Brake line flare question?

Reading the instructions in R&PS dual cylinder brake upgrade it says to double flare the existing brake lines. Well, I got started disconnecting things & when I was disconnecting the brake lines at the junction, I got to looking at the T fitting they sent along to connect a brake light switch & was wondering if that needed a double flare as well, so I called R&P & they told me that they only put a single flare on the ones in the shop??? Even on the cylinder itself??? :? Can anybody straighten me out here? I'm sure that at one time I knew the answer myself, but that was probably a good thirty years ago....

 

Which brake tubing is this? You need double flares on brake lines everywhere. The only place I've heard of using single flares is on refrigeration.

 

Double flare. I happen to know R&P double flares them. You probably spoke to Paul and he was probably tired. He's been holding down the fort there by himself and he's in his early 70's. he doesn't do the flaring either

Follow the instructions, double flares.

 

Thanks guys...as far as ALL brake lines being double flare...Why do they say the existing lines need to be modified? Looking at my existing lines at the junction box/splitter, they don't appear to be double flare...

 

Tom,
Look close, they will be double flare.
I think I can help you this time, I have a good tool for double flare brake lines. Give me a PM for some free time this weekend.

Thanks Don but I think I have it covered...I should be able to get it done this morning...I got confused on flare types a couple youtube videos got me straightened out. Old age is starting to take its toll...

 

just a thought . something I learned years ago about doing brake lines . after you cut tubing with tubing cutter , take a flat file and flatten end of tube , then debur inside and outside of tubing , before putting in flaring tool , and spray everything with WD40 , makes a perfect double flair everytime

 

Those are good suggestions, although I would worry about contaminating the brake fluid with WD-40. I use a little brake fluid for lubrication. Does make things go easier.

However, I would suggest you use the Nicopp or Cunifer line if you can. The copper alloy lines are both easy to bend and easier to flare than mild steel.
