With bulletin BMW #34 002 06 (019) of April 2006 they changed required interval for flushing brakes and also method for bleeding the Control Circuits (the tougher process of bleeding
I did a lot of searching and looked at forums and found 2 very good papers.
A) BMW Integral ABS Systems Flushing and Bleeding 101 from Dana Hager and Charles Gilman and
B) K1200RS/GT Brake bleeding from Gary Hollinger
1) On paper A) at the beginning it talks about Right Front Caliper/Clutch Filler adapter. The picture shows a Brembo caliper which I believe is used in ABS 2 systems (not the integral) so the bleeding in those systems is different and easier? The newer ABS III Integral system have the BMW Calipers (as he shows later in his paper)
2) Paper A) shows different method to bleed the Front and rear WHEEL CIRCUIT than Paper B) . I guess Paper A) From Hager and Gilman is for another model or post 2005 year of K1200?
3) if we follow Gary's paper we would have to modify his front and rear CONTROL Circuit method by only flushing what he shows as F3 Front Control Circuit and R3 rear control Circuit.
Just wanting to double check my assumptions before starting the process
