2002 Dodge Caravan can not remove drums

Hello, there may be a brake adjustment slot on the back side, it may have a rubber plug in it, remove the plug and use an adjustment spoon, to take the tension off the brake shoes, where applicable.

Have you tried a BDH, (big darn hammer) tap around on the drum a little, maybe knock some rust loose.

There may be a couple of threaded holes in the drum, you screw in a couple of bolts, the bolts press up against the hub, forcing the drum off. M8X1.25MM bolts
