To remove the rear drum on a 1996 Kia Sephia, start by ensuring the vehicle is securely lifted and supported on jack stands. Remove the wheel, then locate the drum's retaining screws (if present) and remove them. Use a rubber mallet to gently tap around the drum's edge to loosen it, as it may be stuck due to rust or debris. Once loose, pull the drum straight off the hub; if it doesn't budge, check for any additional retaining clips or adjust the brake shoes inward using the adjuster.

Bang the drum in the direction of the other side of the car, right at the perimeter of the drum while spinning it. The object is to ring it like a bell and vibrate the rust loose, works every time.
