Narrative: We had a deferred APU bleed air and did a air start at the gate then went to spot 3 and did a cross bleed start. We taxied out to Runway 4L and it was my leg as Pilot Flying. ATC was issuing windshear loss of 15 kts. on final for Runway 4R and we planned for a Vr max for takeoff for the windshear. Wind was 330 gusting to 27 kts. We were cleared for takeoff I set 1.1 EPR called for set thrust. Captain set it. Check thrust. Thrust checked we were accelerating. We had not hit 100 kts. when ATC issued the reject. We rejected the takeoff. I called for the flight attendants to remain seated and we taxied off the runway to Taxiway P about 3;000 ft. down the runway. I ran the QRC and pulled the QRH. Another aircraft said they saw smoke coming from our gear so we asked [Crash Fire rescue] to come. Brakes hit 3 on the left side with the white box. We checked on the passengers and flight attendants. I called Maintenance and they said we would have to go to the ballpark for inspection. [Software] chart showed 56 min I rounded up to 100 kts. as I know we were below that. [Crash Fire Rescue] could not inspect our gear because they needed us to shutdown engines which we could not do because of the inoperative APU. We taxied to the [ramp] and Maintenance met us and we wrote up the reject there. We also notified Dispatch and the passengers and flight attendants. The brakes went back to 0 and after shutting down the left engine; Maintenance cleared us. We did a crossbleed at Taxiway Y short of Taxiway U and got a new release with the fuel we had; new to data and departed.


Second narrative: Gusty winds on clear day. LLWS (Low Level Wind Shear) advisories in effect in departure ATIS. First Officer's takeoff. Cleared for takeoff and approaching 80 kts.; tower cancelled our takeoff clearance due to aircraft on Runway 4R executing a go-around due to wind shear. We completed the Rejected Takeoff Checklist and were cleared off the runway onto Taxiway P; between the runways; to run checklists and resequence for takeoff. Tower noted seeing smoke around the brake assemblies; so we had [Crash Fire Rescue] inspect the aircraft. Referencing the brake cooling checklist; we needed 56 mins for cooling. Brake temperatures reached 3 for 230.0. Because of limitations due to a deferred APU; we were not able to shut down both engines for complete inspection by [Crash Fire Rescue]. With 40 minutes remaining for cooling; we decided to have Maintenance and [Crash Fire Rescue] check the aircraft. Brake temperatures was 0 by time we reached the [parking spot]. Shutdown 1 engine shutdown for inspection and Maintenance and Crash Fire Rescue saw no damage and cleared us to go. Conferred with [Maintenance] and Dispatch and updated our weights and flight plan. Started 2nd engine; taxied out; and departed off Runway 4L.


Synopsis: B757 flight crew reported a rejected takeoff that resulted in hot brakes and a flight delay.
