My experience real time and in the simulator (737) was that pilots used to using auto brakes for all landings - regardless of length of runway and dry conditions - were all at sea when carrying out a landing using manual braking from the word go. Usually they would jerk from side to side down the runway with uneven braking. What was clear was that they had got out of practice at applying normal braking without automatics. Their hand flying showed similar rusty skills. Quite worrying really when you know the pilots are so reliant on automatics that normal skills are eroded over time.
But I guess that's the way it will always be.
