If you are using quick release scewers, rubbing can be an issue everytime you remove and replace the wheel. ( my bike rides in the back of my pickup in a delta scewer so I remove the front wheel often ) Try this! Loosen the mounting bolts for the caliper and the ISO adapters " if you use them" With all the bolts slightly loose squeeze the brake lever and watch the caliper adjust itself, while still holding the brake lever in tighten the mounting bolts just enough to hold the caliper in place. release the brake and spin the wheel and check for rubbing. if it still rubs remove and reinstall the wheel and repeat the procedure. Good luck!
PS. Don't forget to torque the bolts once you have evrything aligned!
