Gently the first few times, just in case it's not all bolted down properly!
In the info pack for the Ferodo pads, I think it tells you to do several runs of increasing speed, braking each time to a full stop. That's what I did anyway.
The trouble with the "drive gently for 300miles" theory is that:
a: - what happens if you need to make an emergency stop and they're not bedded in and don't perform properly?
b: - you can drive 300miles without applying the brakes hardly at all if you're doing motorway driving, so how has that helped bed in the brakes?
Brand new pads/discs definitely need a bedding in period to work properly. I don't understand the science, but I do know that you actually need to lay down a surface coating of the pad on the disc itself, and that the heating process actually helps cure the pad material.

ps - what pads/ fluid are you using? I'd say it's probably also worth your while checking the brake system with a quick bleed after a few days - just incase there are some trapped air pockets that need displacing after having pumped the fluid around and got heat in the calipers etc.

The pads will be whatever comes as standard with a Big Red kit (I think they are Brembos with Porsched logos aren't they?) I've asked Tom to use a top spec fluid but I don't know what he's goning to use, I'll PM him.
The pads in Chas's new kit are Textar (Porsche OEM). I am not sure of their recomended bedding in procedure. His new disks are nice though as they have been machined after the bells were attached to ensure the disks run true. The disks do not look pre-conditioned (cost plus option from some disk manufacturers).

Thanks Lee - I wasn't ignoring you're advice to ask a Porsche dealer - I just don't know any I can ask! Presumably I tell them they are disks and calipers for a 993?
Most importantly, don't let it come to a complete halt after heavy braking unless it is absolutely necessary from a safety point of view. The pad material will melt onto the disk.
Yes, to follow up on Markus's post: when you do stop, don't stay stationary with your foot on the brake pedal as this will cause the pad to stick to the disk. You can see this on lots of cars, especially automatics, and always on your rear discs (from the handbrake).
