Right rear wheel locking up

[WP29P4A]

I don't see the lower spring that is supposed to go from pad to pad just above the adjuster? Is it missing or just perfectly hidden behind the axle?

I don’t see the bar that goes across with the spring on one side either that goes just above the axle.

I also don’t see a jack stand or pictures at Multiple angles tho.

Terrible.

OP, take that adjuster apart and clean it up and oil/antiseize the threads.
You don’t say if it locks up after the brake pedal is pushed, but most likely the wheel cylinder is corroded. Can test, carefully, have someone depress the brake pedal, a little, you see if the pistons expand like they should and then if you can compress them back in. Don’t crAm on the pedal doing this or you could pop the wheel cylinder apart.
It’s either the adjuster or wheel cyl likely. Or collapsed hose but that would affect both rear brakes.
Just a few ideas.

Parts are cheap though. Personally I’d just buy new hardware and wheel cylinders if I was taking it apart

Everything looks to be in place and correct. Doesn't look like it missing anything that I can see.

Thanks boys except the dude complaining about Jack stands and multiple camera angles. I’ll do some testing.

I would suggest doing the axle seals as well.

id say it needs a spring kit (tired springs), clean and check of the cylinder, lubrication of the metal on metal rubbing places and is that secondary shoe narrower than the primary? like, almost like the metal backing part of the shoe is a different size rear drum shoe unless its optical illusion

Also, that adjuster needs to be cleaned up, lubed, and that park brake cable should be in good adjustment and etc.

Long story short, clean the stuff, lube it with brake lube where rub/pivot/energizes

Make sure adjuster is good, adjust
can you by hand make it rotate as if you were applying it slightly/ Its a little weird but you should be able to, that would tell you if its all "in" properly. you

That oil soaked shoes will do it every time. Need new shoes. And find out where the leak is coming from. Axle seal? Brake cylinder?

Well they got plenty of cobwebs in there- bet they aren't helping.



Getcha can of that "brake parts cleaner" stuff and spray all them brake parts with it , very liberally. It's a couple bucks...

The "backing plate" behind all those parts is intended to be lubricated to some extent in places


Speaking of a COUPLE BUCKS..allthem parts are super cheap as far as car parts go and you really oughta be replacing them all. You can even buy new adjusters!

That's hard to overstate.

I bet you could replace 90% of those rear brakes for a Ben.
Really man, you should change it all out for new stuff.
Measure the inner diameter of your rear drum and take the picture you posted to the parts store.

Buy shoes - the medium option - wheel cylinders , and a master hardware kit aka: a "combi kit" _ but get the big one...options of big and little haha I think its called a master kit. Nobody says combikit anymore..

Add a couple cans of the spray and a dab of bearing grease in the shiny spots, you'll see em after you clean it....i

Be sure to check the tire pressure and for gawds sake man - only take apart one side at a time...it's easy! Might need a pair of dikes.. AND get the drums turned!

They also sell loaded backing plates

Just remove the axle shaft(C clip???) and he wants to do his seal anyway

and then a couple things here and there and bam dorman brakes

Well maybe we oughta slow down...
Dude has no experience and thsts okay- happens to everybody - but we do and talk like it's easy. Because it IS man , OP dude, but that's a LOT of parts and it is important that you put it back together just like it came apart, which is why they stress one side at a time....so you have a handy reference on the ready.
Th tools are extreme basic though everybody does it different , I use 6" dikes to pull the springs and a #2 or 3 flathead. It's not hard to do physically but the motions and movements are uncommon and it can seem strange. Take your time and go slow... Do her up real nice and she'll thank you for it.

i agree I only say the loaded assembly because even tho its more than necessary, it cuts ouyt a lot guess work HOWEVER even just reviewing pics of the product irself(loaded backing plates) will show color coded springs all clean and placed where need to go, only need to review pics posted here to then see the other couple things

GMS diagrams in the service manual only show one side and the exploded view doesnt ddo a good job demonstrating what it looks like "as a whole unit"
