I do a lot of brake pad and rotor testing and go thru a lot of break in procedures. Heres what I've found to work the best. After you replace the pads and or rotors, pump the pedal up until its firm (yes I to have forgotten this once or twice and damn near took out a fence or something) and then go on a test drive. Drive it somewhere where you can go for a while without sitting in traffic or stopping all the time. I usually go through a series of hard brake applications from about 45 mph or so down to about 5 mph, until I smell the brakes and see smoke coming off the brakes, or until they start to fade, which ever happens first, DO NOT COME TO A COMPLETE STOP DURING THIS PROCEDURE! If you do, the extremely hot pad will transfer friction material onto the rotor at the one point where it is grabbing it while you are stopped, resulting in a slightly thicker spot on the rotor and ultimately a vibration in the pedal. After you "burn in" the pads, drive the car for a few miles without using the brakes to much to let everything cool down. You are now done breaking in the pads and rotors. You do not need to be easy on them, the harder you are on your brakes, the faster they will seat in. sorry for the long post.
