You need to use some new brake fluid (from a sealed container) and do it on a dry day (saves getting moisture in it).
It'll be easier if you jack the car up at each corner as you bleed that corner (though for the rear calipers it's quicker if the wheels are on the gound (the brake bias valve closes off the rear circuit slightly if the suspension is unloaded).
Just stick in some new fluid into the reservoir (use Halfords DOT5.1 or DOT4... any new fluid will be better than what you have in there at the moment!), undo the bleed nipple (attach a tube to it before you undo it much further) and then pump the brake pedal to get the new fluid through it. If you pump it quickly enough, you'll get new fluid through without having to tighten the bleed screw in between releasing the pedal, if you don't have a one-man kit.
You'll see the new fluid (it's almost clear, instead of black). Don't be shy to keep going till only very clean stuff comes out.
Keep going until new fluid comes out.. but stop every so often to make sure the fluid level in the reservoir hasn't dropped to empty (i.e. keep the reservoir from running out).
Do the right rear caliper first, then the left rear, right front and end at the left front.
Also do the clutch (bleed screw is on the slave cylinder under the battery.. that fluid suffers worse than the brakes and gets changed less often).
Buy 500ml of brake fluid and that ought to be enough for the whole crew.
