Synopsis
CRJ flight crew reported left Brake Temperature thermal runaway during arrival taxi. After completing appropriate QRH procedure and a ARFF wheel inspection the high temperature was due to an indicator failure and aircraft taxied to gate safely.
Narrative
Captain (CA) was Pilot Flying (PF). We flew ZZZ1 XX with no issue and landed. Taxied off XX onto Runway YY. Ground told us to take Kilo and hold short abeam gate 33. After I read this back I began my after landing flow. I noticed the L BTMS [Brake Temperature Monitor system] Indicator on the most left wheel began to skyrocket. It went from 2 to 15 to 20 and then red. It gave us Master Warning Brake Overheat. ATC cleared us to taxi to the gate; but we told them we need to stay put and run a checklist. I ran Quick Reference Checklist (QRC) then Quick Reference Handbook (QRH). The Captain directed me to call ATC and ask for the fire trucks to take a look at the brakes; as we had no other abnormal indications (the BTMS directly next to it was reading only 02 and green). An airline taxiing by told us they did not see any smoke or fire; and the fire trucks relayed the same information when they arrived. They also took the temperature of the brakes. We elected to continue to the gate. Maintenance deferred the indicator.
Second reporter narrative
After landing and clearing active Runway XX ZZZ; we received a Brake OVHT message on the left outboard main Brake Temperature Monitoring System (BTMS) indicator while taxing on taxi way Juliet. We stopped aircraft and First Officer (FO) ran Quick Reference Checklist (QRC) and Quick Reference Handbook (QRH). We notified Ground Control to roll the fire trucks. We notified the Flight Attendants and passengers of the event and to remain seated while they investigate. The fire dept. inspected and we were given the all clear. We notified Ground we were ready to taxi to gate.
