Narrative:
We received takeoff clearance for runway 4R, at 217000 pounds. Runway wet, maximum power was applied at 1.77 EPR. At approximately 100 KTS, the right engine generator failed. The abort was started at approximately 100 KTS, V1 was 131 KTS -- well below. The aircraft was stopped and exited the runway. We checked the brake cooling chart, called maintenance, and taxied back to the gate. All entries were made for the idg and items. After maintenance repaired the aircraft we then left for lax. Callback conversation with reporter revealed the following information: the reporter stated the direct cause of the rejected takeoff was the #2 engine integrated drive generator failure. The reporter said maintenance found the integrated drive generator low on oil and then replaced the generator control unit. The reporter stated the trip was delayed longer after servicing the integrated drive generator oil as it was necessary to run the engine to check for leaks.

Title: A B757 REJECTED TKOF AT 100 KTS DUE TO #2 INTEGRATED DRIVE GENERATOR FAILURE CAUSED BY A LOW OIL CONDITION.
Narrative: WE RECEIVED TKOF CLRNC FOR RWY 4R, AT 217000 LBS. RWY WET, MAX PWR WAS APPLIED AT 1.77 EPR. AT APPROX 100 KTS, THE R ENG GENERATOR FAILED. THE ABORT WAS STARTED AT APPROX 100 KTS, V1 WAS 131 KTS -- WELL BELOW. THE ACFT WAS STOPPED AND EXITED THE RWY. WE CHKED THE BRAKE COOLING CHART, CALLED MAINT, AND TAXIED BACK TO THE GATE. ALL ENTRIES WERE MADE FOR THE IDG AND ITEMS. AFTER MAINT REPAIRED THE ACFT WE THEN LEFT FOR LAX. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE DIRECT CAUSE OF THE REJECTED TKOF WAS THE #2 ENG INTEGRATED DRIVE GENERATOR FAILURE. THE RPTR SAID MAINT FOUND THE INTEGRATED DRIVE GENERATOR LOW ON OIL AND THEN REPLACED THE GENERATOR CTL UNIT. THE RPTR STATED THE TRIP WAS DELAYED LONGER AFTER SVCING THE INTEGRATED DRIVE GENERATOR OIL AS IT WAS NECESSARY TO RUN THE ENG TO CHK FOR LEAKS.
