I did a full brake flush and pad change over the summer when I did a full service, thanks (JVB). Have ridden 3000 miles since with no problem. I have found lots of info about ABS problem with the R1200 series, but could find nothing with the problem of a servo that keeps running. Micro switches seem to be working as the brake lights come on while applying each brake. I cleaned the speed sensors and checked the wiring. I have 33000 miles on the bike.
In the past when I've seen this, it was caused by the rear brake pedal not being able to fully return to disengaged. Suggest checking to be sure the rear brake pedal is working properly.
