On the corner that locks check for shoes contaminated with brake fluid or oil from the axle. I never understood how a lubricant can make them grab but it does. Regarding the need to pump them up make sure the adjusters have the shoes tight to the drums without dragging, if that is good then I'd flush all the fluid, bleed them and see if that gets it. If not then maybe a bad master cylinder.
