In response to anti-skid and brake failure warnings on final approach the flight crew of a ce-560XLS...

Narrative:

All was normal until final approach in visual conditions. On final; 'antiskid inoperative' annunciator appeared; at same time 'power brks' breaker was popped. Advised tower that we wished to go around and troubleshoot. Completed the go-around and was handed off to approach. They provided delay vectors while we ran the QRH. A problem arose; as the QRH for the 'antiskid inoperative' does not include the 'power brks' breaker. Instead; it looks at the 'skid cont' breaker. The rest of the QRH was completed. With this discrepancy; and no time issues; we attempted to contact company maintenance both by flight phone and personal device; with no success. As we returned to the problem; the 'lo brake press' light was now also illuminated. This QRH was also followed. It was now determined that we would be using the emergency brake handle on landing to stop. The emergency was declared with tower; and asked trucks to be standing by. We decided to use runway 28 now; as weather was not a factor and this provided long surface. Passengers were briefed; and the approach and landing were uneventful. We were chocked on runway until a tug was able to take us to the FBO.I do not have suggestions as to how to avoid a recurrence of this event; but it may be necessary to follow up with the appropriate people as to the QRH. The initial light and circuit breaker were not as we expected in the QRH usage.

Title: In response to anti-skid and brake failure warnings on final approach the flight crew of a CE-560XLS executed a go-around; followed the appropriate QRH procedures; declared an emergency and landed safely using max reverse thrust and emergency brakes to a full stop.

Narrative: All was normal until final approach in visual conditions. On final; 'ANTISKID INOP' annunciator appeared; at same time 'PWR BRKS' breaker was popped. Advised Tower that we wished to go around and troubleshoot. Completed the go-around and was handed off to Approach. They provided delay vectors while we ran the QRH. A problem arose; as the QRH for the 'ANTISKID INOP' does not include the 'PWR BRKS' breaker. Instead; it looks at the 'SKID CONT' breaker. The rest of the QRH was completed. With this discrepancy; and no time issues; we attempted to contact Company Maintenance both by flight phone and personal device; with no success. As we returned to the problem; the 'LO BRAKE PRESS' light was now also illuminated. This QRH was also followed. It was now determined that we would be using the emergency brake handle on landing to stop. The emergency was declared with Tower; and asked trucks to be standing by. We decided to use Runway 28 now; as weather was not a factor and this provided long surface. Passengers were briefed; and the approach and landing were uneventful. We were chocked on runway until a tug was able to take us to the FBO.I do not have suggestions as to how to avoid a recurrence of this event; but it may be necessary to follow up with the appropriate people as to the QRH. The initial light and CB were not as we expected in the QRH usage.
