Narrative:

Maintenance controller called us at ZZZ and reported that air carrier X inbound flight had received a #4 brake replacement at ZZZ1. B757 brake installation requires an rii (required FAA inspection item) inspection. Technician notified ZZZ that a confirmation check was accomplished; not an rii. Air carrier X would be grounded until an rii inspection of #4 brake installation was accomplished. Inspected #4 main brake assembly per maintenance manual 32-41-10-4 and gpm section 18-01; appendix a chapter 32; paragraph 1F. Apparently the mechanic that originally performed the rii inspection was or is not rii qualified; requiring a re-inspection of the #4 brake rod installation.
