How many miles has it been doing this ? Many times water will pool in the drum and rust, takes time but after some miles of braking the rust is worn off and things go back to normal.
Warping those drums takes a lot of heat, did you smoke the brakes very badly?
Plus once you see the price for those drums,
you may decide to wait and see if it goes away; or look into turning the drums to true them up.
