I have a 1999 Dodge Caravan and was in the process of replacing the front disk brake pads and the back brakes shoes. I did not have any problem with the front brakes but when I tried to remove the aft drum is where the problem began. Its been many years since I have done this but as I remember you always had an adjustment that you could make to the shoes to adjust them in so you could get the durm off. On the caravan I cannot find this adjustment. I cannot get the drum off. Do you know another way to get the drum off? The drums starts to come off but hangs up at about an 1/4" of movement both sides. I think the drum might have a small lip worn into the drum causing them to hang up on the shoes. Where is the adjustment for drawing the shoes in for this promblem?

Thanks,
