    I am sure it's not tool steel.

    My BRAKING rotors are carbon steel that has been hardened, thats why they rust here in Monterey. I talked with my local CNC guy because I wanted a 170mm rotor made to fit my Manitou and he checked them out and he checked the material and said is was a high carbon steel which was hardened and it would run me about 150 bucks for a rotor. I do think the shimano rotors are stainless though, they never seem to rust out as quickly and when they do, they just pit/spot slightly.

    yea the ebc page shows that. its carbon/steel or stainless/steel.

    F.O.G. call up Hope. they will make you a rotor that fits.

    oh that custom rotor should set you back something like 40-70. i had some made for 45 a piece but they were for some Hope brakes anyway..
    also try Galfer rotors, they make a ton. just be careful on width of them.

    you can also get aluminum rotors and carbon rotors.
    i'll look up the thread.

    edit:
    there was a pretty in depth thread about disc brakes on here where different materials of pads and rotors were discussed intelligently but it seems to have dissapeared.

    They must get surface ground to make sure they are flat, n'est-ce pas?

    I don't know what pads the new carbon bicycle brakes take, hell i don't even know if they work, but they are there. Aluminum pads have been available from Stan (as in no-tubes) since roughly the date of the thread i mentioned, around mid may of 2002, and don't require (off the top of my head) special pads. Stan also has a new rotor out which is coated alu, but i don't know more than that except it looks cool:
