    Planning ahead for winter (?!) will be looking at hard brake lines.

    Has anyone any experience of these.

    I looked at some of the SS kits online but figured if the originals have lasted this long - if these are decent quality - they will outsee me ……

    cheers

    To be honest it would probably be cheaper to buy a roll of brake line plus connectors and a bending and flaring tool.

    But if you do buy those, don’t buy copper. Copper nickel is far superior than just copper, less prone to corrosion and splitting. If your confident at making hard lines then stainless is the way to go, but it’s harder and less forgiving to work with than copper nickel.

    To echo Huw, I did all of mine last year using cunnifer (cupro-nickle), a cheapo pipe bender and a flaring tool.

    Copper is an absolute no no and a good reason why illegal in the US on brake lines!

    mid my experience is anything to go by, the copper ones fitted but the PO had all “work hardened” and perished / cracked at the callipers inside the connector / flared part!

    having said that, I did buy copper to bend into shape first and get the pattern right before making the final items.

    Ps. Total cost of doing all (excluding the very long one that goes all the way back - which was already cunnifer) was under £50!!

    Thanks for the info .

    I did wonder about doing it myself - but wasnt sure how hard it might be .

    Certainly going to have a browse for some equipment and have a look. If you did it for £50 Ali - its worth having a go ............

    This flaring tool worked well for me ...

    This tool is posher and gives a cleaner finish ...

    Extra fittings if you want to do more pipes ...

    OK maybe a little over £50 but way cheaper than buying pre-made ones. If you are taking off the existing ones, you can use them as a template.

    For some of the bends like the rear brake drums I used paint tins and sockets to achieve some of the bigger and smaller radii.

    Which ones are you making?

    Ali - that’s brilliant mate - Thank You.

    Initially I’m doing both fronts as they have had some tough times .

    I’m replacing the calipers etc .and everything is rounded off - and worse for wear .

    Will probably move onto rears in due course .

    Thanks again

    Most welcome! Good luck with it and keep us posted. I literally saved hundreds doing all of mine and the fuel lines at the same time.

    This one at the front (as you can imagine) took a bit of time

    Looks good Ali.

    It’s a planned winter project so I’ll try and get a bit of practice first - and then I’ll have plenty of dark nights in the garage ……

    thanks again

    I do like the idea of making the shape first then doing a neater version

    you will also notice it’s longer than it needs to be at that point - it was flared as practice and to stop the first fitting falling off before I had bent it into shape. After bending to shape the fitting can’t slide past the corners, so you have to put it on first. Did that make sense?

    i think it makes sense - you can’t flare one end - shape it - then slide all the fittings down as they won’t pass the corners .

    Good tip

    Yes i see, thought maybe you'd done the remaining bends and keenly flared it before sliding the last fitting on :p

    Not this time but done many a dumb thing like that before :p especially on electrical connectors I’ve soldered meticulously well, only to have to de-solder and put the cover on the cable ! :(

    Edd China was making up fuel lines and brake lines on one of his recent videos which could be helpful?

    This is the one

    Always enjoy watching him at work and honestly makes it look easy.

    Thanks for that - always good to see it done .

    His Range Rover looks a bit rough mind

    I use the Draper version of this tool and it works really well.
    It is also small enough to use in tight spaces on the car if required.

    I also bought one of these, which saves a bit of time, if you are using a coil of pipe, and doesn't cost vey much.
