Aircraft
We were cleared for takeoff on [a runway that was] over 11000 feet long; 200 feet wide. The First Officer was performing Pilot Flying duties. I was performing pilot monitoring duties. Upon initiating the takeoff roll; the aircraft was accelerating sluggishly. Engine instruments were normal - the First Officer had transferred control of the throttles to me per normal takeoff flows. The AC was accelerating straight down the runway. As the situation progressed; and at approximately 75kts; I announced abort and pulled the throttles back to idle. We advised ATC of the situation. Once clear of the runway; we advised Ops of the situation. The aircraft was able to taxi. Subsequently; we taxied to the gate and dropped our passengers off. The aircraft was written up at this time; [Maintenance] advised; and I also discussed what happened with the mechanics.
Air carrier flight crew reported rejecting the takeoff at approximately 75 kts because the aircraft was not accelerating normally; apparently due to a brake issue.
