Narrative:

Power brake circuit breaker popped when landing gear was extended; illuminating the lo brake press and antiskid inoperative warning lights. We executed a missed approach and received delay vectors to complete the appropriate checklists. During vectors; we informed ATC of the problem and notified them that we would need to stop on the runway and be towed. ATC acknowledged; and we returned for the approach. Approach and landing occurred without incident and we stopped on the runway using the emergency braking system. Airport operations escorted the tug on the runway and we were towed to the FBO without incident.
