Narrative:
At cruise altitude, FL350, the left engine oil quantity fell to 1 1/2 quarts. All other engine instruments were normal. Contacted dispatch/maintenance control after performing the low oil quantity procedure. Maintenance control felt the gauge may be the only problem. Instructed to continue to dtw with atl as emergency alternate airport. 9 mins later, left oil psi began to drop. At that time we declared an emergency with ZTL and began a descent for atl. The crew performed all normal checklists including precautionary engine shutdown checklist as the oil pressure went into the red. The captain continued to fly as we were vectored for runway 9L in atl. The landing was uneventful and the aircraft was taxied off the runway and stopped. Atl crash fire rescue equipment was asked to inspect the engine for further problems. They found no other problems. We were then cleared to taxi to our gate. However, upon engine throttle up, the left brake 'locked up' and would not release. A tug was called and the aircraft was towed to the gate.

Title: DC9 FLC SHUT DOWN THE L ENG DURING CRUISE AFTER THE OIL QUANTITY AND PRESSURE DROPPED INTO THE RED. THEY DECLARED AN EMER AND DIVERTED TO LAND.
Narrative: AT CRUISE ALT, FL350, THE L ENG OIL QUANTITY FELL TO 1 1/2 QUARTS. ALL OTHER ENG INSTS WERE NORMAL. CONTACTED DISPATCH/MAINT CTL AFTER PERFORMING THE LOW OIL QUANTITY PROC. MAINT CTL FELT THE GAUGE MAY BE THE ONLY PROB. INSTRUCTED TO CONTINUE TO DTW WITH ATL AS EMER ALTERNATE ARPT. 9 MINS LATER, L OIL PSI BEGAN TO DROP. AT THAT TIME WE DECLARED AN EMER WITH ZTL AND BEGAN A DSCNT FOR ATL. THE CREW PERFORMED ALL NORMAL CHKLISTS INCLUDING PRECAUTIONARY ENG SHUTDOWN CHKLIST AS THE OIL PRESSURE WENT INTO THE RED. THE CAPT CONTINUED TO FLY AS WE WERE VECTORED FOR RWY 9L IN ATL. THE LNDG WAS UNEVENTFUL AND THE ACFT WAS TAXIED OFF THE RWY AND STOPPED. ATL CFR WAS ASKED TO INSPECT THE ENG FOR FURTHER PROBS. THEY FOUND NO OTHER PROBS. WE WERE THEN CLRED TO TAXI TO OUR GATE. HOWEVER, UPON ENG THROTTLE UP, THE L BRAKE 'LOCKED UP' AND WOULD NOT RELEASE. A TUG WAS CALLED AND THE ACFT WAS TOWED TO THE GATE.
