72 Supreme. Pax side. With this orientation I am having problems with the actuating link holding the adjustment lever tight enough against the adjustment screw star. The screw just will rotate freely in both directions without engaging the star teeth. I can pull the link tighter to what looks like the correct position but then when I release it goes back to not correct. ( can this link enlarge over time? ). Driver side is working with this same set up.
The Drum tutorial is different on pax v driver side as far as the actuating link and spring order against the shoe guide where both attach at top ?? I tried both ways but neither is working. Thanks.
Thanks Joe.
Is the last picture in the Drum Brake sticky correct? It looks like the spring is behind the lever on that one?
tried to post that pic but says file is too large.
Thanks Joe.

Yeah, that's not correct. To be honest I've never looked at that thread before. The earlier picture is correct. You'll also notice that the "before" picture shows the spring on top of the link.
Ok thanks. I switched mine to the proper location but still have too much play for the adjuster to engage the star wheel. I’m thinking I might buy a new adjuster with teeth that are not worn so much.

Your problem is the spring at the bottom above the star wheel. It needs to be flipped over so that the part behind the adjuster lever is behind the rear shoe.
Looks like this is the wrong spring.?? It does not have the angle like other picture to not interfere with the star. Should I look for a different spring.

Those springs are RH/LH. What does the one on the other side look like?
I
It is white. And also oriented wrong according to other post. However in this position it does clear the star and allows for what I think is proper operation. ( clicks in one direction and will not move in the other ). This is the driver side.
They look like the ones in this Raybestos kit. The white one should be on the passenger side, red on the driver side. The pigtail of the spring that passes over the star wheel needs to be oriented up, away from the star wheel, and behind the rear shoe so it won't interfere with the adjuster lever. It also looks like the pigtail on your red spring has been tweaked, so that won't help.
Also, did the kit you used come with both long and short hold down pins for the shoes? I assume you used the short ones, right? The long ones are for the wider Vista Cruiser rear brakes.
Joe. Thank you so much. I think that explains it. I actually did not buy a kit , was just inspecting at this point and noticed that there was an issue with the adjusters. Gotta order in for the kit now. Good thing out of this is for as many times as I assembled, re assembled my drum brake knowledge is up to speed. Except when you find an error in the assembly in the first place. !!
Flip/roll the red spring over so that there is a gap between the spring wire and the starwheel.
That's how this whole thread started. Go look at the first pictures. Unfortunately to do that the pigtail needs to be in front of the adjuster link, which holds the link off of the star wheel. This is why those springs are RH/LH and are different colors.
New adjuster springs are going to fit the way they are suppose to….!, before I assemble everything back up I’m not sure where this washer is suppose to go. I did not fall off , that I know of when I dis assembled. Thought it might be the washer for the star adjuster screw, but it’s too small ……
The washers go over the forward retainer pins (on top of the forward shoe) before you put the retainer spring on. That's the spring with the reduced coil diameter.
EDIT: Too funny! While I was verifying my wording was clear, Joe beat me to the punch!
That washer goes under the green retaining spring for the "leading" brake shoe, the shoe toward the front of the vehicle, one on driver side, one on passenger side. Note that the green springs have a tighter coil at one end. That is the end that goes toward the shoe and rests on this washer.
The cupped "top hat" washers go in the hole on the primary shoe, under the yellow retaining spring. The "top hat" washer "ties together," or links, the shoe and the adjuster rod.

To clarify, the trailing shoe is the secondary, not the primary. The top hat washer is the pivot for the adjuster actuator link.
Soooo. Looks like I have pretty hardware now but, the same problem still exists. The adjustment lever “springs “ up out of position so it does not make contact with the star wheel.. I can hold the lever down into position and it will work properly, click in one direction, and lock to prevent movement in the other. As soon as I release the lever it springs up slightly to not be in contact with star anymore.
I bought a new adjustment lever kit thinking that the hook at the top ( now purple) might tighten things up to hold the lever down tighter against the star. It did not.
I read somewhere that the parking brake might be in play, somehow? Then again somewhere else said it should not matter for the self adjustment operation.

If the only "issue" is the arm is not touching the star wheel, then I don't think there is actually a problem. My understanding is when the vehicle is moving backwards (this is critical), the arm will move downwards when the brakes are applied, and this is what turns (and tightens) the adjuster.
The potential “ issue” comes from the fact that normally when manually adjusting, you can hear clicks as the pads are expanding. And if the pads are too tight , you have to get a second screw diver and hold the adjuster off the star to loosen the pads. ( technique to get a stuck drum off as well). At least that is my understanding and what I have been told. It been a long time since I have played with drum brakes, and then I was just watching my brother.
The shoes are designed to move around on the backing plate to follow the drum. This is how the self adjuster works - that motion is what moves the link. If they are not centered exactly, the adjuster linkage will appear to be mis-adjusted. Put the drums back on, adjust the brakes, and apply the brakes a few times, then look at the adjuster link again. I suspect it will be fine.
