## Discrepancy

THE CREW REPORTED THAT WHILE THEY WERE ON A VISUAL APPROACH THE ANTI-SKID AND POWER BRAKE PRESSURE LOW LIGHTS ILLUMINATED.  THE ANTI-SKID CIRCUIT BREAKER WAS RECYCLED AND THE CREW WERE PREPARING TO USE THE EMERGENCY BRAKING SYSTEM, BUT LATER FOUND THAT THE BRAKES WERE WORKING.  WHILE TAXIING, BOTH THE PILOT AND CO-PILOTS BRAKE PEDALS WENT TO THE FLOOR.  EMERGENCY BRAKES WERE USED TO STOP THE AIRCRAFT.  MAINTENANCE REPLACED THE BRAKE PUMP ASSEMBLY AND MOTOR.  OPERATIONAL AND LEAK CHECKS WERE GOOD.  THE AIRCRAFT WAS RETURNED TO SERVICE.
