I assume you have rear drum breaks and replaced the springs. Their is an adjuster for the shoes. They have a brake adjuster tool with a rubber plug you remove for axcess gradually tighten it until the shoes barely rub the drum.
If this is good pull the drum on the otherside and make sure all parts are installed the same.
If you drained the system you might to pressure bleed or go to a shop with a scanner to properly bleed. Try shoe adjustment first.
