I still have the OE brake pads on my front and have changed the rears twice. Each time, I merely use only moderate rear brake pressure while the pads are new. But, are your brakes the integrated servo brakes? If so, proper bedding in requires short, mpoderate applications for the first, say, 50 miles.
Finally, when servicing my Brembo brakes (ABSII), I remove the used pads and rough them on a flat surface (concrete garage floor) and re install them until their end-of-life. This helps retain excellent feel and performance of the brakes.
