cutting brake lines

okay so i totally can't get my brake lines off! I used like three different types of vise grip, and i still can't get it off. I've resorted to cutting the lines. I'm thinking about using my dremel tool to cut the lines. I know that there are line cutters but i don't think they will fit. Do you guys think this is a bad idea. i really don't want to botch this cause i need my car by wednesday.

what exactly is your project? are you replacing wheel cylinders, calipers, master?

oops! sorry i forgot to carify. I'm trying to put longer brake lines on the front of my Jeep. I put the lift on and now all that is keeping me from wheeling is the length of my brake lines. I've been trying to get the rubber lines off and the flare nut on the hard brake line both driver and passenger side are rounded off and i can't get them off.
so i'm thinking about cutting the hard line re-flaring. Is there a better way of doing this?

I replaced all the hard lines for about $50 and 2-3 hours work.

Or you can cut the existing back and re-flare it but then it might be too short and it is for sure an awkward place to work.

If you use a saw or cutoff wheel to cut lines, rather than a tubing cutter, you will get fine metal particles in your line and brake fluid. These particles will cause rapid wear and possibly failure once they get into the wheel cylinder or caliper!

Go to Autozone and rent a flaring tool. It'll come with a line cutter. Do not try to use anything but a line cutter. Buy a new male 3/16 brake end (maybe a dollar?) and install it with a new flare. Practice double-flaring on some scrap before trying on your line.

Oh and you need line wrenches to work on brake fittings because they are soft brass. Regular wrenches will round them off right away as you have found out.

Alright, just finished. Took me about 4 hours but I got it done. I just cut the old lines (with a pipe/line cutter) and flared them. What took me the longest was bleeding the brakes. I left out two washers that go between the caliper and the block of the new line. That caused too much pressure I guess, because fluid sprayed out at the joint of the block and the line. Put them back on and I think I'm good. Tested the brakes around he neighborhood and they seemed fine. I'll do some bigger streets tomorrow.
