Need help with brake bleeding!!

[pstoutland]

OK, so I'm reasonably competent mechanically, but I can't manage to bleed the brakes on my 2004 R1150R (abs). I followed what I thought was the correct procedure...replaced fluid in handlebar reservoir...hooked up mityvac to bleed screw...create vacuum...open bleed screw...

 

The problem is fluid came out, but none of the fluid in the reservoir disappeared. After doing the a couple of times, I've realized this is not good. So what am I missing here??!! HELP!

It sounds like you are using the non servo brake bleeding technique to bleed servo assisted brakes.

For a great write up for bleeding servo brakes follow these links here:

They are great write ups by Jamie and Leslie Edmonds

Why didn't I read this first?!! Argh!! In any event, thanks...I'm off to try this.

OK, I've located the reservoir under the seat. Can someone tell me how to get the cap off? It's got a hex-insert on the cap, but it can't be turned due to various obstructions (that appear immovable). Does it snap off? Thx.

The cap is seperate from the vent tube. Try to turn it and you'll see.

I found the attached procedure here a compliment to the BMWSportTouring document.

 

I did mine yesterday with the help of these two references.

 

P.S. I see you are in WC! I'm no expert and am relatively new to the BMW, but PM me if I can help.

Thanks to all! I successfully finished my brake bleeding!
