Self adjuster are to be fully loosened when refit.They are suppose to adjust when you apply the handbrake several times.If not open the lining by leverage with a screwdriver etc at the top where they contact on to the wheel cylinder and you should hear them click.Do one click at a time and keep putting the drum on to see if it is a nice fit i mean that you can just feel the linings touching the drum on rotation.
