Brake lines and fittings

Having a go at fettling brake lines and need to know the brake
pipe size and thread size of the parts used on imperial land
rovers.
In the past just gone to local garage and got the to make up
bits but I'm fed up with rusty fittings that twist the pipe
while I'm cursing them so I'm going to order some nice new
cupro-nickel pipe and brass fittings but I've no clue as to
which sizes I'll need.
Awaiting your sage advice.

1/4" from the reservoir to the master cylinder but 3/16 for the
actual brake lines i thought. If you use kunifer you'll need a
decent quality brake pipe tool for the flaring. Sealey do one
which is adequate, cheapest at about £80ish.

Anyone got any idea what sort of pressure a 1/4 brake line has
to deal with ???
Just wondering as we use miles of 1/4 pure copper tube for
aircon work ....and it has to cope with a min of 8 Bar :-?

There's no pressure on the 1/4" pipe, it's only the feed from
the reservoir to the master cylinder, so air-con copper tube
should be fine, easier to bend and flare as well!

80" have whole system in 1/4". Later models are 1/4" from
reservoir to master and 3/16" for rest of system. You can get
away with rubber pipe from reservoir to master.

Ok i am surprised - i didn't think any motor had 1/4" (apart
from lorries maybe). I have a landy 68 and 71 which have 3/16 on
them. So you are saying that later they changed to 1/4 (what
years?).... and then changed back.
I wonder if it had to do with the front drums bleeding problem
due to the incorrect positioning of the bleed nipple. Not that
it's a problem if you reverse bleed or simply alter the piping
so that the bleed nipple is on top. tbh reverse bleeding is
better for one man bleeding i think - quicker and easier from
one place by the wheel (like they do for motor bikes).

When I say 80" I mean early Series 1 1948-54.

I concur, early S1s are difinately thicker, think I'm right in
saying people use a union from a 101 clutch system to allow
fitting later wheel cylinders without having to replum
everything.
Remember IF you use solid copper pipe make sure its restrained
VERY well as otherwise the vibrations they get in a vehicle can
means they can be prone to fortegue, steel or that slightly
silverycoppery coloured stuff I forget the name of (my tubing of
choice) shouldn't suffer this issue unless its spectacularly
badly fitted (though as ever I have seen landys with complete
runs of brake pipe unrestrained which hadn't been picked up on
an MOT).
