You can try the following:

Remove the front wheels & unbolt the calipers....Remove the disks & wire brush the axle hub (where the disk mounts up) and also wire brush the inside of the disk hat where it meets the hub & then reassemble...Ensure to tighten the wheel nuts opposite to opposite to get them even.
