You loosened the bearings when you took the brake arm off. Just remove the wheel and retighten the nuts that hold them in place. Common mistake is tightening the wheel before the brake is attached to the frame. After you retighten the bearings set the wheel in place then mount the break arm. If you tighten the wheel first then move the brake arm into place it will loosen the bearings.
