Sounds like you need to pull both front drums and check to see if the primary and secondary shoes are installed correctly.
Then when reinstalling the drums, adjust the shoes in-out so there is equal drag side to side. Pushing on the brake pedal with the drums on, wheels off, will center each set of shoes in the drum. Rotate each drum and using feel and sound, adjust one or the other until they seem equal. A good starting point is to adjust so you can just barely slip the drum on.
IF the self adjusters are working properly, the proper adjustment will be maintained as the shoes wear. They are automatically adjusted when the brakes are applied going in reverse. You can go to a parking lot, back up, apply the brakes and stop. Repeating this several times should fine tune them. IF everything is working right.
Having said all that, drum brakes tend to be grabby anyway due to the self energizing feature. That is why the primary and secondary orientation is so important.
