    So I figure it's time to give my '06 hexhead a full break job before summer (now that I have a wife on the pillion to keep safe). Doing some research and reading the excellent BMW Integral ABS Systems Flushing and Bleeding 101 article found on this site (big thanks to those who wrote it), I decided to build my own filling adapter as shown in the article.

    Unfortunately, doing some research part # 34 51 7 677 998 (the part that adapts the funnel to the ABS module), the local dealer shows that none are in stock in NA or Europe. Checking some other sites, they show them in stock, but are now for sale for $53! That's more than double the original $23 they cost. I think that is ridiculous for a piece of aluminum not much bigger than a couple quarters.

    Does anybody here have their filling adapter and a caliper handy and is willing to share the dimensions? It should take less than an hour to crank one out on the lathe. That $53 will be better saved towards a new helmet.

    Thanks.

    Here's the real deal. Cost me way more than I wanted to spend. And that was back in 2002. Spend the few dollars,buy the "one piece plastic one" from Beemer Bone Yard and be done.

    +1. The one I got from Beemer Boneyard works great.

    Interesting...what's the part with the threads? Source?

    I got 4 of these 100 cc syringes as SAMPLES a couple years back.
    Couldn't find the mating piece that you somehow found.

    As a result, ended up sending $34.95 to BBY for theirs.

    Let me know. Thanks.

    I got it from a buddy in England, FREE! he buys wrecks and parts them out. Told him what I was trying to build and the cap off an ABS pump showed up in the mail a few days later. :deal

    I have the threaded part (shown in microfiche shot above) - it was not cheap.

    There is a thread here where an inmate used a simple rubber stopper, as you write. This is a brilliant idea; I'd use the cork if I had to do it again.


    EDIT: I did find that thread; more info and picture here:

    I found one here:
    http://www.caplugs.com/productdetails.aspx?id=1000021&itemno=BSP+SERIES

    Just have to figure out the correct threads. And...how NOT to buy a minimum of 500!:clap

    BTW...if we can figure this out...GLAD TO SHARE 3 of the syringes with other inmates...for use with ABS only!
    Probably against prison rulz...but since I'm an ADV lifer...who cares!:rofl:rofl:rofl

    If you buy 500, I'll take one.

    Perhaps you can get a few others and make that minimum order.

    I bought the funnel with the funnel with the rubber end from the States. It really makes things easy now when changing the brake fluid :)

    If I was to know how it looks and how it works before purchasing it, I would have made myself a conic rubber cap and put a funnel in there and not pay the 70$ it cost me for buying the tool.

    On the other side, I like having the nice transparent tool, but would definitely not pay 70$ again for it :D

    Just to add a different perspective to the bleed procedure, the funnel is wonderful but not necessary. The bleeding can be accomplished quite well without the tool, it adds less than 5 minutes to the process but you need to pay attention to the amount of fluid being purged and err on the side of caution.

    The funnel is really nice but not a requirement, just saying.

    Kind of like , you could use pliers to get that 10mm nut off, just be careful :freaky
    from what I have read (no first had experience thank God) its a real bad thing if you introduce air into that system.:eek1

    1. Air will not get into the system unless it is run bone dry. 2. There is a factory vent to atmosphere coming out of both caps, it is not a sealed system. 3. There is a BMW service bulletin increasing the bleed frequency from 1 year to 2 years on models with Stahlflex lines. 4. There is a BMW service bulletin stating it is only necessary to bleed 2 nipples on the ABS unit, not all. 5. If it is run dry it is no big deal, fill it up and bleed the air out, pretty simple.

    It is not the same as using a pair of pliers on a 10mm nut. Do you use a "funnel and cap" on the master cylinders or do you fill it up, put the cap back on and bleed? Same exact thing here.

    "from what I have read (no first had experience thank God) its a real bad thing if you introduce air into that system"

    I am sure you have read that, I am sure you thank God you have not experienced it, but the last part of the sentence is not accurate.


    I stated the funnel was wonderful but not necessary, that is all. These units are very forgiving and reliable. If you do the reaearch on these units versus the others you may very well find the failure rate to be no more and probably less than the systems before and after it.

    Be safe out there.

    OK, I found the thread I mentioned ( <- click the link), showing a rubber stopper instead of the screw-in cap for the reservoir-fill funnel.
    Picture below is from that thread.

    If you buy the caps labeled 2 and just put a piece of tubing from the cap tubing barb into a bottle of brake fluid located slightly lower than the ABS reservoir you don't need a funnel. As you draw down the fluid, the vacuum pulls more fluid into the reservoir from your bottle of new brake fluid. You could even use the caps that are on the bike, but it is scary to remove the tubing from them because they are plastic and the fit is very tight. This is the way I have bled the brakes several times on my 05 GS. As I recall the caps are kind of expensive and you have to buy two of them.
