I WAS PULLING INTO A PARKING SPOT IN THE UPPER PARKING LOT AT WORK. I STEPPED ON THE BRAKE PEDAL SO THAT I COULD STOP AND PARK BUT THE PEDAL WAS HARD AND HAD NO GIVE. THE CAR CONTINUED TO ROLL FORWARD OVER A CURB AND PARTLY DOWN A SMALL SET OF STAIRS THAT GO FROM THE UPPER PARKING LOT TO THE LOWER PARKING LOT. THE CAR STOPPED WHEN IT HIT A METAL RAILING AND I SHIFTED THE CAR INTO PARK.
