brake help

[canonball]

Ok this is what I'm starting with, the first photo is the front and the second is the rear, there's a couple of screws on the fronts (one near the top-right and the other near the bottom-left). Do these need to come out to get the drum off? and for the rears do I just bang them with a hammer til they come loose?


p.s. photos are flipped on their side for some reason. just flip your moniter on its side.
