When you've finished bleeding the system, step on the pedal a few times, going only around 1/2 way to the floor with the pedal on each stroke (you're only going 1/2 way down so that you won't run the risk of tripping the warning light switch). ....

Repeat this work-the-pedal / check the fluid level process until you get a firm pedal under your foot. If you neglect do do this process, the pedal will go straight to the floor when you step on it, cuz the pistons will still be recessed in the caliper bores. This can lead to Very Bad Things happening if you test drive the car before you've obtained a firm pedal -- it's the sort of nasty surprise nobody needs.

Remove the pads as outlined by Bruthish, and press the pistons fully into the calipers with the C-clamp (don't go crazy with the pressure, just push 'em all the way back in).

2. Put a length of hose on the bleeder screw at each wheel... I use clear plastic hose (polyethylene, if I recall correctly) that can be purchased at Home Depot / Lowe's in various diameters....you can watch what's coming out of the calipers as it's bleeding.
