Had the dreaded brake failure light stay on the other day on my 2008 gs mu 
no gs911 so started a process of elimination ,I'd had the front wheel out a week before the warning came up and this was the first time i'd used the bike for 3 weeks so started to check every thing was back in ok, not a lot you can do wrong really though , what i did find was the gap from the front abs sensor tothe ring was 1.2 mm!! limit is 0.2 - 0.7 mm, buggered around with front wheel instalation and found no way to change the gap 
Next i checked rear sensor ,all ok no filings at all and speedo was working anyway so was a long shot really , also checked the rear light connections even tho its led ,but again no corrosion , i'd already charged the battery even though it's a fairly new 16 AH motobatt, i'd read that low battery voltage can cause issues .
I was starting to get a bit desperate now so disconnected battery to no avail inbetween all these checks kept riding the bike helmetless up and down the cul- de - sac praying the warning light would dissappear, after that i decided to unplug the front abs sensor up near the tank as i was leaning towards a duff sensor (hopefully not the abs unit !!) no corrosion there either .
THEN EUREKA!!! found a few threads mentioning stuck abs pump brushes !! the bike had stood for 3 weeks SO out came a long tyre leave and a hammer, few sharp taps either side ,back on with the ignition , AND brake failure light now flashing !!! it wasn't doing that before !! quick blast up the cul- de -sac again and it's only bloody worked !!!!!! neighbours thought i was mental doing fist pumps in the road
)) so thanks a million to whoever came up with that idea i was starting to sweat pound signs what with the bike insurance due in 2 weeks as well . so if in doubt give it a clout
