Just to asage your fears, I have over 2100 miles and I haven't noticed any excessive accumulation of brake dust, though my experience has always been that brake dust will accumulate faster in the first month after new pads (which these would obviously be) are installed. Of course, I have already washed my Pilot about 3 or 4 times and the first time was within the first week I had it (got it pretty muddy on a fly-fishing trip). I suspect that the problem is as Cheesehead pointed out or because of the newness of the pads.
