The trouble with bleeding both the clutch and front brake is that air usually gets trapped at the master cylinder banjo. The trick is either to loosen the banjo slightly, pull in the lever to eject the air, tighten the banjo then release the lever. This however involves catching the fluid with a rag and is potentially damaging to the paintwork.
Alternatively lean the bike so that the reservoir is higher than the banjo and gently jiggle the lever in and out. The air will return to the reservoir and out of the system, you'll see the bubbles. If you find it easier you can take the master cylinder off the bars to do it.
For the back brake, take the caliper off the bike and hold it so that the nipple is uppermost when you bleed it.
