## Discrepancy

LOW BRAKE PRESS & ANTI-SKID INOPERATIVE ANNUNCIATOR LIGHTS ILLUMINATED & REMAINED ON AFTER SELECTING GEAR DOWN. CREW APPLIED ABNORMAL CHECKLIST AND DIVERTED TO KMIA FOR RUNWAY LENGTH. EMERGENCY WAS DECLARED. LANDING WAS UNEVENTFUL. MAINTENANCE REPLACED THE BRAKE CONTROL MOTOR RELAY, ANTI-SKID PRESSURE SWITCH, BRAKE HYDRAULIC PUMP, AND BRAKE PUMP MOTOR. GEAR SWINGS AND OPS CHECKS WERE GOOD. AIRCRAFT WAS RETURNED TO SERVICE.
