How do you remove rear brake drum on chev van 2500?

with a brake spoon or 2 flat screw drivers,(1) push the auto adjuster off the star wheel with one screw driver, (2) then rotate the star wheel from top to bottom with the other screw driver, the adjuster lays on the outter side and above the star wheel use a flashlight to see the componets (3) you gain access to the star wheel from the backside of the brake cover by removing the small oval rubber covers. When the star wheel has been rotated several rotations the drum may be tight on the axle, use a piece of wood and then hammer the outer edge of the drum do not hit the drum directly with the hammer it could break the drum.
