The procedure is very simple, no codes. It takes more time to prep and clean than to actually do the brakes.
A good tip is to use 3 clear tubes (or 6 tubes) at one time on the modulator, to avoid having to move the drain tube as you move from nipple to nipple. It was suggested here in another thread on this forum
- worked very well for me. The servo system is a true one-man job, since the power pump allows easy flushing of the brake circuit, no need for speed bleeders or such.
I just did my '03 RT (servo), '06 GS (servo) and '09 GS (non-servo) and it took me the same amount of time and trouble for each bike. The R1150 and R1200 iABS (servo) systems are the same.
Off-season is the time to do it, as you pull the bodywork for other service as well.
