Synopsis
Air carrier flight crew reported a loss of directional control during landing rollout which required maximum brake effort by both pilots to avoid a runway excursion.
Narrative
I; First Officer (FO; was the Pilot Flying (PF) the aircraft and we determined to land on Runway XXR (RNAV Approach) at ZZZ1; it was a normal approach and landing right on the center line. The aircraft nose and main landing gears were on the ground rolling to get out on the Taxiway. During our briefing; we agreed not to step hard on the brakes because we were going to exit close to the end of the runway. The aircraft started to slow down (around 80 knots- in center line still) then around 80 to 70 knots the aircraft started to pull to the left really hard; the Captain (CA) said to come back to the center I told him I was unable. The CA said (my controls) and then exchanged flight control to the Captain; the Captain was struggling to keep the aircraft directional control - trying to come back to the center of the runway; then I step back on the pedals (brakes) to help to stop the aircraft. We were able to stop the aircraft on the left side of the runway then the CA shut down the engines for safety and make a passenger announcement. The tower ask if we need any assistance and the Captain answer yes; so the fire department truck and the airport authorities arrived. The CFR crew walked around to check the aircraft and confirmed that everything looks normal; the CA was on the phone getting the information to move the aircraft; and after confirmation the ramp crew hooked the airplane to the gate with no issues.
Second reporter narrative
I was acting as Pilot Monitoring (PM) and the First Officer (FO) was Pilot Flying (PF). We planned the visual approach to Runway XXR. The arrival and approach were completed with no issues. The FO landed on centerline. After touchdown; at approximately 70 to 80 knots; I noticed the aircraft had begun to drift to the left of centerline. At that time; I took control of the aircraft. I felt a very aggressive pull to the left; I applied maximum manual braking and came to a full stop on the runway. I notified tower that we required assistance; and made a PA to the cabin to please remain seated. We immediately shut down the engines and confirmed with the flight attendants that everyone on the airplane was safe. The Crash Fire Rescue (CFR) crews advised us that everything looked normal on the aircraft and all of our thermal temperatures appeared normal as well. After speaking with contract maintenance and Maintenance Control it was determined the aircraft was safe to tow to a gate. At that point; our ramp crew towed us to the gate with no further issues.
