## Discrepancy

DECENDING THROUGH FL200, THE LOW BRAKE PRESSURE AND ANTISKID INOP ANNUNCIATION BEGAN TO FLICKER THEN AFTER 3 MIN BECAME SOLID.  THE GEAR WAS THEN EXTENDED AND THE LIGHTS EXTINGUISHED.  UPON GEAR RETRACTION, THE RT MAIN GREEN GEAR DOWN LIGHT FAILED TO EXTINGUISH. CREW THEN COMPLEATED THE EMERGENCY BLOW DOWN PROCEDURE AS A PRECAUTION.  LANDING WAS NORMAL AND BRAKES WORKED NORMALLY.  R & R RT DOWNLOCK ACTUATOR SWITCH WITH NEW IAW MM 32-30-04.  OPS CHECKED NORMAL.
