Brake adjustment does not, and cannot cause a pull, since none of the brakes do any stopping until all the brakes are in firm contact with the drums. Look for a restriction in a flex line or a wheel cylinder on the side AWAY from the direction of the pull. That allows the affected brake to delay application while the others are already having a stopping effect. Flex lines that collapse on the inside and restrict fluid flow are the most common culprit.
