that is a very good tip to try without the wheel .. well it is quite dark here now and temperatures are dropping around 32F so i have to give this another try tomorrow again.. i will take the jeep around the block later on tonight when im off my shift and see how that sounds . i hope that goes well.. i will let you know tomorrow again .. taking off the shoes and trying the drum without a wheel should indeed give a total picture of what is wrong .. thanks again ezearl , marc
took the jeep for a short ride but sounds horrible drove about 40 feet and parked it back. thinking about it more i will purchase a brandnew set of shoes aswell and do the job right.. i did open the bleeder screw on the wheel cyclinder thinking that would retract the shoes completely, as of now i will put the old drum back on and wait for the parking brake cable to come in and buy the shoes aswell do it all at once.
The return springs (if in good condition) should have no problem retracting the shoes completely. Is the flexible rear brake line collapsed? When you install the brake drum and wheel on the axle and tighten the lug nuts can you spin the tire to see if the drum is jammed up against the backing plate or binding on the brake shoes?
didnt get to do much yesterday but today i took the new drum off the jeep and noticed scratches in the new drum as you can see in the pictures. ive doubled checked if the brake shoes are retracted and it does seem like it, the adjuster on the bottom of the brake shoes assembly is as lose as it can if i make it any shorter it would just plain fall out so it is a tiny bit unscrewed to make it longer. so clearly it seem like the shoes are rubbing into the new brake drum and for what i see so far not rubbing on the backing plate as i thought before.
now ive put the old drum back on and i had to adjust the adjuster quite a bit to get it just right. so my guess is either the new brake drum is too small or the brake shoes are too thick eventho they are worn a bit already and still rubbing on the new drum..
im not sure where to go from here.
keep in mind i dont have a lot of time to do this and its 25F outthere and i do this quick had no feeling in my thumbs left lol

[edit] the return springs have all been replaced last summer and are in good condition

The adjuster should not fall out fully closed. Either that bottom spring that runs horizontal behind is gone or your ebrake cable is not letting the ebrake arm relax. I had an ebrake cable do that just a while ago, cable was froze and would'nt retract. Either way the adjuster can close all the way and not fall out. Pics are not close enough to see your bottom half setup for me to tell anyways.
Ohh, and get a tape measure out for those drums, only way to know if they're the same.
Comparing DJ's pic to yours, the ebrake arm could go to the left more. Have someone operate ebrake while you watch for function at wheel. The spring looks like it is attached properly.
Note from DJ
I think this information is OK
10 inch inside diameter brake drums are fined on the outside and take 10”X 1.75” wide shews.
9 inch inside diameter brake drums are not fined on the outside and take 9”X 2.5” wide shews.
i had a quick peek underneath the jeep today, i see one place to adjust the emergency brake lever right in the middle of the jeep where to two parking brake cables come together, i see a nut that tightens two cables at once. the nut is screwed on there quite a bit so i have enough room to release the tension right there. do i see this right or is there another spot to adjust this ? ... i followed the parking brake cable to the passenger side and it goes in to the backing plate i dont see any other way to adjust this anywhere else. will have to wait till monday now to do this tho.
That's your equalizer and is the only way to adjust the parking brake. I'd PB Blaster that nut and back it off until there is a good bit of slack in the cables. You can then work the cables by hand to check for free movement of the parking brake parts.
Before you try installing the brake drums have a look at how the brake shoes fit around the anchor pin. They need to fit nice and tight like the photo. The reason being there was a problem with some of the 9in shoes where the ark in the shoes was too small which made the shoes too big for the drums; but so far no problem with 10in drums.
Please keep us posted if you need more advice, or we hope that you can report all is working OK.
the moment of tightening the lug nuts the wheel cannot be turned by hand its really tight.. seems like the tighter the lug nuts go the tigher the wheel is
From your pics, it looks like you set up all the springs correctly, and you can see that the shoes are pulled inwards, away from the rotor, so I don't think its an adjustment issue.
The fact that you can fit the brake drum onto the assembly with shoes installed means that the braking surfaces are probably not rubbing too much.
From what you said, it seems like either:
1. The brake drum is rubbing on the backing plate, or
2. More likely, the shoes are too wide for the drum and the inner brake drum non-braking face is rubbing on the outward metal parts of the shoes, the parts that are facing out towards you when the brake drum is off.
What if you remove the shoes and install the brake drum and tighten the lug nuts. Does the wheel turn? If so, its probably not hitting the backing plate. (sorry if i'm repeating something you already did).
It really seems though that the shoes may be a bit too wide. What if you cover the edges of the shoes with marker or paint and then put the drum on, put the wheels on and tighten them to where they bind, but still turn. Turn the wheel a few turns. Then take the drum off and see if any paint rubbed off the edges of the shoes - that's where they are rubbing.
You might just need new shoes - but narrower than you have now, or a wider drum. You could just bring your parts to Oreilly's and compare them to what they have, for both drums and shoes.
It may not be obvious just comparing visually - it seems like your shoes or drum may just be off by a millimeter or so.
