ABS and steel brake lines?

I need to extend the front brake line on my 650ABS model in order to install higher bars. I asked around at the dealer today and nobody seemed to know if you can use steel lines with ABS brakes. For their part, they put a call in to Suzuki.

What's the general wisdom from here?

The material doesn't matter. As long as the lengths and fitting are appropriate there's no problem. I expect the lengths and fittings are really what the question is about though.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

The parts guy seemed to think that steel lines "wouldn't have the flex that ABS needed" and even though that doesn't make ANY sense to me, I backed off from challenging him while he went to ask the service manager. He did call Suzuki in my presence and left a message for his contact there. We'll see what they have to say. Haven't heard yet -- the guy obviously took the day off to go riding. :-D

They use steel lines on cars with ABS, and the braking systems put out more pressure than the systems on bikes. Automotive systems put out 1600+psi, so I think you'd be ok with steel lines on the bike.

IIRC, BMWs have braided lines on their ABS. I will definitely be adding braided lines to my ABS 650.

Actually manufactures of ABS systems prefer steel braided or metal tubing for brake lines. The less expansion in the lines the better.

I am going to need a longer brake line to install risers on my 07 ABS as well .. The kits come with two lines, but I appears we only need one?? Am I wrong? Can a person order a single, custom brake line?

Typically, the stock brake has a junction with three shorter lines, one from the master cylinder splitting into two for the calipers, while the SS kits go directly from the master cylinder to the calipers with two longer lines.

Stainless steel lines are a 'required' farkle on XS1100 projects, much like a Madstad bracket is on a Strom. Riders who have installed them report improved brake response, stronger lockup, and shorter stopping distances. Granted, on these bikes you're replacing a 27-year-old rubber brake line, but stainless steel-clad lines *do* flex less than straight rubber. I don't have a source handy, but searching XS11.com should come up with some vendors.

Guess I should have been wearing pants...

Damn. Just found this thread after starting my own. I also need to extend the line to install my risers. It is a single going to the junction block, which then splits to the ABS as well as the two calipers. You only need a single line, but I'm thinking I might as well do all 3 while I'm at it. All 3 are short lines with banjo fittings on both ends. I've looked up Spiegler and it's pretty easy to create custom lines. I just need to find out if the banjos are 10mm or 11.2mm.

Another thing to consider, some ABS systems (aka BMW F650), require you hook them up to the diagnostic module to open the actuator valves. This is the only way to bleed the entire system. I'm still trying to find out if this is the case for the VStrom unit, which I hear are the same as the BMWs.
