As was said the peddles usually move the nose gear around 7-10 degrees. The airbus A-320 uses a different method. The nose gear is steered by electrical inpust to a servo valve which ports the required hydraulics to the appropriate actuator. This is a simple description. I could get more tech\nical but I dont want to type in that much. 3 pages in the book.
