How do you remove rear brake drums on a 2001 Isuzu npr?

Behind the brake caliper plate are to holes. You will see a label that says loosen. Loosen the brake shoes from the drum by pressing in the adjustment wheel locking plate and then spinning the adjusted wheel away from the caliper plate. Only need to spin the adjustment wheel a couple of turns.

On the front side of the drum. Remove the two 14mm bolts that holds the drum on during manufacturing. There are two different holes, on the front of the drum, that have thread. I do not remember the size of the bolt, but the tread is the same size as the first two bolts that were first removed. Take those bolts to the hardware store and get two more like them except they need to be 4inchs long. Thread the bolts into the other two holes and tighten each a little at a time and the hub will slide right off.
