I was told by an automotive engineer whom I contact regularly with, to accelerate to 35MPH (immediately after brake job), and hit the brakes firmly (but not enough to activate the ABS). Repeat the process for 12 times. Then, drive for several miles to cool off, then repeat the process again.
The idea behind this is to heat the rotors enough to burn off any contaminants from the brake job and to burnish the rotors for the best finish, and deposit a lite layer of pad material on the rotors.

I warped my Brembo BBK on one of my previous cars in less than 12k miles going out and doing the beding in right away. Got new rotors and heatcycled them for a few hundred and to the day i got rid of the car the rotors wernt warped

O'rly?
Heat Cycling ???
FWIW, I just got a new brake job last Saturday. New AutoZone Duralast Ceramic pads (in the front) and the AutoZone Duralast Semi-Metallics (in the back); don't ask me why I have ceramics in the front and semi-metallics in the back...they only make them that way...
Nevertheless, the car had 89,000 miles on it and was on the original brakes and rotors. 99% city driving of 1-3 mile trips...so imagine how much the brakes were used. Pads still had some left and could've gone another 5K. (Will post pics)
The indy mechanic went ahead and installed new pads, and turned the rotors. ($200 total) When I left...I just took it up to 35MPH...and applied the brakes gently several times on the way home. The following day, I took it through SF Chinatown, as well as Mission St., so I got PLENTY of stops from 30-40MPH...all gently. I didn't get the engineer's e-mail until Monday so it was a bit too late.

Hard bedding ruined my Rotora slotted. Day I changed them I took it up on the mountain and did a hard brake coming down, drove for a bit to cool, then repeated 3 times.
Now I get massive vibration 15k later. Damnit
