Brake flares - Everything you need to know-tips, tricks and tools

- This is a detailed video showing the different types of brake flares, a variety of budget brake flare tools, common brake pipe materials and tips and tricks to get the best brake line flares. Last but not least the video touches on the dangers of buying cheap kits from eBay or Amazon and why it’s not recommended to use compression fittings on brake lines. CORRECTION - A subscriber has pointed out that the cutting wheel and groove shown at 14.47 is not actually supposed to line up. My mistake!

If only all videos on UA-cam would be that good. 😮
Wow...high praise indeed. Many thanks. Mike
Thanks for this video Mike. Top tips again. I had bought the wrong type of flaring tool in the past obviously and previous efforts had failed so I bought the one you suggested here with perfect results. Brakes almost sorted now
Great news! Yes, I bought the wrong flaring tool first time round. Mike
Easy an simple when you know the process.....Good Job, thanks for sharing your Project with us...
Thanks for your comments.
Very informative, thank you! I need to replace brake pipes on my BMW and now I know which nut and flare I need. Now, I only need to find the right tool... (or maybe I'll use the wrong end of the SAE tool I just bought)
Yes...I bought the wrong tool the first time I went to repair the brake lines on my Merc. The tool I use in the video below works great:

Dude, thank you so much, u couldn't explain it better. I was suddenly puzzled realizing i couldn't tear din flares from sae & was blank about the tools. I was about to buy a din tool which isn't for my car
Thanks for your kind comments - really appreciated. I was the same before doing this video. Mike
I just want to say thanks for the video, only one that showed the differences between DIN and SAE. Just put new rear brake lines in with an SAE bubble instead of a DIN bubble, but the lines was nicopp so the fittings kind of crush it into place anyways. But now I know I was using the wrong tool.
Thanks for your comment - yes there is often some confusion as to which flare to you. Glad yours worked out. Mike
Well explained.
Thanks.
Hi Mike thank you for your videos, mate; very helpful. A question from full me; I'm looking to buy the in with wee tool for 3/16. I'm in Scotland and have an Astra so, do I buy the SAE tool and do OP1, then OP2, or do I have to buy the DIN with just one OP, if you see what I mean. My Ol'boy has a Mazda, so I don't know would DIN suit his car. I suppose what I'm trying to say is, will the SAE with the two OPS, make a DIN bubble. Cheers mate.
You can't use SAE tools to make DIN flares, and vice-versa. OP1 with an SAE tool looks like a DIN bubble flare, but it isn't a true one and shouldn't be treated as one. As to which type you should use for which car, you just have to confirm which type the car uses. If (say) you're replacing a brake hose, you can check the flare type without having to disconnect anything by getting the new hose and looking into the end that screws onto the metal brake line.
Good video
Thanks for your comment. Mike
excellent video
does the shape of the femail socket on slave/master/caliper ect make any difference to the fittings you should use ?
also if making complete new brake systerm (kit car ) what is prefered SAE or DIN
any advice would be great
Thanks
Thanks for your comment. Yes - the female on the slave/master/caliper will determine the fittings to use. At approx 4.3 in the video it shows you how to recognise the different female fittings.Once you know the female fitting, you will be able to determine whether to use DIN or SAE.
I'm not sure I would describe one type of flare as 'better' than the other - they are different but both work. DIN flares are not designed to be opened again and reused once tightened down. The type of flare to use will be determined by any fixed variables such as the female fittings on the slave/master/caliper.....and the origin of the car - UK or USA etc, Hope that helps. Mike
@@MikesMercsandothercars helped me out no end thanks for thaking the time
Thanks for sharing, very interesting. So if I want to replace the flexible hose lines on my calipers, I can’t re-use the factory DIN fitting? I would have to cut and re-flare the factory hard lines?
Thanks for your comment. In theory yes...but in practice, most people reuse the existing fitting and if it doesn't leak, you are good to go. Mike
Hey I got the Capri Tools CP21110-316 Double Flaring Tool and it's the handheld version you showed in this video. Has very good reviews but I am getting lopsided flares using Copper Nickle brake line no matter what I do.
The Nickle Copper line is from The Stop Shop which I think is US made company at least they ship from the US domestically. It was $35 on Amazon for 25ft.
What is wrong, can you help me? I have a video showing my flares but it seems my posts with links get deleted all over UA-cam.
I know this is an old post but I just did the same thing with the same line and tool, and I found that by backing the tube up roughly 1.5-2mm from where it is supposed to sit forms a proper flare.
I think it just because nicopp is so soft it is possible to squish it right down. I also just file the end flat after using a tube cutter, I didn't need to bother with giving a chamfer to the tube.
Excellent presentation. Could I possibly ask for some advice? My daughter’s VW Campervan 90s or early 2000 plate 2.4l 5 cylinder has a leak on hard pipe from pump to injector’s. Can you advise which flare for this pipe. Also is it metric or imperial, and best material to use for replacement I.e. ss, mild steel or Cunifer also wall thickness… Many thanks.. Sorry I forgot to mention pipe from high pressure pump to injectors, apologies…
Hi - I am afraid that I am no expert on these vans so may not be of much help.
You will struggle to flare stainless steel manually, and even steel is incredible hard to flare with simple hand tools.
Is the leak from a pin hole or split in the hard line, or is it at a joint? I cant quite visualise the issue.
How long is the fuel line and can this not be replaced?
Mike
@@MikesMercsandothercars Hi Mike, many thanks for replying managed to find some on eBay will replace damaged ones and use as template to hopefully reproduce in ss or mild steel, thanks again.
@@johnmcgiv1 Hope it goes well. Mike
Hi Mike.
By the way, do you know what type is used in the r107 for us market?
I am interested on my 560sl.
Thanks
Thanks for your comment - to the best of my knowledge, all Mercedes R107's will have the same flares whether is Europe, USA or Japan. Mike
Thank you Mike
I'm having a lot of difficulties trying to flare a steel brake line on a audi any tips? I've the two 10mm nuts it's not holding it enough it's just being pushed back.
Thanks for your comment and sorry to hear you are having a problem. Steel brake line tends to be MUCH harder to flare than copper which could possibly be part of the problem.
1. Are you doing it in situ?
2. What kind of tool are you using?
3 I am assuming that you are doing the right kind of flare for the nuts you have?
4, Where do you live?
Mike
Here is the video of my flares using:
Capri Tools CP21110-316 Double Flaring Tool with 90% Copper + 10% Nickle brake line tubing from The Stop Shop:

Hi - I replied on your channel but can you confirm that you are using 'punch grease'? Mike
Why did you buy SAE tools for your Germans DIN pipes????? The flat base of DIN will not seal well on a SAE fitting and vice versa.😅
Thanks for your comment. I used a DIN tool to fix this Merc.....although I did have a SAE tool for this video. My next vid is all about fixing rusty brake pipe on SL55 AMG ....it was all going so well until the brake nipple sheared. Mike
Nissan uses DIN on their ABS
Good to know - thanks for your comment. Mike
I would like to say, your cutters which you keep saying are not lined up are correct, that groove should not be in line with the wheel cutter.
Thanks for your comment and pointing out my mistake. I have updated the description accordingly and really appreciate your feedback - its how we learn Mike
The grove is so you can “hopefully” cut an old flare off the tube, with minimal wastage
