## Discrepancy

BFM - FLT 9244 EN ROUTE BFM TO PHL.  AFTER TAKEOFF, A STRONG ODOR ENTERED THE COCKPIT RESULTING IN THE BURNING SENSATION OF THE CREW'S EYES.  THE CREW DONNED THEIR OXYGEN MASKS AND RETURNED TO FIELD BFM WITHOUT FURTHER INCIDENT.  MAINTENANCE REPLACED A LEAKING NUMBER FOUR BRAKE ASSEMBLY, AND SERVICED A DEPLETED BLUE HYDRAULIC SYSTEM.
