haybaggerman Posted October 17, 2009 Share Posted October 17, 2009 Hi All I've found a leak in the 8mm copper brake pipe that runs along the hull bottom. Problem is it is right under the transfer box. Anyway, it means I have to join a new piece of pipe in there. Everyone seems to do 8mm copper pipe (actually it isn't imperial but just about 8mm, with 6mm interior diameter) but not the joiners. I've got a small flaring tool which will get in there but not much good if there arn't any fittings. Has anyone used fittings with olives on their brakes? Would that be reliable when you step on the brakes in an emergency? Thanks for any tips or suggested sources of parts. Paul Quote Link to comment Share on other sites More sharing options...

It would be 5/16" I think, definitely not metric for sure. Do not use olives, the pressure is too great and safety is paramount. You can obtain the correct tube nuts and male/male adaptors so should be able to join at a convenient position. Quote Link to comment Share on other sites More sharing options...
Gordon_M Posted October 17, 2009 Share Posted October 17, 2009 Might be more aggro, but I'd suggest binning the whole section and replacing it. You might want to check the other lines too.... Gordon Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted October 17, 2009 Share Posted October 17, 2009 Good advice Gordon. Just remembered renewing a pipe on a Ferret, from master cylinder to servo once, it was about seven feet long. The owner did not want to remove the gearbox.

sirhc Posted October 17, 2009 Share Posted October 17, 2009 I did all of mine with the engine and gearbox in place, it was not easy but is do-able! Quote Link to comment Share on other sites More sharing options...
haybaggerman Posted October 17, 2009 Author Share Posted October 17, 2009 If I could do the whole length then I could get away with using the existing fittings, possibly.......... Quote Link to comment Share on other sites More sharing options...

Gordon I had assumed that I couldn't get the the rear section of pipe with the engine in place, but, I'll have a closer look now Thanks Paul Quote Link to comment Share on other sites More sharing options...

Tony B Posted October 17, 2009 Share Posted October 17, 2009 Use Cupro nickel, a bit more expensive but very ductile and garunteed rot proof. Why go through the grief again? Quote Link to comment Share on other sites More sharing options...
Topdog Posted October 17, 2009 Share Posted October 17, 2009 Ever tried to stop a Ferret going down hill, even with good brakes? Never take a chance, get it sorted with one piece of pipe. Its very easy when removing the gearbox to crush the pipe when the lugs come off the trunnions, so put some wood underneath. Quote Link to comment Share on other sites More sharing options...
protruck Posted October 17, 2009 Share Posted October 17, 2009 If its 5/16 kunifer brake pipe your after try ebay I payed £25 for 25ft. Not to sure if this is a good price but it got the job done. Clive Quote Link to comment Share on other sites More sharing options...

Notto sure if this is a good price but it got the job done. Clive Found that on ebay, I'll give them a call, thanks Clive. Its probably just as well that I've stripped everything out of the interior to get to this leak as I've found a slight oil leak in the transmission as well, I was thinking I would open it up and some instant ghasket would do the trick here? I've just fitted electronic ignition but the brakes gave out immediately so havn't had a chance to even get out of 1st gear yet. Engine sounds alot better though. Is there a scientific reason why as soon as you've fixed one thing, another goes wrong? Paul Quote Link to comment Share on other sites More sharing options...

Tony B Posted October 18, 2009 Share Posted October 18, 2009 Or 'S*8T happens'. Though in braking systems it is almost inevitable. One bit goes and is replaced, then the increased pressure blows something else. Quote Link to comment Share on other sites More sharing options...
oily Posted October 19, 2009 Share Posted October 19, 2009 I had similar problems on my saracen, with brake pipes resembling mutated penny-whistles!, change the whole length, for safety's sake, the main feed from the power-valve/cut-out (equivalent to master cylinder), on a saracen is about 10ft, and weaves in/out under everything under the floor, and I did it without removing engine/box etc, and it worked.....oh I got my pipe and fittings from a local hydraulic hose fitting company, very cheap, they made up the pipes, with fittings, and bent them to shape, ...for a crate of beer. True what is said though...I have to take the gearbox out to replace it now,and to do that, the front armour and engine need removing too, it'll keep me busy for the winter, I suppose!:cry: Quote Link to comment Share on other sites More sharing options...
haybaggerman Posted October 20, 2009 Author Share Posted October 20, 2009 You can't put me off OILY, I still want a saracen I'm going to replace the whole pipe, after looking down past the engine I can just about reach the fitting. Then, drain the transmission, take the end off and re ghasket it, put it all back together, paint everything in sight while it is still in sight, put back all interior fittings after painting them and hey presto, might be able to go for a drive and test the electronic ignition at last. However, an easy job compared to yours I think Cheers Paul Quote Link to comment Share on other sites More sharing options...
oily Posted October 21, 2009 Share Posted October 21, 2009 ....-wasn't trying to put you off saracens!, I think everyone should have one!:-D, They are LOVELY! :cool2: beasts to own and drive about, yes even on the main roads!.....go ahead, get one (while you still can! ....very few around now!):cry: Quote Link to comment Share on other sites More sharing options...

haybaggerman Posted February 16, 2010 Author Share Posted February 16, 2010 At last I've done the brakes, a bit fiddly here and there, in fact a real pain, but all is working, the brakes even bled themselves which suprised me. Now the leak in the transmission box which I'm thinking will be easier. It was just good to get a job done even though its been waiting for 6 months or so, roll on summer:) Cheers Paul Quote Link to comment Share on other sites More sharing options...
