaring, got to shop and it wasn't in stock, website said it was, left me really stuck, car was overdue MOT. Saw your video so bought a Sealey AK506 which does SAE flares. I know it's not how it's supposed to be used but really helped me out.

I freaked out when my small hard line fittings were unbreaklable and stripped to nothing. I did all of the tricks: Penetration oil, heat, vice grips. Making hard lines with the correct tools is MUCH easier than I thought... I used a 1/2" countersink bit to ream out the end and it worked great and kept the hole on center. Thanks for a great vid, it was a lot of help!

Notice how he is using the flat side of the clamping tool to make bubbles with a cheap tool. The hard part is not having go sideways on you. You need to leave more protruding than they say with the double flared ends.

Great video, thanks. My Sears craftsman double flaring kit doesn't work good for doing this bubble method. I had to rent a double flaring kit from my local Advance Autoparts and just use its adapter, the 3/16" adapter was concaved deeper than my Sears. I'm gonna have to look online for just the deeper adapters so I don't have to go to Advance when I need another bubble flare. Just like the in the video it's very important to keep the adapter straight.

IN THE PAST, I always just single flared a brake line & never had any problems! Now, I am seeing all this talk of double flare & bubble flare & most importantly, TO NEVER USE A SINGLE FLARE ON BRAKE LINES! NOW, I AM WONDERING HOW & IF MY FLARING TOOL WILL EVEN DO A DOUBLE FRARE OR DOUBLE FLARE? Honestly, it has been so long since I have done any brake line work that I am out of practice & go figure, I have to replace all of my rear brake assembly/both wheels & lines, & wheel cylinders, & probably a lot more! probably need shoe's & drums at least. a simple brake line failure has turned into a several hundred dollar job & when i looked up line flaring, this is all news to me!!!

@randyross2089 8 жыл бұрын

I've found that "chalking" [ i.e. Coating] the brake line with sidewalk chalk where the tubing clamp grips helps you make better flares. Give it a try--just avoid getting any chalk inside the tubing!

Question: I opened up my inline bubble flare tool & its been 2 years since I last used it. There is two 4.75 fittings, one is thinner then the other & the thicker one is black & marked 4.75B & the thinner one is made of a shiny metal & just says 4.75 which one do I use to make a iso bubble flare??? Why is there 2? What is the difference?

@theguch9038 5 жыл бұрын

With the bar upside down(no countersink) your making a mushroom flare, not a bubble flare. Not the same. I'm not saying they are not interchangeable. They may be. I think it depends on the type of line nut your using.

I wonder if you could use a compression fitting without the ferrules as a union to connect 2 bubble flared lines? I guess I'm asking if the taper is the same or close enough to seal?

+BestBuildPC Power of imagination - I was flaring 4.75mm or 3/16" tubing. DIN/ISO or “Bubble Flares” are the same for European and many North American vehicles. This was for my 1929 Ford using 1986 Corvette suspension and brake parts.

You'll also need a lot of time and practice. Or you could just wing it and hope that your bubble flares seal properly........again and again ect. But no worries it's not like your going to be in trouble if your flares fail. BUY A BUBBLE FLARE TOOL! This is not as easy as all these youtube vids make out. I have never once seen them test their flares. Spend the $40 bucks on a kit. It's a small price to pay for the time saved in redoing a line or 2 that didn't seal.

+diGritz1 - All of my joints worked well, no leaks. It's all about practice.

@diGritz1 9 жыл бұрын

+1929fordhotrod I practiced a lot too. I have also worked in tool and die/machining most of my 30 years of working life. I have repaired a lot of hydraulic equipment. Some with upwards of 40 or 50 lines running at anywhere from 5000psi to 12000psi and never had any trouble with leaks. After I stopped listening to all the advice and gave a little thought to the problem I figured it out so bad on me for not listening to my little voice screaming "THAT'S NOT RIGHT". In all fairness I will admit yours is the best out there. But it's not the only one and information can combine and mix. Most of the the rest are either out right wrong or fail to give a proper explanation of what this fitting is and how it works. But that's why I feel that the best choice is to buy a bubble flare tool. They can be had for $30 or $40, (found as low as $25), and that's a small price to pay for piece of mind. Or buy your lines cut your lengths and take it to a brake shop they will do it on the cheap. I will gladly tip my hat to you for your success if you can just tell me why you succeeded. In all honesty I figured it out and yes you did do it correctly but do you know why? You kind of mention it but glass over it. First it needs to be said, this is nothing like a flare fitting and does not seal the same way. This is a compression fitting and the seal rely on that. It needs to be clearly explained that if you over tighten the fitting while making it you will pre-crush it. Meaning it's going to leak..... a lot. And no you don't have to torque it all the way down to pre-crush it. This may seem like common sense but many have no experience with these types of fittings and will give equal weight to your video as well as any other they see. So at the very least add text that explains that and why all the others are wrong for those out there who don't know any better or have little to no experience with this type of fitting. My only desire is to make sure anyone who tries this has ALL the information before they waste their time and money and give up.

+diGritz1 Thanks for your detailed comment. Sometimes you will find yourself stuck in a corner needing to do a simple task without the proper tool and the tool is not available. I agree using the proper tools or equipment is always the best way to go.

@staffordsanpei7804 3 жыл бұрын

wrong! The side with the fitting doesn't have a flare.

@bcubed72 Жыл бұрын

Exactly. To do a bubble flare with a double flare tool, you HAVE to use the non-flared side. The factory bubble flare bends out at a 90 degree; the "correct" side (for a double flare) will get you an angled bend that won't seal.
