Proper New Rotor/Pad bedding procedure
Seems like the procedure varies for type of pad whether racing, street or different manufacturers. What is the ideal procedure for the 991 GT3 iron brakes ? I want to get a nice even pad film on the rotors. Is it outlined in the manual ? I would appreciate advice so as to do this correctly right out of the showroom. A race track won't be an option for this procedure.

You are correct, most manufactures have their own procedure depending on brake pad type. I found the attached link to the StopTech article a good primer on the subject.

The pads/rotors are not bedding in at the factory.
The pads/rotors do not need bedding in for general road use any more than for any other luxury vehicle you may buy.
The only way to properly bed a pad is to get enough heat into the annulus of the disc and this is realistically only viable/sensible at the race track or on a very clear autobahn!
Like most I had driven my car for many 1000s miles on the road before it was driven on the track. The first session on the track the brakes stunk as the gasses that bond the pad material were released from the hard braking the car had endured. The smell became no stronger that day and actually dissapeared and subsequent track days did not return. The pads and discs have been wearing excellently since. The pads/discs were finally bedded in after 5000km on two contents and 5 countries!

Ken. No problem. I learnt most of this from a real brake guru the NZ importer/distributor for Endless pads. We had my track 993 with new big brake upgrade and Endless MX72 pads at the track for a shake down the same day as I took the 991 GT3 out for its very first ever session and had just been through the whole process with the 993. There is are three straights you are doing between 100-150 mile per hour around this short track then you have to brake real hard into a sweeper or a hair pin. Only tool 2 laps of doing that and teh 993 brakes were stinking and the discs going blue on the high heat areas. This is where I learnt from him all about the process of bedding in - he explained the process of what was happening and it was perfectly what should have happened. At that time 991 GT3 had 5000km on it of fast road driving but yet as such the pads had never really been broken in to the extent required on the track and the first hard session in that car sorted that problem out very quickly!
