I've read the great diy on brake fluid replacement and bleeding done on RTs from 2007 on (posted in 2009). My concern is that I've had to replace the upper front brake line on my 2012 R1200R so that I now have a huge air bubble in the front integrated ABS system. I'd like to just replace fluid and bleed in the traditional way as described in the excellent diy of several years ago, but I'm concerned that using this traditional method may screw up my ABS controller by getting air trapped in the controller that could be nasty to remove. Anybody had experience with this or do I have to roll up my sleeves, take the gas tank off and bleed at the controller?
