    Galfer brake hose question

    I'm planning on replacing the brake hoses on my 2004 1150GS (with ABS) using Galfer brake lines. I previously had a bad experience with Spiegler, so decided to give Galfer a try. Anyway, Galfer has a kit for the 1999 - 2002 1150GS with ABS (kit D265-5). When I asked if the kit would work on the 2004 model they said no and they would have to custom make a kit. So, does anyone know if the brake hoses on the 2004 GS with ABS are different from the 1999 - 2002 models?

    Also, the OEM brake lines on the bike look like rubber. I thought I read somewhere that the 2004 GSA had stainless steel brake lines, but the regular 2004 GS still had rubber lines. Is this correct?

    Any thoughts appreciated.

    Unless the hose cover material is black overlay onto the stainless steel braided hose cover, the stock hoses are most likely fabric reinforced synthetic rubber inner tube and cover. About the cheapest brake hose that will still meet the SAE performance specs. An easy way to tell if the stock hose is not stainless steel braided/Teflon tubed hose is to simply squeeze it. The lower quality hose is much easier to squeeze than the good stuff.

    Speigler, Galfer, Russel, and all the many others who offer stainless steel braided teflon tubed brake hoses all get their hose stock from one of the very few manufacturers that actually make the hose. Parker Hannifin being one of them (who I work for as a field engineer).

    I would never waste one penny on the old stock hoses, unless the goal is to make the bike look stock.

    As to the question on the plumbing difference? Not sure about that one, but all it takes is a fitting or hose end change to make a hose not fit one model versus another, same for year to year. So make sure it is right for your bike, year and model.

    Since most people do not have a hydraulic crimping machine, you might want to consider reusable fittings. They are more expensive then regular fittings, but a doable project for most people without a crimping machine.

    Like Andy said, the R14 PTFE hose only comes from a few manufactures. But, you can get it in commercial thickness (0.030") and aircraft thickness (0.040"). That is the thickness of the inner Teflon lining. If you use aircraft grade, I believe you have to get fittings specific for the hose too. You might be able to get the aircraft grade from Parker. Andy might be able to tell you better.

    One other source is Earl's Speed-Flex brake hoses. They are a shop just for motorcycles. Their web site is hard to use. The fitting are buried (Fuel Systems -> Plumbing -> Hose ends -> Speed-Flex -> Banjo). Their prices are high compared to where I usually buy hydraulic hoses and fittings. But, the quality looks good. Andy might have some better sources since he works for a major supplier. I am just a consumer.

    Cutting the hose cleanly is the hardest part. If you go this direction, we can make some good suggestions.

    You can use this line for fuel and brake lines. I can show you some pictures of some R14 fuel lines and reusable fittings.

    Since I haven't converted my lines yet, I don't know the correct AN size. Andy might know the correct AN size.

    I have a lot of expereince with cutting S/S braided Teflon tubed hose, and all I can say is you're best off leaving to someone with expereince and the right tools. A hose cutting blade is best, and this type of blade has no teeth, and a specific "kerf", plus the hose should be bent as it is cut to get a clean straight cut. If you use any kind of blade with teeth you'll tear the wire apart. An abrasive wheel contaminates the cut and hose so bad it isn't worth trying.

    The hose must be wrapped tightly with nylon reinforced tape in the cut area, or else the S/S braid will spread out and you are screwed for getting the hose end on it.

    I also have a lot of experience with resuable hose ends. Here too, an experienced hand is the best. If the S/S braid splays out on the cut, again, screwed for getting the hose shell onto the braid. And once you start to turn the mandrel in, do not stop part way, turn it to bottom. If you stop, you'll likely NOT get it turning again without damaging the hose.

    Personally, a pre-crimped, specific built assembly is the way to go and worth the money. Don't go cheap on brake hoses, for obvious reason.

    BMW confused things by fitting the '02 R1150GSes with ABS II and I-ABS. Galfer's kit is probably for ABS II. Apparently the GS-Adventure did come with braided stainless hoses, and I suppose you could buy them from BMW. You can also get an aftermarket set from Bobs BMW.

    What problem did you have with Spiegler?

    Spiegler uses aluminum banjo fittings. The banjo fitting on the caliper end of the rear brake hose broke off during installation even though there really wasn't any stress on it. Spiegler replaced it free, but it took nearly a week to get the replacement and the bike (1150RT) was down during that time. I could be wrong, but I believe Galfer uses stainless steel banjo fittings.

    Bit of a hijack here... but since we're talking about braided lines what the heck. One of my bikes has a Spiegler line that was installed due to a rapid rubber line failure and it is about 8 to 10 inches too long. I need to get either a threaded fitting (master cylinder) or banjo (caliper) put on it which will involve cutting the line. Have you done this? It's one long length so shortening at either end will do the trick.

    I don't have or need an expensive crimper for one job so hoping to get a do it yourself fitting and some info on how to properly prepare the line.
