i had the same problem and its not the caliper its the piston that is attached to the brake pedal from the booster that pushes the master cylinder you clearance is off and you need to get it checked.

ps. only honda was willing to fuck with mine to get it right


I found a site that tells you how to adjust it on the fly but it is going to take some time to get it right. Honda designed it so only they could easily work on it.
