I did a brake job a few weeks ago where I installed new rotors and pads myself on the front brakes only. When I was done I noticed the brake pedal had to be depressed about 2" before any braking would be applied, so I took it to the dealer to get the brake fluid changed and bleed out any air that might have been in there. When that was done, the brakes felt perfect - very firm and touchy like they always have been. About a week later and they are right back to where they were, very spongy and I can get the pedal down to the floor just about when the car is running, but not when its off. I'm not losing any brake fluid, the level has stayed steady in the reservoir since having it replaced at the dealer. Is there anything else I should check or replace to fix this?

Its an '06 Honda Accord EX v-6 with about 92K on it.
