This probably won't help billyjakester anymore, but I just got through the same problem. 24 hours of penetrating oil and tapping my screwdriver with a hammer and nothing. I got my wife's hairdryer and started heating up the caliper. I used a small piece of wood to try to shield the pin plug from the heat, so it wouldn't heat up as fast as the caliper. 2 minutes later, the pin plug was out.

And it wasn't a situation of having been screwed in too tightly, unless Honda did it at the factory. I bought it new, and at 49000 miles, this is the first pad change!

The pin plug goes back in with antiseize!
