You have air in the system, it needs bleeding. If you don't know how to do this, take it to a garage/friend/mechanic and get them to do it, and watch them so that you will be able to do it yourself in future

Also check for fluid leaks.

thanks for your kind advise, trophymick.
I also was guessing air bubbling because, this is condition is almost always appering when going down winding slopes; no problem otherwise. The bad condition of the brake fluid was the secongd guess; 'cause I didn't change it since I bought the bike some 3000 km ago. For there is no leaks as far as I can see, it's better be air or bad brake fluid - there wouldn't be much trouble. In fact, I would try to bleed all the fluid out and fill it back again (with dot4 ), then pump all the bubbles away, by myself, as I did before on a Kawa.kle500 ....but, nothing in the back seemed to be the same. so I just walked in some woekshop and asked some mechanic directly this wild question : "where is the bleeding valve of my BMW; it is just the same make like that red one stands there, before your shop?" . And,he politely grunted me to bring it in and not to try doing anything myself. wise enough, so, think I'll do that way. thanks again.
