Narrative:
ECAM notified crew of low yellow system hydraulic fluid. System was shut down per procedures. Consulted with dispatch and maintenance in regards to condition. Notified station and FSS of our situation. Dispatch coordinated with ATC for runway 32L. Landed into the wind; used runway 32L due to limited potential braking and loss of thrust reverser on right engine. Upon uneventful landing; heavy vibration was felt in nose gear and air frame. Fearful of additional safety issues; cleared runway and had fire crews look over aircraft for additional problems and fire risks associated with hydraulic leak. Shut down aircraft on taxiway until communication with ground crews confirmed safe operation of aircraft was assured. Taxied to the international gates without additional problems with fire watch trailing the aircraft. Landed with minimum brakes but still had hot brakes on right side of aircraft (330 degrees). Hydraulic fluid and smoke was reported initially by ground fire crew coming from right main brakes. Maintenance cleared us to taxi to the gate once they looked over the aircraft on taxiway a. ATC provided excellent service with no delays. Landed as soon as possible given the location and time remaining from the initial site of the event.

Title: AN A320 LOST YELLOW HYD SYS FLUID RESULTING IN A PROCEDURAL SECURING OF THE AFFECTED SYS. EMER DECLARED; HOT BRAKES ON LNDG.
Narrative: ECAM NOTIFIED CREW OF LOW YELLOW SYS HYD FLUID. SYS WAS SHUT DOWN PER PROCS. CONSULTED WITH DISPATCH AND MAINT IN REGARDS TO CONDITION. NOTIFIED STATION AND FSS OF OUR SIT. DISPATCH COORDINATED WITH ATC FOR RWY 32L. LANDED INTO THE WIND; USED RWY 32L DUE TO LIMITED POTENTIAL BRAKING AND LOSS OF THRUST REVERSER ON R ENG. UPON UNEVENTFUL LNDG; HVY VIBRATION WAS FELT IN NOSE GEAR AND AIR FRAME. FEARFUL OF ADDITIONAL SAFETY ISSUES; CLRED RWY AND HAD FIRE CREWS LOOK OVER ACFT FOR ADDITIONAL PROBS AND FIRE RISKS ASSOCIATED WITH HYD LEAK. SHUT DOWN ACFT ON TXWY UNTIL COM WITH GND CREWS CONFIRMED SAFE OP OF ACFT WAS ASSURED. TAXIED TO THE INTL GATES WITHOUT ADDITIONAL PROBS WITH FIRE WATCH TRAILING THE ACFT. LANDED WITH MINIMUM BRAKES BUT STILL HAD HOT BRAKES ON R SIDE OF ACFT (330 DEGS). HYD FLUID AND SMOKE WAS RPTED INITIALLY BY GND FIRE CREW COMING FROM R MAIN BRAKES. MAINT CLRED US TO TAXI TO THE GATE ONCE THEY LOOKED OVER THE ACFT ON TXWY A. ATC PROVIDED EXCELLENT SVC WITH NO DELAYS. LANDED ASAP GIVEN THE LOCATION AND TIME REMAINING FROM THE INITIAL SITE OF THE EVENT.
