Narrative:

While in cruise flight at 15;000 feet approximately 100 miles out from cocos intersection enroute to aex the captain and I heard a loud bang which we almost immediately suspected was a lightning strike. The captain claimed to have felt a little bit of shock through his feet from the rudder pedals as he was the pilot flying. I felt nothing and only heard the sound. We notified ATC; our flight attendant and the company shortly after. I made a PA to the passengers to notify them of what the noise was and update them of our arrival information.shortly after; ATC queried us as to if we wanted them to 'roll the trucks' as a simple precaution. We agreed. No emergency was [stated]. Everything functioned normally in the aircraft inflight. No abnormal EICAS messages were noted. Upon landing the captain noticed a somewhat lack in steering authority on the ground and braking effectiveness. The airplane was brought to a complete stop on the runway.the captain disengaged the nose wheel steering and then reengaged it and was able to taxi the aircraft normally under its own power to the gate without issue. However; we did notice an abnormal 'popping' sound coming from what seemed to be the nose gear bay. Fire trucks were standing by for us but were not needed. Passengers deplaned normally at the gate and we took appropriate maintenance actions. Only minor scorch marks were noted on the rivets of the nose gear doors.
