Narrative:

With captain as PF and departing runway xxr master caution illuminated at approximately 95 knots. Captain made decision to reject and as thrust levers were retarded first officer made the 100 knot call followed by 'doors light'. Rejected takeoff was completed without incident and ca taxied clear of runway. The rejected takeoff QRH checklist was accomplished and the brake cooling chart was used to determine necessary brake cooling time. Captain spoke with flight attendant re: rejected takeoff and made subsequent PA to passengers. Once the required cooling time was complete the takeoff was accomplished and the flight continued without further issue.

Original NASA ASRS Text

Title: The Captain reported observing a master caution warning light illuminate during the takeoff roll and he initiated a high speed abort. After the appropriate checklists were completed; the anomaly corrected; and the brake cooling issue addressed; a subsequent successful takeoff was completed.
