Double flares? The pipe is pre flared. For some reason, I don't think it is going to work.. but I know I will find out.

Yes, typically the replacement tube sections have double flares on both ends, but you will need to double flare the tubes already on the car too. That'* how it is connected together: a union and double flares. The ends going to and from the proportioner valve are bubble flares though. This is why I had such a difficult time finding the right tube.

Now that I am officially confused.. I don't know. I am going to try what i've got. For some reason I have a bad feeling it isn't going to work as is. I will make sure I have the right diameter tubing, then see if I am going to be even close to making it fit. Then, bend everything up, and go from there. I just got back from chuch, so i'll be heading out in 30 min or so and go from there.

after working a little.. I ran into some trouble. The line I purchased had a different flare, this is where I think the double flare thing arised. Plus my line is slightly larger in diameter, however it still would have worked, if the flare was ok, which it wasn't. I need to get a double flarer [sp?], along with just some straight line. I will be getting that stuff tomorrow, and for now, I will let her sit and leak. I had to cut the line going from the prop valve, because I couldn't get that damn thing off with a cresent wrench. I couldn't find my 12mm socket, so I really couldn't get that sucker off. Other than that, it was smooth sailing, everything is going ok so far, the line snapped upon removal, but its all intact other than that, so I can use it to make my bends. I proposing that all will be well. We'll just have to wait and see!

The left tube has a double flare, the right has a bubble flare. The two are NOT INTERCHANGABLE. Brake fluid is under high pressure. If the ends are not done correctly, you will loose brake fluid.

No fluid=no brakes=no good

This is something you should not do half-assed. I can't stress it enough. Without properly working brakes, you are putting yourself at a very high risk of endangering yourself and others.

that'* what i've got! The flare on the left is the tube i've got, the flare on the right is what my old lines have. Don't worry bud, i've driven the car without brake fluid.. about 140 miles actually.. if I had to make a stop fast.. i'd been screwed. Oh yeah, no brake fluid = no power brakes.. you still have brakes.. just not very good ones. Don't do this, just fix your damn leak everyone.. I am stupid.. and scare the crap out of everyone. Don't be like me! I can get a bubble flarer at AZ, right? Not the line btw, but the actual tool to do bubble flares.

Actually your brakes work with hydraulics, so no fluid NO brakes. And what you do have for brakes is NOTHING to speak of. I know I blew a line on my Bonneville. You had to go pretty slow and almost hold both feet to the floor and hope it stooped ( just the length of time it took me to drive it from the parking spot onto the trailer to haul it home when I moved.

trust me bud, my fluid was EMPTY.. it ate 2 bottles of brake fluid.. and I still drove it 140 miles. I had a very firm pedal.. and it wasn't comforting to have the car like that, but my ebrake works.. so I knew if I was in a jam, i'd be able to use that.
