R1150r rockster brake fluid flush

Hello,

I've got an 04 rockster. I've been performing lots of maintenance on the bike, as it is used. So far, I've done: gearbox oil, final drive oil, oil/filter, air filter, and soon plugs. I've read that the servo assisted braking system requires special attention. Right now, all feels well, but I'd like to know if there is a "step by step" guide to flushing the system. It's just something I'd like to get a handle on, because I know I'm going to have this bike for years

Any info is much appreciated,

Thanks!
