Rear Drums Sticking

Hey guys,

So I was messing around yesterday installing 3 degree shims when I noticed my rear hubs/axle not spinning how I anticipated. After a little further look, it seems like my drums are dragging. Spinning the axle 360 degrees, it spins freely for about 180 degrees followed by a sudden onset of resistance for the rest of the rotation. The video should help clarify.

I have an appointment with Toyota on Wednesday for a diagnosis. I've experienced issues after rain or car washes where the rear drums lock up after parking brake engagement and "slip" during hard braking. Not impressed with the rear drums, Mr. Sweers.

Drum warp? Doesnt seem terrible. Sticky spring maybe. idk

 

Very likely. I guess I'm just wondering how worried I should be driving around, causing premature wear. Although I've probably been driving on it like this for a while without knowing.
