Ended up taking the car to my tech. Checked the brakes. Turns out the brakes are fine - dry as a bone and everything operating as it should. I'm guessing that perhaps a little bit of fluid was forced out when I compressed the caliper fully - or maybe it was even water, as suggested, since we had some heavy rain prior to my doing the brakes.

The pulling ended up being caused by a bad ball joint. Replaced that and my car is riding like new and braking smoothly.

Thanks again for the input.
