front drum brake stuck

Did you back off the adjuster? It can be done with a flat head screwdriver but is best with a brake tool. Keep in mind that if the brakes have seen some use, there is probably a lip on the edge of the friction surface that will prevent the drum from pulling off easily. In fact, it probably shouldn't pull off easily. After loosening the adjuster, give it a couple decent raps with a hammer and it should start to come off.
