The remark about brakes not holding long enough is very clear to me. Most pilots I've ever seen on different types flew with too much speed reserve, too much head/crosswind correction and keeping power/thrust for too long. This increases landing distance by a great margin. The inproper technique doesn't end there, since a big group of pilots doesn't have a concept about proper braking technique and use of reversers.
Other than that, I agree that it's type specific. The only common values are:
at 50ft starts your landing
you have to be over the threshold.
you should have Vref (or Vapp or whatever your manufactor calls it)
flare: reducing vertical speed and reducing power/thrust should go hand in hand (there might be exceptions with very strong winds, glide angles or runway slopes)
Latest at the ground you should be at idle
Since we are also talking about Airbusses, I see too many pilots keeping the thrust for too long, leading to an increase of thrust during the flare and increasing the landing distance, using too much braking/reversers.
