My rear steel brake line is shot. I was looking on advance autos site and they have kits that include fittings and a roll of copper tubing. Anyone ever use this? I would like the reassurance of the copper not rusting but I'm not completely sold on the idea of it holding up to the pressures and heat of the brake system.

 

Last I heard copper is not legal to use for brake lines. If you want it to not rust, stainless lines are available.

 

Copper brake line has been a big no-go since, well forever. There is a new nickle-copper line available that is probably confusing everybody.

 

Yes copper nickle ferrite i think. I work for advance. It is dedicated brake line.

 

i agree that the OP is probably talking about the nickle/copper alloy lines.
that is all i have been using for about ten years now. steel lines only last about a year. the alloy lines are all still in use.

 

Yeah it is brand Nicopp and the description says nickel copper line. Sounds like I'm gonna give it a try. Thanks everyone.

 

I used nickel copper to re-plumb my 64 F100 and would not use anything else. The cost is 2x steel but you can get 25 foot coils for $30 an Amazon. Besides not rusting, you can make nice bends by hand (or with soup and tomato paste cans) and tight 90 degree kink free bends with a 3 roller hand bender. It flares easy it you lubricate the flares with brake fluid.

 

Anyone split some rubber hose to space the line off of the frame in spots it may rub? A softer material that may rub through was my only concern and i may just be overly cautious.

 

all the time. but i used to do that with steel lines too.
