making brake pipes

So as always, you try and fix you defender and break something else.
Todays job was to replace the bushes in the in the front of the a frame and while undoing one of the bolts, i squashed the brake pipe with my spanner giving me a nice shower.

Question, i've never made new pipes and don't have any of the stuff to do it yet.

Any recommendations or tips for a beginner ? are they all standard size and thread fittings pipe diameter etc?

Thanks in advance!

Standard size 3/16”
Use Kunifer and not copper and get one of these. Practice the flares on some bits of pipe and away you go.

Pretty basic stuff, have a look at the You tube. Several video's on "how to" also showing the different kits available. Good one's by Britannica restorations ltd. As above do some free practice before making actual ones.
What year is your Landy?

Thank you both, and i take it i need to get the metric m10 x 1 fittings?

And as I found the first time I made a pipe, remember to slide on the unions before making the second flare

That is why I was asking about year. In 1980 Land rover said they were going metric and some stuff was but not all. Now for some reason My 1990 Ninety has imperial brake fittings [I have owned it from near new so no one has cobbled it] Why ? when others from the 80's are metric! Tdi on should all be metric.

Sorry, i didn't see that last bit, must still have brake fluid in my eyes

SAE FOR OLDER DIN FOR NEWER

For a male thread, ie for screwing into the caliper, it's a convex flare (or first/single operation). This gives the "domed" part on the brake pipe itself to create a sealing face when inserted into the caliper. The T piece will require these fittings too as it's an all female T.

A concave or second/double operation flare is required when you have a female brake fitting on the brake pipe, eg for attaching onto the threaded part of the flexi hose.

Actually get this one. I struggled for a long time (years) with the cheap multi piece sets you get with the little round dies. When I eventually gave up and got this one I was cursing myself for not spending a little more and getting this one first time around. It is much easier to just and gives a much better finish!

I’ve ordered the good type of pipe, one of those fancy flaring tools and a good bender as well as a few packs of fittings for fingers crossed, I can cobble something together.

Thank you!

Spend a bit of time routing the pipe nicely, nothing looks worse than a poorly bent and routed pipe.
The straight bits are actually the hardest to get looking nice.

I bought one of those pipe straighteners that is basically a tube with a plastic guide at each end. It’s crap.
