Narrative:

After flying to sju we landed at maximum grott weight on runway 10 with a wet runway. Rollout and braking were normal with taxi of about 3 mi to reach our assigned parking gate. Our ramp signalman who is a contract employee of sju port authority signaled us to a stop, then to cut engines. Then that the chocks were in place. The seat belt sign was turned off. Upon inquiring about the temperature of the brakes from the flight engine we were informed that the brakes were in low yellow due to maximum landing weight short runway and extended taxi to the gate. With the engines shut down, I released the brakes to help dissipate the heat buildup. I watched the side of the jetway for approximately 15 seconds to assure myself that the aircraft would not move and then commenced the secure cockpit checklist. About 30 seconds later the copilot stated we were moving and I immediately applied full brakes. We had rolled about 5' backwards due to about a 3 degree slope at that gate. Several passenger and 1 F/a were off balance and fell into others or seats or galley walls. No injuries or damage except for 1 F/a sprained her wrist. Reports were made to station manager, port authority and company chief pilot. The ground personnel had only put 1 chock in place in front of the nose gear, so the aircraft was not sufficiently chocked to release the hot brakes.

Narrative: AFTER FLYING TO SJU WE LANDED AT MAX GROTT WT ON RWY 10 WITH A WET RWY. ROLLOUT AND BRAKING WERE NORMAL WITH TAXI OF ABOUT 3 MI TO REACH OUR ASSIGNED PARKING GATE. OUR RAMP SIGNALMAN WHO IS A CONTRACT EMPLOYEE OF SJU PORT AUTHORITY SIGNALED US TO A STOP, THEN TO CUT ENGS. THEN THAT THE CHOCKS WERE IN PLACE. THE SEAT BELT SIGN WAS TURNED OFF. UPON INQUIRING ABOUT THE TEMP OF THE BRAKES FROM THE FLT ENG WE WERE INFORMED THAT THE BRAKES WERE IN LOW YELLOW DUE TO MAX LNDG WT SHORT RWY AND EXTENDED TAXI TO THE GATE. WITH THE ENGS SHUT DOWN, I RELEASED THE BRAKES TO HELP DISSIPATE THE HEAT BUILDUP. I WATCHED THE SIDE OF THE JETWAY FOR APPROX 15 SECS TO ASSURE MYSELF THAT THE ACFT WOULD NOT MOVE AND THEN COMMENCED THE SECURE COCKPIT CHKLIST. ABOUT 30 SECS LATER THE COPLT STATED WE WERE MOVING AND I IMMEDIATELY APPLIED FULL BRAKES. WE HAD ROLLED ABOUT 5' BACKWARDS DUE TO ABOUT A 3 DEG SLOPE AT THAT GATE. SEVERAL PAX AND 1 F/A WERE OFF BALANCE AND FELL INTO OTHERS OR SEATS OR GALLEY WALLS. NO INJURIES OR DAMAGE EXCEPT FOR 1 F/A SPRAINED HER WRIST. RPTS WERE MADE TO STATION MGR, PORT AUTHORITY AND COMPANY CHIEF PLT. THE GND PERSONNEL HAD ONLY PUT 1 CHOCK IN PLACE IN FRONT OF THE NOSE GEAR, SO THE ACFT WAS NOT SUFFICIENTLY CHOCKED TO RELEASE THE HOT BRAKES.
