Narrative:
After landing in philadelphia; we taxied to our assigned gate. As we approached the parking line for the gate; the number 1 engine was shutdown. After engine shutdown the captain realized that the plane was not stopping with normal brake application. We both checked the AC generator switches and the standby hydraulic pump switches and observed that they were both in the on position. The captain applied the emergency parking brake as we slowly approached the gate. The nose wheel came to a stop approximately 5-6 ft from the parking T without further incident. After deplaning; the captain contacted maintenance as the #1 and #2 standyby hydraulic pump circuit breakers were in the out position.
