One thing I would like to add. I spent 40+ years as an HVAC tech, used single flares all day long and the only thing missing from this video is the use of a reamer to take the ridge out of the tube before you flare (any type of flares). Nice clean finished product, and a superb fit. Thanks for this video, nicely done,
EXTREMELY WELL DONE VIDEO! I have been an Automotive technician since the 70's and worked on a top fuel race team for three years. This gentleman explains EVERYTHING CLEARLY. Side note- You can always learn something new, you will never truly know it all. Thank you so very much.
I've bled my own brakes might as well learn to replace my old brake line. Amy way to minimize brake fluid loss after cutting a line? I recall a shop charged me almost $300 to replace a section of line once
I've seen about 10 different videos of how to flare brake lines and this is the only one that has not only spoken about but explained the alternative use of bubble vs double and to make sure you use what you have removed from your vehicle. Excellent step by step guide, only thing I'd add which makes it easier for viewers is you could add points in the video to click to the relevant flare you would like to achieve but that's a minor thing as people can skip if they wish. Thank you for taking the time to make this tutorial
Finally, after watching 3 videos about the same topic, on fourth I found the correct one. Very nice close up shots and straight to the point explanations! 👍 This is how it should be done ✅ Thanks a lot to your team 🤝
My car was in an accident the brake line snapped at the fitting and to my surprise it was the "bubble" so that is what I will put back on thankyou for this post!
Awesome. I am installing a line lock on my beetle and I am struggling to find metric to sae adapters. I'm just going to flare my own lines with the proper fittings. Something I have avoided, but this video will help me do that.
I'M GLAD THAT I WATCH THIS VIDEO...!! FROM NOW ON. I'M MAKING MY OWN FUEL LINES,BRAKE LINES,COOLING LINE,ETC... I OWN A 24 YEAR OLD TAHOE Z71, AND LIVING IN THE NORTHEAST.. EVERY LINE GETS RUSTY. NOW I'M GOING TO MAKE ALL NEW LINES MYSELF.. THANKS FOR YOU VIDEO..!!

I like your no bullshit type of teaching very simple you didnt go very fast which is key and to the point and most of all simple . I got one of those Hyd flaring kits and still learning on the different flares . It has some GM push dies etc thanks
Great educational and instructional video for the "do it" yourself at home mechanics! Thanks 1A auto for a proper brake line tutorial! This was helpful, I replace my corroded lines on my 02 4X4 Mitsubishi Montero.... using the bubble flaring tool with ease and confidence, my SUV is stopping better than ever! A word to the wise, check your rotors, pads, and brake hard lines and hoses periodically! Be safe everyone....
Single flares have their place in some applications, but NOT automotive. When I was taught the process, we were told those single flares are prone to splitting under the constant vibrations cars endure when driving. Always use a double flare.
I just got the Mastercool bleu hydraulic flaring tool, with the 3/8 and 1/2" jiffy tites for GM transmission and oil cooler lines. Its awesome. I just couldnt deal with using the manual tool anymore.
Manny thanks again to you Len and all those who make up the different videos. They are short,right to the point,very informative,and must I say very well illuminated. There’s nothing worse than watching a poorly lit video. Lester from Nova Scotia
Wow great video thanku i was doing single falresand it was leakinng now gonna do double.. so does a double flare fit into a inverted connector??i know it can fit but is that the right way?
I see that some auto mechanics use anti seize or copper grease to avoid the flare tool causing cracking on the end, for all it takes a little grease I would recommend to do that!
I know this is an older video but I'm hoping what I have to say might help someone out one day. I have been working on my own stuff and friends and families since the 1980s. For whatever reason I seen to be attracted to broken brake lines. I honestly cannot tell you how many times in my different vehicle that this has happened to me personally. The way I normally would fix it would be a compression fitting. At the time my friends that were mechanics are the ones who showed me how to use that. I can honestly say I had never had a problem until now. 5 years ago I was traveling at 50 miles an hour and put my foot on the brake pedal and it went to the floor. As I'm coming up to the red light I looked in my mirror and was able to get onto the shoulder safely. I was able to get my truck back to the house. Jumped in my other vehicle drove to the parts store picked up some compression fittings. I already had more than enough brake line in the garage. Like normally I went under cut my lines put the new piece in and then I bleed the brakes. That vehicle doesn't get driven much but it has been driven since the brakes were fixed. Christmas Day 2023 I was heading over to my family's house add halfway there to brakes went to the floor again. Since I don't live far from my sister's house I just drove there. I looked under real quick just saw brake fluid everywhere. The next day I put more fluid in there and had my friend pump the brakes up after topping off the reservoir. Sure enough the compression fitting is what broke. Now I could have just taken it apart and put it back together using some new line and cut away more of the brake line. I decided not to do that since I have seen numerous people make videos and tell you to never use a compression fitting on your brake lines. Never had a problem thought they were just talking to hear yourself. Everybody was 100% right who says don't use a compression fitting. Unfortunate enough to have an Eastwood store less than a mile and a half from my house. I picked up a flaring kit and picked up brand new brake line since the stuff in my garage is over 30 years old. It takes a little longer especially when you are flaring the original brake lines underneath the vehicle. Since my truck sets up high enough I don't have to use a jack. Now I have the Peace of mind knowing that this should not happen again. And if any friends or family ever have this issue and come to me this would be the only method I would use one last night I don't really like the person. -) sorry for how lengthy is was but I wanted to stress the point on doing something right. I love all the videos that have 1A auto puts out. Not only do I watch the videos I buy from them all the time. I still have an intake manifold to put on the same truck that had the brakes go out and that came from 1A Auto. I appreciate good videos and showing exactly how to do something.
May I know, is there any way to connect a 1/4" brake line tubing to a 3/16" brake line tubing? Because the issue is now, my car used 1/4" tube for the connection from the ABS pump to master cylinder. However, as I want to change my brake booster from single to double layer, I found that the master cylinder that fits to it is the one that using 3/16" tube. Can you give me the idea of any reducer or union or adapter that can be used? Thanks!!
Is the bubble flare SAE or DIN/ISO? They are different and incompatible with each other. The latter flare has a flat back side, whereas the SAE is conical to match the concave depression in the SAE nut. Double flares are getting more rare because the folding back of the metal often over-stressed it and caused a crack when formed. Bubble flares are less prone to splitting or cracking because there are no 180 degree bends like in the double flare.
Which tube nut do you use with double flare end? The "tube nut standard flare" or "tube nut inverted flare" fitting? Dorman 785-460D or Dorman 785-290D?
New to this. Planning to replace brake lines on a 1999 Durango. Seems relatively easy to flare copper lines. Question: once I disconnect my old lines, will it be clear which type of flare the old line is? Once a double or bubble flare is crushed don't they seem to very similar in looks?
Fantastic tutorial , but I would like to know how to double flare 3/16 304 Stainless Still brake line, so far I haven't found any information regarding it. I would appreciate your help please.
Very well explained. Would add that you should only use quality tools to do this job: cheap tools may cause poor results. Also, ensure that if you use copper nickel brake piping it’s is copper-nickel mixture and non-magnetic. If it is copper and magnetic then it’s probably substandard copper-coated steel.
No. (Otherwise they would call them double-bubble flare--which they don't.) I have both on one of my vehicles because a prior owner wanted to use pre-made auto-parts-store lines (double-flare) instead of pre-made dealership (metric, bubble) lines. The installation features "inverted-to-bubble" flare "adapters to go from one to the other as needed.

Regarding the fittings, in the video the fittings arent threaded all the way to the end of the fitting. Does it matter if fittings are fully threaded or not?

Yeah I use single flares on brake lines all the time and they never leak. It is the worst way but it does work if you know what you're doing
Yup, single flare = HVAC all day. Lower pressures than a vehicle brake line.

His tutorials are by far the best. 1A auto..... DO NOT STOP MAKING VIDEOS WITH HIM!
I put the line in the tool upside down and file it level. Then I use oil during any process to flare to prevent cracking.
Love the closeup of the three flares side by side. Great video.

Hi wonder if u can help in anyway. I've used double flare with a full threaded nut. My vehicle obviously had bubble flare . Will I be ok .
I would recommend reeming the pipe and filing the end flat, this allows the adapter to fit flat resulting in a perfect flare
Awesome..

Plenty of old cars run single flares , never had a problem with any
Probably because they don't have power brakes. Less pressure.
Probably because most of their owners died when the brakes failed

How does your tool cut through the brake line so easy? This rental tool from Autozone goes tight within a half turn
Very well explained. Give this man a raise.
