Thread: Regulations on brake lines

apparently it is.... unfortunately

I think the metal for regulation brake lines at a min is Cupru nickle, which is a copper alloy that takes bends, does not work harden, double flares without splittting and has a high burst pressure. Steel lines in smaller diam tend to kink on bending short and are harder to double flare. I am pretty sure landybitz on Evil bay has the Cupro lines sets. I very much doubt you could sell copper lines as brake lines in Australia.
Your '76 / '78 will be a mix of unf and metric! Its around the change over for landrover, but they still had drums of unf stuff for some things wit the odd bsf too!
Is that the SWB you got from rangitragic at Marybourgh?

thanks for that scott, i'll have a look.

No it's not for that one... dad is working on that one, i'm not sure what he's up to with brake lines so far. I have my own beasty that I'm working on... it's getting a few more goodies. look it up - thread is called Nicks 75 SWB or something like that

Oki was not sure which it was. I would double check the road worthy side of the brake line material any way, just to be sure.
Found this Vehicle Standard (Australian Design Rule 35/05 – Commercial Vehicle Brake Systems) 2013
4.1.6. All components and devices in the ‘Brake System’ must meet or exceed at least one appropriate and recognized international, national or association standard, where such standards exist, or the relevant parts thereof. ‘Recognized’ can be taken to include SA, SAE, BS, JIS, DIN, performance and design related ISO standards and UNECE standards.
Dunno if thats of help or hindrance!
Cheers Scott

Almost certainly meant to be 3/16". Some pipes such as reservoir to M/C are 1/4", but if you are going dual you won't have that.

I've got a 75 SWB with brakes from a 78 LWB 1ton going on it. SO really i've got a 78 Lwb I will see if I have a thread gauge that is appropriate.

It is the result of changes of recognised thread standards from BS to Unified, to metric, all during the production of what is essentially the same vehicle. Probably wouold have helped if they had used Unified threads from the start, but while these existed in 1948, hardly anyone in Britain had the tooling to make them.

And for parts that come from third party suppliers, such as brakes, Rover probably had to accept changes when the suppliers decided to make them - which would have been when the big car manufacturers changed! For their own bits, keeping parts backward compatible was a policy pretty much until the end of Series 3, leading to the retention of a few BSF (and many Unified) threads until then.
