Rear brake adjust wedge removal

[Aok]

Have a problem with the rear brake adjuster wedge it turns but does not seem to click in like the other side not sure if its the wedge or the threads, rest of the brakes look good.
Do I have to remove the shoes can I just remove the wedge.

2nd question to remove the entire rear brake unit after I remove the 4 bolts that hold the housing do I also need to remove the arms that the brake rod connect to. I have the em brake shoe off and 4 bolts loose but it seems like the arms that connect to the brake rod will also need to come off. Was reading the les andrews book and it just said remobe the 4 bolts but the arms seem to hang up

Answer to 1) You can remove the wedge without removing the shoes-BUT it is difficult to replace it without removing the shoes. (two good pry bars can help do this by stretching the rear pull-off spring sufficient to snick in the brake shoes)
Answer to 2) You cannot remove the emergency brake unit without removing the arm first. In fact if you need to remove the entire brake unit ( emergency brakes complete with service brake ) it is often easiest to remove the back plate in its entirety complete with arms and then dismantle it all .on the bench
