    Again What kind of brakes. Brand, model, type. All of them have different ways to get fixed. Surely you just took the wheel off and put it back on.

    For Avid Mechanicals, just move the red knobs on each side on the caliper.

    For other brakes you need to tell what kind of brake is it.

    A few things or a combination of all of them can lead to some rotor rub (assuming the pistons aren't pushed out too far to begin with). Make sure your wheel is straight in the dropouts. Find somewhere where you can see the rotor/pad interface while the wheel is spinnning. If rotor is mostly centered between the pads but has a spot where it bends to hit the pad, then pull out the adjustable wrench and true the rotor. If the caliper is off center and constanctly dragging on one side of the rotor, then unscrew the caliper and do some fine tune positioning until it's perfectly centered.
