Narrative:

The aircraft for this flight had a placard on the anti-skid system. One of the requirements of this MEL is that main wheel brakes are operative. Under the maintenance procedures for this MEL is that maintenance deactivate the affected brakes. Although MEL for brakes was not on placard on this flight, it says cannot depart the us mainland. I complied with everything required of me for the MEL that was issued for this aircraft, but should MEL for brakes have been issued along with anti-skid?
