Brake lines, build or buy

    I'm replacing all brake lines and was wondering if I should buy a ready make kit, £40- 100 , or buy the make your own kit, which comes with copper pipe, bender cutter, and ends and flare tool.

    The latter will give me the satisfaction of doing it and I still own the tools but I'm concerned regarding leaks ECT

    Any thoughts or opinions

    Cheers

  2. The ready made kits I've seen don't seem to come with the long sections, so you'd you'd have to make some up anyway.

    If you get a good flaring tool, a box of unions and some knuifer, it's pretty straight forward - very theraputic, in fact. Needs a bit of practice with the tool to get a nice flare, but there's no reason why they should leak.

    Go for it!

    I was nervous of making my own at first for the same reason as you - would it leak? I took the leap and bought a 25' roll of Kunifer complete with 20x male ends for £25 and spent about the same on a flaring tool. A couple of quid on a pipe cutter too. I practiced on the old pipes I took off - only took 2 or 3 goes to get it. The beauty of making your own is you can make the pipes go where you want, not just the most economical route that uses the least pipe! I find the bending tools pretty useless - you're better off using your fingers. I did buy a deburring tool which is nice for finishing off all the ends. Go for it - it's very satisfying when you're done.

  7. All the above - just have a practice.

    I found the small bore bender I bought actually put a nick in the pipe if you weren’t careful, so I never used it for anything.

  9. Helped my son replace brake lines on his Golf mk2, using the Kunifer pipe. Brake line kits are available and we tried one, but found some sections not in the kit and some were too short. So my son bought Kunifer pipe and the fittings and a small pipe bender, which was tricky to get the knack of, and bending the pipes to shape by hand was easier and quite artistic and satisfying. None of it leaks and it all looks very smart.

    It's handy to be able to make your own. I have a Sykes Pickavant flaring tool somewhere- the dogs doodahs.

    Bending the pipe around something of whatever size you want the bend works for me.

    They don't even make those now. You need a vice to hold it but it takes about 5 seconds to clamp the pipe and flare it.

    Ok so after waiting a week and half for the brake pipe and fittings and the flaring tool to turn up it finally arrived,

    And guess what, that's it, it only does sae and not din, as I didn't know there was a difference I will now have to change the flare tool

    Are the fittings the same or do I need to change them aswell

    On the upside it makes nice wrong flares

    I was hoping to run the brake line this weekend don't look like now

    Anyone know where I can buy one of the self[​IMG][​IMG]

  15. Do they not do a smaller conversion kit for DIN? It’s just the dies that are different.

    I honestly don't know, and I now have the hump,

    Are the fittings the same?

    All din tools look totally different on the web
     
  17. Don't tell anyone but I used a sea flare and the metric connectors squash the back pretty flat when you fit them.. not leaked in the 5 years they've been on but perhaps I was lucky...
