Aircraft
We performed a standard approach and landing; including all call outs and aircraft indications. As we were approaching taxiway Delta decelerating through 60-50 knots; I released the pressure on the brakes. The aircraft instantaneously swerved to the right about 30 [Degrees]. Directional control was challenging. My FO (First Officer) asked if I was OK; and realized that I wasn't incapacitated but struggling to regain control of the aircraft.My immediate thought was that we had a malfunction with the tiller; and I started to use the rudders for directional control; and I believe I pulled the flight spoilers handle. I was fearful of leaving the runway we were about 20 ft. off centerline and pointed towards the grass. I applied the brakes again and regained enough control to get the aircraft headed away from the runway's edge. But now we were headed left of the centerline 30-40 [Degrees]. I managed to get the aircraft headed back towards the right; and we came to a stop pointed right towards taxiway Delta. Tower queried us if we needed assistance and alerted us to a plane on short final. I responded; not just yet. The FO and I scanned the cockpit for cautions messages or warnings or any abnormal indications. We saw nothing. I slowly added power to roll the A/C (Aircraft) off the active runway. Once clear of the active runway; we set the parking brake; performed the after landing check; and continued checking abnormalities or indications. The FO checked the CB (Circuit Breaker) panels. Everything was normal. I slowly added power and tested the tiller and brakes for functionality. All indications and responses were normal; and we decided to taxi to the gate. The Aircraft taxied and performed normally. The right side brake indication was 5 all others were 2 & 3. I first thought it was an asymmetrical thrust reverser. I now believe after contemplation and reflection that it was a stuck inboard brake.
