Narrative:

While on approach to runway 36R at cvg and shortly after landing gear extension, both antiskid inboard and outboard caution messages appeared. At this time the first officer was at the controls. We performed a missed approach and upon gear retraction the messages disappeared. We re-entered the pattern for another approach, this time dropping the gear earlier and received the same 2 messages. We informed ATC that we had the same problem recur, declared an emergency and asked to be removed from the pattern to perform the appropriate QRH procedure. After the QRH procedure was complete, dispatch, the flight attendant and the passenger were notified. It was then decided that the captain would perform the landing and the controls were xferred. We re-entered the pattern and landed the airplane without further incident.
