Best way I've heard is to first bring the car up to about 30-35 mph, then brake to a stop.  Not too gently, and not to firmly.  Do this about 10 times...I've also heard of people driving on the highway at around 75mph or so and holding the gas pedal and then basically riding the brakes off and on to take the coating off of rotors and pads.  I don't know how good that is on them though...

do not i repeat do not come to a complete stop..
this is how it is usually done
aka bedding..
find a safe road...
after u install brakes...
go out do 50 then brake till 10
first soft
and repeat increasing pedal pressure..
after bout 5-7 times.... just go home...
make sure when you park you do not use parking brake
just leave it in gear

Well this is about the same as the other ones, but I snagged this from a FAQ somewhere.

here 'tis:
</span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Quote </td></tr><tr><td id="QUOTE">go out to an open road.
accelerate to about 40 mph, then apply gradually increasing pressure to bring the car down to about 5 mph.
then, slowly accelerate back to ~40, hold it there for a bit to let the brakes cool for a moment, and slow down again.
do this 5-10 times depending on the pad.
you should feel them start to bite better and better as you go. also, you may start to smell some of the resin burning off. that's ok.
then drive a around a bit more to let them cool.
then i always like to test them with a nice hard "stop" from ~60-5, just to see if what i did was enough. then let them cool down some more before you park it.
you should be good to go after all that.

I'm sure this is too late... but it depends a lot on the pad.

Softer pads require lower speed slows and stops. Mine (a more agressive combo) is:
(40-60 slow to 30-20) x 3-5 times; then
(60-100 slow to 0) x 3-5 times.
Try not to touch the brakes after that and park for at least 30 minutes. You know you have done your job when the brakes feel like they've faded a bit (green fade) and then come back.

Other tips:
- don't smoke them (i.e., dark smoke rising from brakes)
- use firm, but not "panicky" pedal pressure
- don't do that drag the brakes while accelarating thing <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/cry.gif" border="0" valign="absmiddle" alt='

Man, the hardest part is going to be finding a long road I can do this on, with no traffic. All the roads like that I know of require me to drive 10 minutes, and this, do some braking to get to them. I wonderif my nighbors will appreciate about 6 40mph flybys.
I swear, I am just breaking the brakes in

you can still drive on the new pads just fine while you're on the way to a place to break them in.  you just don't want to do and hard, panic-type stops on pads that still have all the resins in them and aren't bedded to the rotors.  so just take it easy, go slow, and drive to where you need to go to find a straight road.  no biggie.

I do mine on a pretty urban road near my buddy's house (I have no garage).  Three lanes each way w/ a nice median.

Wait for cars to pass (i.e., light cycle).  Pull out.  Accel to 60.  Brake to necessary speed.  Pull into a turnaround.  Wair for car to pass (i.e., light cycle).  Pull out...

A little more trouble than a nice straight road, but I bet you can find one like this near you.
