You just described the rubbing/dragging perfectly, Revel. It, indeed, ever so slightly pull to the right.
Now it is sounding like a sticky caliper. Usually, in the beginning, a sticky caliper will show up after driving and braking after everything heats up. It will exhibit as a steering pull to the right (if right-side caliper) while driving, and a pull to the left while braking. My best guess is an issue with the right front caliper related to the caliper work done in the fall. Also, a sticky caliper will cause the rotor to heat up to almost red hot. If you could stand next to it you can feel the heat coming off of it (don’t touch it! You’ll get a blister!) It will also stink.
Is there snow on the ground where you are?
