    Say, has anyone got a convenient diagram of the nipple bleeding order for the servo unit? I've seen those european videos where the guy points out which is which and can go back and do screen caps with notes, but would prefer not to re-invent the wheel if it is already around somewhere. Thanks!

    I also do the same on the R1150 servo bikes.

    Woah! :eek1 Only a single point for front and a single point for rear now? This doesn't leave crappy old fluid in there? :scratch

    Thanks for the spiffy pic! :thumb

    From what I can tell this is not an issue. You can do the others if you like, look in the HOW to see the sequence, but I have done it both ways doing the two only first, and then the other four. I have never seen any idnication that the other four had trapped dirty fluid in them.

    Ok, thanks. The HOW seems to detail the older one, not the hexhead one, though, right?

    True, but they are essentially the same for maintenance/service purposses.

    It is not the old fluid that causes issues, it is the depletion of the corrosion protective additives. There are PH buffers and such. the fluid mixes. so the fresh additives get mixed in and protect. Annual changes are kind of overkill, but you are sure to be protected and the ABS unit is expensive.

    Pragmatists will do as recommended, using brand name Dot4, perfectionists will do them all using only BMW fluid Both will have the same results.

    So, as recommended, do only the two main control circuits and you are fine.:evil

    Hi There,

    I guess this will be stupid question.
    In the RepRom for GS 2010 is mentioned only bleeding for front and rear breaks. Nothing about ABS unit. Is that means that non servo units does not need it?

    I agreed with JBV, going through all the circuits, there's a point of diminishing returns. Check the color of your fresh brake fluid before and after the flush....The color of my old fluid was a light tea color, and the new fluid was crystal clear. This at least gives you some form of qualitative analysis....I flushed the servos in two circuits method as per JBV's video....After bleeding the system...the fluid in my system was almost the same color as the fluid in the new bottle...in other words most of the old fluid was removed by the two circuits method...

    If your doing it yourself...I might also add making sure your gas tank is almost empty...My tank was full!....lesson learned..lol!

    Also may sure you get the special funnel from the Beemer Boneyard too...

    It isn't really necessary every time. I actually know that most never bleed the ABS unit on the newer bikes, and it really isn't an issue. On the 2007 and newer bikes there is no need. However, if you have the GS911 it is nice to cycle the ABS for bleeding, but again, not really necessary.

    Perhaps another stupid question but i bow to those who know,
    I took out a 2010 for a test ride Saturday, couple of observations
    It's got only 7000 km
    The front brake reservoir had a cloudy look (possibly water in the system)
    When I started it up in neutral before moving the bike the brake caution light was flashing (circle with brake symbol inside)

    I've got a hold on the bike but I don't want to find out the abs is bagged at a 2k repair due to lack of Maintenance :eek1

    Thoughts from the gurus would be appreciated, anything I need to check or ask about? I did tell the sales rep the fluid was bad.

    thanks guys..

    That is the bike saying your ABS hasn't completed its initialization test. It won't complete until you are moving about 3-6 MPH. I'd STRONGLY suggest you download the riders manual for the bike and read it before buying so you know what is normal and what isn't. Riders manuals are available from BMW at this link.

    That "cloudiness" you see is likely the foam installed in the reservoir. If the brakes are working normally, and you have no fault lights, you are likely fine. I would ensure you have service records, but on a 2010 it is pretty unlikely that your ABS has an issue or dirty fluid, especially at such low miles.

    Thanks so much Jim, I'm new to BMW and there's a lot of "I don't knows" I'll download and read the owners manual as well to get my bearings.

    On the up side when I took it the bike felt like a kid again, it was a lot of fun to drive, can't wait to ink the deal. :deal

    Thank you Jim,
    Valuable hint as always. Will consider about GS911.
