Hi, if you have a repair shop close by, I'd pick up a new brush. They aren't that much and easy to replace. If you still have your manual, there should be specs listed somewhere, it should give you the proper values. As for the speed control, I can't answer, never tested one, actually, never had a reason too.

You may also want to contact CharlesM here on the forums, he works for Freud, he may be able to give you some better answer(s).
