Rear shoe replacement questions

[RutherfordmanX]

I need to replace my rear shoes on my Yaris. I think I let them go too long this time (yes I hear a noise unfortunately). I have done this once already with no issue but I have a stubborn drum this time to get off and I don't want to break anything trying to get it off. Can you access an adjuster thru the backing plate and loosen the shoes prior to removing the drum? If so which way do you turn the adjuster to loosen? Not sure if the Yaris has this feature and I am afraid my shoes have worn to the point where there is a lip which may make it difficult to get the drum off or/and the drum is rusted on. I have the correct bolts to thread into the drum that back it off but once again I don't want to force it and break anything. At over 300,000 miles things in there may be getting worn (you think?) Any other words of wisdom on the rear drum brake job would be appreciated. It has been awhile since I have pulled them off and I may have forgotten something (old timers disease you know). Thanks for the help!
