Narrative:
Initiated abort during takeoff roll due to brake overtemp gauge indicating a brake overheat. I observed the temperature gauge needle fluctuating full scale; followed by the overheat light illuminating. At 100-110 KTS; abort was initiated with approximately 12000 ft of runway remaining. Runway was dry. Aircraft weighed approximately 144000 pounds; V1 was 150 KTS. Runway was cleared and crash fire rescue equipment requested to inspect landing gear area. It was found that the #1 wheel had experienced a wheel bearing failure and the wheel had damaged the brake assembly. Aircraft could not be taxied/towed until wheel assembly was replaced. Given the conditions; i.e.; long dry runway; I felt aborting was the prudent option.

Title: AN MD82 FLIGHT CREW EXPERIENCED BRAKE OVER TEMP WARNING ON TAKEOFF ROLL AND REJECTED THE TAKEOFF AT APPROX 100 - 110 KTS.
Narrative: INITIATED ABORT DURING TKOF ROLL DUE TO BRAKE OVERTEMP GAUGE INDICATING A BRAKE OVERHEAT. I OBSERVED THE TEMP GAUGE NEEDLE FLUCTUATING FULL SCALE; FOLLOWED BY THE OVERHEAT LIGHT ILLUMINATING. AT 100-110 KTS; ABORT WAS INITIATED WITH APPROX 12000 FT OF RWY REMAINING. RWY WAS DRY. ACFT WEIGHED APPROX 144000 LBS; V1 WAS 150 KTS. RWY WAS CLRED AND CFR REQUESTED TO INSPECT LNDG GEAR AREA. IT WAS FOUND THAT THE #1 WHEEL HAD EXPERIENCED A WHEEL BEARING FAILURE AND THE WHEEL HAD DAMAGED THE BRAKE ASSEMBLY. ACFT COULD NOT BE TAXIED/TOWED UNTIL WHEEL ASSEMBLY WAS REPLACED. GIVEN THE CONDITIONS; I.E.; LONG DRY RWY; I FELT ABORTING WAS THE PRUDENT OPTION.
