Not sure what you mean by balancing?
Adjusting is not technically difficult but can sometimes be a bit of a PITA. Disk brakes by design drag just a bit. Drum brakes should be adjusted to where they drag slightly and then backed off just to where there is no drag. Generally, the final adjustment is made after everything is back together by backing up and applying brakes sharply several times.
One other caution: note that the length of the lining is different on the front and rear shoes.
