It gets stuck and does not revert to the standard position. Does this have to do with the spring, or is there a different problem? (Pic shows it in stuck position)

The brake shoes are likely just all rusted and dirty. I think if you take the drum off and clean or replace the brake shoes as needed, all will be fine.

The return spring over the shaft(cam) could have popped out or broken. If I had to put money on it I'd say the shaft wants removing, cleaning up and greasing, looks very dry and dusty down there.
Personally I'd strip the whole assembly, clean up, lube appropriately and reassemble, usually does the trick.

I'll do a full disassembly then. I needed a jack+stands for my car anyway. Thanks for the help guys.

sticky or frozen brakes tend to be from yrs of lack of care and cleaning, your brakes should be clean every so often, if not they get gummed up and if left go too long will be a royal pain to get working again
them dust seals and such are not perfect to keeping crap out!

I think Sam nailed it , the shaft is sticking in the backing plate , take it out and polish it with emery paper , there are seals on the shaft , replace them and apply your choice of never-seize , grease or I like to use multi-purpose marine grease

Maybe I will pay that area on the bike more attention with the power washer lol. Can you guys tell me what I'm looking for here? Sorry I'm a bit inept. I assume #8 is the shaft you speak of, but what is the backing plate? Diagram attached below.

The backing plate is the large part that the shaft (#8 as you guessed) goes into... number 4 on your photo.

Be careful directing a high pressure power washer nozzle at shaft seals and wiring harness plugs. You can force water into them quite easily close up. Back up, slow down and rinse the mud and dirt off... don't ever blast the bike.

Have fun,

I finally got around to the disassembly and the whole thing is gross! Mud, water, gunk, you name it. I plan on giving everything a thorough cleaning with brake cleaner, rags, water, and emery paper. Before I put it back together, what pieces do I need to grease? I got a multi purpose marine grease on the recommendation of fishfiles. Pics attached.

 

[SamUK]

Grease everything that moves apart from the obvious, the drum and friction material on the brake shoes.
You need to remove the shaft from the backing plate, that's the bit that has the lever on and your cables connect to, that will want a thorough cleaning and a good dose of grease.

Alright guys, I've worked a little more so I have more noob questions (please bear with me).

1. What is the easiest way to get the circlip out?
2. How do you get the big dust seal out of the drum cover?

Pics attached and many thanks to you guys for helping.

Circlip pliers for the circlip, you can buy a set of internal and externals off eBay for about $15.
The seal.... Usually seals are a use once item, it's probably worn out and will more than likely no good to reuse once you have it out. Best option is to order a new one, again it will be relatively cheap.

Edit: To remove the seal, pry it gently with a screwdriver or an awl, be sure not to damage the seat (area where the seal fits) when poking around with a screwdriver.
You can also screw a self tapping screw into the side of a seal and then attach vice grips and pull, usually the safest option if your in any doubt about slipping with an awl etc

I tried doing to light poking/prying with a screwdriver and it wouldn't budge. Should I be prying from the inside or outside of the drum cover?

you need a pair of snap ring pliers to get the snap ring out, and just tap the seal out from the inside outwards, that's how its done. make sure to have a new one on hand BEFORE you remove the old seal !.

Hey guys, where does the ring clip go on this drum? The Partzilla diagram isn't very clear and it didnt even have one when I took the brakes apart (??). I put it on the outside, but I bet that isn't right. There is no obvious groove.

What are you working on?

rancher 420 rear brakes.

big rings like that are always installed in the inside of most rear brake drums.

 

[shadetree]

if ya look up the break down of your rear brakes, you will see that big ring. you can't service these !, they are made into the brake drum !.
