You need to pump the air out while not letting any back in when you work the pedal.
It's probably best done as a 2 man job.. though you can get bleed kits that pressurise the master cylinder or have a valve on the end to stop air being drawn into the cylinder when you pump it.
Tools you will need is a 7 or 8mm combination spanner and a bleed tube (clear plastic but with a rubber end).
Anyways.. Loosen the nipple and then do it up again immediately but not tight. Use the ring end of the spanner to avoid rounding it.
Next put the rubber end of the bleed tube on the nipple.. and then using the open end of the spanner (it's easier to work) open the nipple by about half a turn.
At the same time, press the pedal all the way down.
Do up the nipple. Take foot off the pedal, in that order. The closed nipple stops air being drawn in as the pedal goes up.
Repeat as many times as required. You can tell when you're done as there will be no more air bubbles in the fluid (you can see it in the plastic tube). Do it at least until new fluid comes through, even if all the air bubbles stop before then).
So.. open.. pump.. close.. release.
A one man kit stops air coming in so you just pump the pedal after loosening the nipple. The pressure kits are even easier.. just open the nipple.
As you bleed it, make sure the brake fluid level doesn't get too low or air will get in at the top again. Top the level up now and then.
When you did the clutch, it'd be worth doing the brakes now that you have all the stuff out.
