Braided Stainless Steel Lines
I'm planning to replace the stock rubber-sleeved braided lines with exposed stainless steel braided lines. Has anyone had any experience with this modification? It looks pretty straight forward but there's usually a trick to everything!

I haven't done my bonnie yet - I do have a replacement front line, because I put risers on the bike, and I think the brake line is a little too tight - I worry about fatigue of the brake line at the joint.
Anyway, I have replaced brake lines on a number of other bikes with goodridge braided stainless lines. There really wasn't anything to it - be mindful of your torque values when tightening the banjo bolts, and once the brakes are properly bled check all joints for leaks.
Obviously, make sure you purge as much brake fluid out of the system as you can before disconnecting the old line, and I don't recommend reusing the old crush washers.
Other than that, when ordering the lines try and get fittings angled and rotated to the same relative position as the existing brake line - I think the ones you pictured are the spieglers, which have rotateable fittings. I have one of these for my bike, but I haven't fitted it yet.
I would be surprised if you see any improvement in braking by the way - just be prepared for that. It was different with the old rubber hoses that bike manufacturers used to use - those things would get all spongy feeling, and replacing them with braided lines was night and day difference.
Cheers

Big Difference
I got the stainless lines from NB along with EBC pads. Did both front and back.
It made a huge difference. Do it.

That surpises me a bit, but hey if you saw a difference that's cool - I think I'll hurry up and fit the line I have hanging around based on that (also from newbonneville). Think I'll get some of those EBC pads too, I could use some extra braking power.

I haven't done it on my Scrambler yet,but when I did it on my RD-350,it made a noticeable difference. Mostly in initial bite.
You probably already know this,but cover your tank,and everything else you can,to make sure you don't drip any fluid on your paint.I dripped some on the forks on my RD,and when I wiped it off,the paint came with it.
Cheers!

Make sure you sue stainless banjos though. Ally ones will/can crack and leak
Having cracked and leaking brakes can change the colour of a few things, the paint and the colour of your underware.

This is confusing. The washers need to be made of aluminum or copper, maybe even brass so that they will seal. Stainless will not compress - its too hard.

The banjos are the round things on the end of the line that look like banjos not the crush washers.

Silly me. I'm functioning without caffeine and it shows.

Yes I've done it. Got them from Bella Corse as well as a 6 pot front caliper. Get a good one person brake kit. The BC kit came with new crush washers and identical lengths to stock. Torque according to specs and then bleed. Nothing much to it. Since I did the front caliper too, it's hard to say how much of a diff it makes, but I'll never have to replace the brake lines, so that's a plus.
