Making a double flare on brake lines
One of the steel brake lines corroded enough that it started to leak.
So I need to replace a section of the line. Somehow it is something that I have never had to do before and do not have the tools. But I looked on the internet and found descriptions of how to do it and lots of discussion on RCM on problems one can have. But what I did not find was anything about how to make the adapter used to make double flares. Have a lathe, should be trivial to make the double flare adapter. In searching I found the Lisle sells the adapters. Naturally none of the autoparts stores carries the Lisle 31370 part, but found a bunch of mail order places that do carry it. Most of them sell the part at discount, but with a big shipping charge. The best total cost I found was Auto Parts 123 selling through Amazon. $2.18 for the part, and $5.23 for the shipping. Note this only is worthwhile if you already have a tool for single flares. After I get the part, I will try to post something so that others can make their own. Dan |

Dan There are variations on the angles, just depends on what type of fitting you have. Around here, Autozone lends those specialty tools out, charge on the card going out the door, refund coming back. Or hit a place that makes the lines up and have an exact replacement made up. NAPA's machine shop does that here. Brakes are something I don't take shortcuts with. Going is great, stopping is better. Stan |

Disaster everytime. I ended up going to a brake specialist who took about 2 minutes to put the pipe into the flaring machine and press a double flare - for the cost of the pipe and fittings. |

Dan Any REAL auto supply will be able to get you the adapter required - possibly not Lisle, but one that will do the job. |

Dan The whole kit from OEM tools was not a lot of money, but making your own is a lot cooler. OK - agreed - BUT - it is going to need to be carefully heat treated too. A lot of the cheap crap out there (read that as Chinese Schlock) is NOT properly heat treated, and the little tit on the anvil breaks off if you look at it wrong. For the cost of a decent kit you couldn't make the anvils for $0.50 an hour. For the cost of a CHEAP kit, make that about $0.05, and for a good kit about $5.00. Jegs sells their "professional" double flair kit for $25.00 (cheap, lowend Chinese) KD sells theirs for about $55 - or $115 for the double/bubble kit. The Snap-on/Bluepoint double flare kit is about $100. The OTC kit is about $40.. |

Owatona Tool (OTC) generally makes/sells pretty decent stuff at a reasonable price, as does KD Tools. Snap-on/Blue-point tends to be significantly higher cost, and slightly better quality - generally. The Harbour Frights of the world, as well as the WallMarts andPep-Boys etc generally sell the cheapest crap they can gdet away with, while Napa is usually closer to (the lower) middle of the road with their "ultra-pro" line |

Making a double flare on brake lines
Automotive and HVAC tubing flares are 45 degrees. Aircraft flares are 37 degrees. The forming tools must be hardened or they gall.
Here is a tip, use reloading case lube (lanolin). It makes the job easier and delivers a better sealing surface. Steve wrote in message ...

A conservative who doesn't like guns doesn't buy one; a liberal gun-hater wants to disarm us all. A gay conservative has sex his own way; a gay liberal requires us all to watch and accept his perversion and have it taught to children. A conservative who is offended by a radio show changes the station; an offended liberal wants it banned, prosecuted and persecuted." Bobby XD9 |
