I have a simple bed-in procedure I've used the last few years. Most recently, a few weeks ago w/Akebono ceramics on a Lexus. Great results.
This was recommended by a manufacturer when I did a meta-survey of this subject. It sounded the most physically logical to me of my survey and conformed closely with what had worked perfectly for decades for me with motorcycles.
A) At 60mph, brake agressively down to 30mph, near lock-up.
B) release at 30 mph and cruise for a mile or so for cooling, while accelerating back to 60.
c) Repeat a/b for 10 cycles.
I did this recently and the results were great; the new ceramic pads bite amazingly,no dust, and don't fade from what I have tried yet (there was new fluid a few months before the pad swap).
I am sure you can get away with no break-in, but this really seems to split the difference between excessive wear-in and nothing, and it gives results consistently. It is easy to do unless you live in a dense urban area.
I'm a bit of a fetishist about brakes; my bikes/cars have the best pads I can get, braided lines on any performance machine, bleeds once a year and flushes every 2. I have seen a difference in long-term performance and longevity with this proceedure.
