Having looked at a few threads online,

1. Some just flush out and refill/bleed with the new fresh fluid of whatever kind they're changing to... The theory being "only put brake fluids in your system", it's enough to flush old fluid and water droplets out.
2. A few flush with alcohol and blow it out with compressed air before filling and bleeding with fresh fluid.. The theory being "better not have ANY water or contaminants in there so clean it out first" in case you reach a boiling point.

I don't need an extreme level of performance and I monitor my fluids, I'll go with option 1.
