## Discrepancy

(CAN) AFTER CREW SELECTED GEAR DOWN, THEY HAD A LOW BRAKE PRESSURE WARNING, DECLARED EMERGENCY AND LANDED USING EMERGENCY PNEUMATIC BRAKE SYSTEM TO STOP. AFTER EVALUATION, SERVICE CENTER DETERMINED THAT THE ELECTRIC MOTOR PORTION OF PUMP WAS FUNTIONAL BUT THE HYDRAULIC PUMP ITSELF HAD NO OUTPUT, PUMP WAS REPLACED.
