My passenger-side front brake caliper isn't releasing fully and it drags on the rotor a little. It doesn't drag enough to make the roadster pull to that side, but there is slight resistance to rolling.
Also, after diving the car a dozen miles or so, that wheel is hotter than the driver-side wheel.

I've removed the caliper and cleaned and lubed the mounting pins and surfaces but the problem hasn't gone away.

Build specifics:
2001 Mustang GT hydraboost master cylinder and hydraboost unit
2001 Mustang GT brakes (the PBR calipers). Donor had ~46k miles.
New pads installed when I built the roadster. The roadster has 13k miles and there have been no issues with the brakes prior to this.

Any thoughts on what could cause this dragging?
