i am new to gwoa. I recently purchased a 1983 lwb with some missing parts and am in the process of a frame off restoration. i am currently in the process reassembling the frame and would like to begin replacing missing brake lines. My problem is that that almost all of the steel brake lines are missing or completely rusted out, as well as the hard lines for 4wd. So i am having a difficult time figuring out what lines i need to puchase as well as where they route to. My wagen has the dual circuit brake system as well and this only adds to my confusion. So i guess my question is what would be my best source for a diagram or pictures indicating brake hose plumbing. I have unsuccessfully purchased a few w460 repair manuals but neither have in depth brake line diagrams. thanks

Re: Brake line diagram

Want to know if you have a Left hand drive or Right? There is a small layout difference.

The brake pipes are usually copper pipes not steel. Fuel lines will be steel or similar. I have seen these on Australian spec vehicles; not necessarily G-Wagens.

Would you also answer how many brake feeds are there to the front caliper? These could be two or three feeds.

Re: Brake line diagram

Virtually all car manufacturers use steel brake lines that are either painted or plated steel

No car manufacturer ever uses copper as it is too soft for long term use

Cars with copper brake pipes have been replaced at a garage or by the owner of the vehicle


They sell copper brake line that is very easy to bend into the desired shape but i never liked people using it. It is too soft and can get damaged too easy


As said cupro nickel is much more durable and easier to form than steel. It is very good in my opinion

A little note to everyone . Years ago i never had any issues with cunifer, cupro nickel brake pipe. We only bought good quality pipe


Since i have seen many rolls and the bore is not in the centre when it has been formed. Meaning a thicker wall on one side of the pipe. Yes i know no sides to a circle but you get the point

All the pipe is pressure tested and will be fine but if you try to form it it does not look 100% perfect 


I always select good rolls of pipe now, trust me most are poor so check and life will be much easier with a perfect flared joint

How sad am i. On my vehicles that i restore or want original i buy steel line and bend it exactly like original and spray it green like most are
 from factory. SAD i know lol but it looks ace

Re: Brake line diagram

I have done a lot of research on this an have to disagree. Copper-Nickel has a longer life than steel pipe and has been used by Volvo for many years to combat Scandinavian winters. It must be copper-nickel, not the plain copper variety. It does have a lower burst pressure than steel, but tests have shown that steel after a year or two develops crevice corrosion which reduces its strength below that of copper-nickel pipe. Car companies use steel pipe only because its cheap. But, yes you need to find a supplier of good quality copper-nickel. Otherwise, go for stainless-steel.


There is some good information here, albeit from the Copper Development Association:

Re: Brake line diagram

Hi Arnie

Read my post again. !!

Copper is just copper

cupro nickel is copper and nickel, also called cunifer. Thats what some volvos used to use. Cupro nickel or cunifer is the same thing

I say that copper pipe is never fitted to any production car. Copper pipe

Later i say cunifer or copper nickel is best (its the same thing )

Yes they sell pure copper pipe to replace brake lines with no nickel added for strength which i said no cars i have ever seen use copper alone

I stated copper nickel is good copper alone is not

I agree on stainless steel but its hard to form and bend like original for most people

Please advise me if i am wrong. I can take it    if its correct

Re: Brake line diagram

Hello,

Yes, sorry, I must have indeed misread your message on plain copper vs  copper-nickel / CuNiFer / cupro-nickell.

Re: Brake line diagram

No Problem

I have seen many copper brake pipes on cars which garages or owners have fitted

They soon go green and scabby and if you have to undo the union nut the pipe just twists off

How much is a roll of stainless brake line????. I have searched and it says stainless but is just plated steel when you read the full advert
