I thought autozone did tool rentals and last I checked they had both flare tools.

Check there first.

Isn't a single flare and a bubble flare the same thing? When making a double flare, the first step or 'flare' made is a bubble flare. One more flare makes the double and prevents cracking that could result from a single, correct?

In a single flare, you are just bending the cut edge outward.
In the double, you first flare it inwards, then when you go to flare it out, the inward edge bends down into the line and the next lower section gets bent outwards.

I NEED to fix this section of line today. I don't get paid for another two weeks and though money is very tight this week I can't keep refilling with brake fluid every other day because that will probably be even more expensive than if I just fixed it.

Since money is very tight should I be able to just go to a store and get pre-flared lines with the nuts needed?

When I replace this section...I'm still going to end up having to flare something though right? (If so I'll need more $ for tool rental) I hope to fix this for less than $25, but I doubt that is possible...

Ok, I went to Advance Auto. Got a 60" piece of brake line, tube cutter, bending tool, got home and jacked the car up. I spent an hour trying to inspect everything and basically scope things out. I couldn't even get the fitting off the original brake lines they were so rusted tight. I started to round it off and I stopped I don't have any more PB but I don't think that will help anyway. I'm screwed now. Looks like I'll be blowing some money on having someone repair it. Which won't be for 2 more weeks...

BTW, this is the worst section possible to replace. The rear passenger side where all the crazy bends start at the side of the car and runs to the wheel. Everything'* pretty nasty and wet. At least a good 14" is horribly rusted. The 60" I have is probably 12" shorter than what I would need to fit from the original fitting points, since I'd have to bend it in many places. It would have been nice not to have to do any flaring.

I had one question though...the guy at Advance said I could use the brass compression unions to join lines. He said (and so did the packaging) that it shouldn't be used on brake lines, but that it works. They didn't have my size anyway. Would this union be ok to use??
