flyingbrick Posted February 8, 2015 Share Posted February 8, 2015 Hi all. Need to make new front brake hard lines and extend my rear hard line on the holden ute. Bending the tube and forming the flares is no problem but I have zero idea what to order or ask for fittings wise. Can anyone help? Quote Link to comment Share on other sites More sharing options...
downtrail Posted February 8, 2015 Share Posted February 8, 2015 3/16 line is normally what youll have get bundi steel is crap to work with.

flyingbrick Posted February 8, 2015 Author Share Posted February 8, 2015 Thanks Mjrstar. So.. Do I need double or single flares on the ends of these lines? (They will be mating up to the master cylinder and factory rubber hoses) Quote Link to comment Share on other sites More sharing options...
Nominal Posted February 8, 2015 Share Posted February 8, 2015 Brake lines are normally double flared. Quote Link to comment Share on other sites More sharing options...
downtrail Posted February 8, 2015 Share Posted February 8, 2015 Look into the ports if you see a small tapered cone sticking up then double if its a tapered hole then single. 1 Quote Link to comment Share on other sites More sharing options...
cletus Posted February 8, 2015 Share Posted February 8, 2015 double flare them. copper nickel is a lot easier to work with than steel, can bend it easily by hand not straight copper 2 Quote Link to comment Share on other sites More sharing options...
cletus Posted February 8, 2015 Share Posted February 8, 2015 also you can re use your original end fittings ("tube nuts") if they are in good order 1 Quote Link to comment Share on other sites More sharing options...
cletus Posted February 8, 2015 Share Posted February 8, 2015 also in a holde with a chev, if its got headers you may be better to put the brake lines on front of the crossmember rather than the original position otherwise they get too close to the headers usually 3/3 1 Quote Link to comment Share on other sites More sharing options...
kempy Posted February 8, 2015 Share Posted February 8, 2015 Any reason for not using straight copper? I'm curious as I will need to do the caravan lines soon. 1 Quote Link to comment Share on other sites More sharing options...
Bling Posted February 8, 2015 Share Posted February 8, 2015 Not allowed, something to do with it becoming brittle / fatigued, from memory.

Mof Posted February 8, 2015 Share Posted February 8, 2015 Copper-nickel is definitely the way to go, so easy to shape by hand, and flare But it is kinda soft and could squash with a whack from a rock or something But personally I definitely would, and have used it rather than steel 1 Quote Link to comment Share on other sites More sharing options...
kempy Posted February 8, 2015 Share Posted February 8, 2015 Thanks for the heads up, I had a roll of copper pipe that I was going to install. Quote Link to comment Share on other sites More sharing options...
grunta Posted February 8, 2015 Share Posted February 8, 2015 cu-ni tube is just so much easyer to use than steel tube ! bend by hand easy and hand roll around bar for pig tails! 1 Quote Link to comment Share on other sites More sharing options...
tortron Posted February 11, 2015 Share Posted February 11, 2015 Get a good flare kit i like the mechpro? One i think. Comes in a red hard case anyways. Done a few car sets with it and am happy with the double flares a wee bender is nice, but not necessary. Looks more pro tho Have used both bundy and steel. Steel isnt that much more work and imo give a nicer finished product as its less likely to get a wiggle in it w re double or single flare double is used because a single flare thins the metal and can result in fatigue and cracking/leaking Quote Link to comment Share on other sites More sharing options...
