Never seen this before - Parking Brake Shoe Replacement Help

[cmatt]

176k miles, vehicle specs in sig. @swathdiver @Doubeleive @petethepug and anyone else. A couple weeks ago, I replaced my rear pads and rotors. I noticed the RR parking brake shoe did not have any pad material left on the metal ring. There were no pad material chunks or excessive brake dust. The LR side was fine.





So I ordered parts and set about replacing the parking brake shoes. Got the parts swapped out without issue until I tried to reinstall the RR rotor. The adjustment was all the way in and I was barely able to get it on. Forget about it rotating. What gives? What am I missing? Maybe the last guy removed the pad material so it would fit?

Could be. Try swapping rotors if possible.

I have purchased some parts store brake pads that were just too thick.
Went to another store, material was thinner, everything worked fine.

I know you got the Delco pads, but maybe the rotors were changed before and one was out of spec?

Are you sure the PB cable or linkage is hanging up?

Checked that and seemed good. LR has good clearance and engagement.

I would guess without being able to have a closer look that there is a issue with the parking brake hardware
I am a bit confused by your photos? looks like you replaced a axle and some hardware? can't tell which side is which and what was replaced or not replaced, per side anyway
in any case try measuring both sides and see what's up
the old parking brake shoe does look like it was worn down to nothing but probably happened a long time ago, maybe someone drove it around with the parking brake applied.

It looks like the lining/shoe is too wide in the middle of the shoe, but I also don't like how the ends of the lining seem to be apart from the metal shoe. Maybe too much or lack of adhesive, or the horseshoe is bent? Is the lining the same way on the other side?

In the olden days (LOL) at times we had to arc (so, grind) the linings to match the roundness of the drums. Asbestos was an issue then but I'm not sure it is now with modern materials.

Switch shoes side to side. Switch drums/hats side to side.

Might rotate the disc several times and see where the rub marks are on the little shoes. Maybe a little bit of material removal could free it up. Should have a really good EM brake when done I'd think.
