Narrative:

We touched down on runway after an uneventful approach. As soon as I applied brakes and deployed the thrust reversers; the aircraft exhibited a strong pull to the left. I was able to maintain centerline using about 3/4 of full right rudder deflection and maximum right braking. Braking performance was noticeably degraded; but not to a degree where I feared an overrun. I exited the runway on a high-speed taxiway and the aircraft appeared to handle fine at that point; so I slowly taxied to the gate and we deplaned. On the mfd (multi function display) hydraulics page; I noticed that the rh ib (right hand inboard) brake temperature was completely cold; the rh ob (right hand outboard) brake was warmer than normal for after landing; and both lh (left hand) brake temps were normal. This indicated to me that the rh ib (right hand inboard) brake had not done anything during my landing; which explained the hard left pull I felt when braking. This was my crew's last flight before heading to an overnight; so I told the gate agent to hold boarding; I called maintenance; and I explained the situation to the inbound crew.sudden large yawing moment upon touch down. It felt similar to the engine failure before V1 drills in the sim; so in the heat of the moment I suspected some sort of thrust reverser issue rather than a failed brake. The brake temperature indication is how I later 'detected' that it was a brake issue. A few hours later I spoke with the captain who swapped into the plane; he told me that maintenance had found that the rh ib brake had a 'loose' brake line. I found that I was able to maintain centerline and decelerate at a reasonable so); so I simply maintained the required inputs. Given the potential severity of an unexpected brake failure; I would suggest a more thorough review of brake hardware after work is performed on it.
