## Discrepancy

CREW REPORTED THAT AFTER LANDING THE BRAKES WERE SLUGGISH AND THAT THE PEDALS HAD TO BE PUSHED ALL THE WAY TO THE FLOOR BEFORE THEY WERE EFFECTIVE.  MAINTENANCE BLED ALL 4 BRAKE SYSTEMS.  AIR WAS FOUND TO BE PRESENT IN THE INBOARD AND OUTBOARD BRAKE SYSTEMS.  THE AIRCRAFT THEN RETURNED TO SERVICE AND THERE HAVE BEEN NO FURTHER OCCURRENCES NOTED.
