Are Rover brake lines double flared or single?

Hi everyone,

My son and I are making excellent progress on his series II - we hope to have it on the road in a couple of weeks. We ordered a wrong brake line but have the correct end available on another line. Question: is that what they call a double flare on the tubing? It almost looks like the originals have some type of bubble flare? Maybe the second part of flare was just not compressed at the factory? I am hoping I can just cut the end, slide on the right rover fitting and double flare it? Does that sound right?

Thanks in advance for your valuable reply!

I am curious about this as well. I have replaced all the lines in my Series 1 and the two rear lines leaked and could not be tightened enough. I finally realized that the fitting on the end of the new line needed to be reduced in diameter for about 1/8 inch so it would set the flare or bubble into the seat area and make a seal. After I ground down the fitting I experimented with both bubble and flare and they both sealed. The old linesI took off where flared but they were likely not original.

Your 1970 2A uses a DIN flare. Also known as a bubble flare. It looks like a mushroom from the side. This for all 3/16ths brake line, some of the clutch line, depending on whether the clutch master has the adapter or not. The clutch line may be 1/4". It may also be metric fittings but probably not for that year.
All brake line nuts are Lucas/Girling 3/8-24 threads available here or at fedhillusa.com. Fedhill will rent you the tool that makes lovely beautiful fabulous flares for $25 a week. Or you can buy it, but it's not a cheapo.
Do not cut corners or make splices in your brake lines if you can avoid it. This is an important safety item and is truly a life and death matter. Fudge anything else but the brakes. Spend the money for top quality parts and install them carefully and correctly.

One of my favorite documents from the Federal Hill (www.fedhillusa.com) website is their flare identification chart: http://www.fedhillusa.com/webnuts/common%20flares6.pdf

Both the first post and the second post in this thread are addressed by the chart.

Thanks for the tips. We just saw some bubble flares being made on youtube - looks like something we can handle.

We really appreciate all of your help!
