Removing hard brake lines from frame bracket Options

[6gsillyca]

I need some help removing the hard brake lines from the frame bracket. I got some SS lines and am trying to take off the stock rubber ones and it just isn't working out...

I took the whole brake assy off (caliper/pads/rotor) and "drained" the fluid out of the line (let it drip into a jar). I got one side off (fronts only, haven't started on rears) but can't seem to get the other off. I have a pair of visegrips clamped onto the bottom under the bracket along the solid part, just under the flare nut, and that seems to be gripping ok.

The part I'm having trouble with is the 10mm nut on top of the bracket. I got the first one off by using another set of visegrips and just muscled it, but the 2nd one keeps rounding. I've been at it for the last 2 hours, broke a wrench trying to get this sob off and have cuts all up my arm from when the nut rounds off and my arm scrapes inside the wheel well... Visegrips don't seem to be working on this side either as they just round the nut off more.

Any help? Is there such a thing as a "3 point" open end wrench. All the ones I have are just 2 points with a curved middle.

You need a good quality line wrench. It slides over the line and grabs the nut from all six sides (only partially on two.)

Hopefully you didn't damage the fittings to the point where a line wrench won't work.

Is a line wrench the same as a flare wrech?

[Coomer]

Yeah. Make sure you get a good quality one. The first one I bought from Autozone would actually bend, rounding off fittings. I now have a fully polished 10mm x 12mm Craftsman one that works well.

if you mess up the fittings, use a set of vice grips to get them off.

I haven't messed up the fittings too bad yet, but the visegrips aren't working for me. Ive tried 3 different styles (needlenose, "flat" grip, and curved grip ones) and they all round the nut more. I'm hoping a line wrench will work better than the grips.

I will be looking for a good wrench for this job. Like I said, I already broke one (sheared the crecent right in half) trying to get this thing off...

use the styled pictured above.
and tighten them suckers down good, they shouldn't strip then

use a torch to heat the fitting as well, that'll help. DO NOT USE PENETRATING OIL! oils will swell and ruin the rubber in the brake system.

Got em all off. Got a nice set of flare's but the nuts were rusted so they ended up stripping anyways...used a pair of visegrips SUPER tight and managed to make do with them. I did use some pb for 1 or 2, but since I was replacing the rubber with ss lines it didn't matter if the rubber swelled...

thanks for the help guys
