Post subject: | Copper brake pipes |
Does anyone know if these are copper brake lines or kunifer? If they're copper I suppose they're illegal right? Thanks http://www.minispares.com/product/Class ... |Back%20to |

They are copper, it says so in the sales blurb. I would be tempted to use it for the hydro lines (Minispares sells a 4 piece kit with 2 joiner sockets), but not brake lines... |

Is it possible some of these copper brake line kits are copper plated steel to stave off corrosion? |

Copper tube is commonly used for brake piping in UK. If you want the best brake pipe use cupro-nickel, available here. It won't rust and is way stronger than copper. The problem with copper tube is it work hardens with age or movement, gets brittle then can break. |

is it illegal? Seems strange that the UK would allow it! |

The UK covers its roads with salt, they would all die if they used steel brake lines. They commonly use copper, cupro nickel or cunifer brake lines, mainly for the corrosion resistance. Tim |

OK, so I'm looking at getting some new brake lines and saw that some UK companies do copper and some do Cunifer (cupro-nickel) 'drmini in aust' wrote: If you want the best brake pipe use cupro-nickel, available here. It won't rust and is way stronger than copper.
This brings me to a few questions; 1: Is it Legal? (ADRs) 2: Does it work Harden? |

(ADRs) 2: Does it work Harden? It is legal providing it meets adrs or equivalent ISO, SAE etc. It does work harden but not in anyway like copper. Its also very easy to work with. It doesn't need a heavy duty flare-ing tool like steel does. |

Just go to your local enzed or similar hose shop and grab a roll of brake line. Make them yourself it is extremely easy to do. If you dont have a double flare tool or pipe cutter just take the old ones and get them to bend them up and put the ends on. |

Tim that makes sense - I did wonder my mate inspected a dodgy compliance/roadworthy on a UK import Maserati, looking underneath it when it was brought in and all of the brake lines were completely rusted (among lots of other nasties) |

Remembering around 300-320psi (on first pump up) ![]() Yes no problem. You can also get a pipe kit in UK with plastic line instead. Back in 1970 I used to plumb the brake lines on Formula Vees using 1/8" nylon line, and crimped brass end fittings. No rubber hoses. The nylon was rated for 2,500psi. |
