Maybe it is the flux?? I just bought the cheap burnzomatic flux, because my local linweld didn't have the harris flux. So far i am having better luck just using brazing rod. Sould i go for the harris flux? |

I've looked into this, but it seems in the UK our automotive brake line is copper or cupro-nickel whatever that is!). Am I right in thinking US brake line is steel and 1/4"?

Great thread! Thanks to the info here, I think I'm all set to try brazing. I have the OX2550KC Cutting, Welding and Brazing Torch Kit and I have some brake line, steel rod, and aluminum tube. Now my question, I have some brazing rods that are coated, does this coating replace flux or do we still need flux paste? |

Yes the white or blue coating is the flux, works well. For more info on brazing: http://www.handyharmancanada.com/The...Book/bbook.htm |

You can solder zinc, so maybe you can solder zinc coated brake lines. If you get high quality solder like Bridgit, it should make fairly solid connections.

If for some strange reason you grab a spot you just brazed before it cooled, run to the kitchen as fast as possible and get an ice cube from the freezer and hold it between the fingers you just used to grab the hot joint with till it's completely melted.. It will remove the heat that causes your finger tips to blister.  |

The heatgun won't be hot enough. You really need a gas torch and some 6mm O/D solid rod or tube.

I just created a .pdf file with all of the information on this thread that I found useful - or could find useful later. It's probably easier than going through all seven (?) pages. If anyone else wants to read it, then please tell me how to post a .pdf I'll post it or post a link to it. Photobucket doesn't allow .pdf files to be uploaded - where can I put a .pdf file so others can see it? Thanks, AR |

Adding to the supply list, I'd recommend the following: Hand files - small round, triangle files (Dremel's are great but there's always something more/better/easier you can do by hand) Metal clamps - remove the rubber tips:  One or more of these:  Last edited by Axial Rose; 09-07-2009 at 01:08 PM. |

Sorry if this has already been asked, but while brazing do you keep the two rods that you want to braze slightly apart so the flux and silver can get through to the other side or do you just let them touch?

I have never had any luck using the above items, I mainly use blue painters tape to hold pieces in place- quick and simple. p!nK | |
