MD80 CREW HAD A HIGH SPD ABORTED TKOF AT DFW.

Narrative

EVERYTHING SEEMED NORMAL BOARDING; ETC. PAX BOARDED; AGENT CLOSED THE DOOR; WE DID THE SAFETY DEMO; COMPLIANCE CHKS; AND SAT DOWN IN OUR JUMP SEAT. CAPT SAID FLT ATTENDANT 'PREPARE FOR TKOF.' WE STARTED DOWN THE RWY; THEN SUDDENLY THE BRAKES SLAMMED ON AND AT THAT POINT I KNEW WE WERE ABORTING TKOF. I LET THE #3 FLT ATTENDANT KNOW SINCE SHE WAS NEW. LOTS OF THOUGHTS WERE IN MY HEAD; MAIN ONE BEING I THOUGHT WE WERE GOING TO HIT ANOTHER ACFT. AFTER COMING TO A COMPLETE STOP I WAITED 30 SECONDS AS INSTRUCTED BY THE CAPT (IN BRIEFING); BEFORE MAKING CONTACT WITH THE PLTS. CAPT THEN CAME ON THE PA AND MADE AN ANNOUNCEMENT SAYING THAT EVERYTHING WAS OK; THERE WAS A FUEL FLOW INDICATOR PROB FOR THE L ENG. WE THEN TAXIED BACK TO THE GATE WHILE MECHS MET OUR FLT. THE #2 BRAKE HAD OVERHEATED DUE TO THE EVENT AND WE WAITED FOR THAT TO COOL DOWN. AFTER ABOUT 40 MINS; WE TOOK THE SAME ACFT AND DEPARTED FOR DTW AS ORIGINALLY PLANNED. WE WAITED 1 HR TO TAKE OFF THE SECOND TIME DUE TO TSTMS IN THE AREA.
