Every time I remove the front wheel and reinstall it, it seems like I have to readjust the brake trim screw to recenter the the pads relative to the rim. I would expect that since the skewer is just clamping the fork to the hub which should change from side to side, the rim would reinstall in the exact same position relative to the brake. The other possibility is that the hub is not seating in the fork dropouts in the same position so that wheel is at a slight angle relative to the forks. For that reason I always press down on the front of the bike before tightening the skewer.
This is the case with both of my bikes. Is there something that I'm doing wrong when installing the wheel or is this normal?
