Hy Saw Mill, the first order of business is to back off the brake adjustments on all drums, hopefully the adjusters will allow you to do that. To remove the front drums from their hubs you will have to remove them as a unit so that you can get to the heads of the bolts which hold the two pieces together. The rear drums can technically be removed without removing the hub, but that may prove to be harder than removing them with their hubs. There are three countersunk screws in the face of the drum that can be seen once the wheels are removed and the drum surface is cleaned up, you will probably need an impact driver of some sort to get them out, good luck
