Default brakes: the procedure for bedding in the brake pads.

I recently bought a 99 coupe and did a brake job as follows:
turned front rotors and removed glaze from rears ( thickness specs came up mid range ) and instslled new pads.
I saw something on the forum about bedding in the brakes. I assume this for getting even piston pressure and seating the new pads.
How is this done?
Thanks alot guys for any info. KMT

do 9-10 medium hard stops from around 40 mph and then let them cool for a couple of hours

Important not to completely stop, just slow down to 5 mph. Complete stops may transfer pad material in spots.

Can also do highway driving (no stops) for like 30 minutes afterwards for cooling.

Why you bed pads. From the StopTech website: Bedding Pad to Rotor

PROPER BREAK-IN OF ROTORS AND PADS IS CRITICAL. Not properly doing so can cause permanent damage to rotors and adversely effect overall brake performance. Pads and rotors interact with each other to provide efficient brake performance. The break-in or bed-in procedure is done to condition the pad/rotor interface. Depending on the pad used, more or less pad material is uniformly transferred onto the disc as a thin film. The resins and bonding agents in some pads need to be heat cycled to work properly as well. By not properly bedding in pads, uneven pad material deposits can occur that may cause a vibration. Improper wear characteristics may also show up on either the pads, or rotors, or both. Always follow the recommended break-in procedure for any pads, rotors or brake systems. This link is to the Technical page of our website. The article titled The "Warped" Brake Disc and other Myths of the Braking System has more details about the effect of the pad and rotor together
