Yes there are adapters available for Shimano...
disc brakes. What adapter you need depends on several variables. Universal Cycles (www.universalcycles.com) carries them. Below is a link to their page for the product I think you are looking for. With the variables that are possible with your set up I would highly recommend that you call them to make sure of what you need. Have your measurements ready, i.e. Rotor size, tab style and measurement on the fork (74mm post mount ala manitou, or 51mm tab mounts, most others), and the model of brake. They should be able to hook you up. Their number is (800) 936-5156. The link below is just to show you what you are looking at. Don't feel like a fool, it's not an uncommon oversight when switching from a fork with a manitou style post mount to a fork with IS mounts. Anyway, congrats on your new fork. Hopefully Universal can solve your problem for you.
Universal cycles is probably not the only online source for the adapters. But they are the only ones that I personally know of that carry them on a regular basis. Hope this helps you out.
