A very detailed tutorial about bleeding the servo integral ABS brakes. It should work on all R 1150 and R 1200 bikes.
– brake overheats during extensive heavy braking (like going fast on twisties or on the race track)
– brake levers feel spongy
– brake loses power
– brake fluid too old (recomended change every 1 year, to be on the safe side)
– riding for prolonged periods of time in rain or wet environement, like in UK (brake fluid absorbs 2% moisture per year through hoses/brake reservoir; when it reaches 8%, it will overheat)
– problems with old o-rings or brake lines
