    Rear Brake Job

    Well yesterday we got a bunch of snow here in Vermont, so it was a great day to work on the Wagon in the heated garage. It's been sitting in there since the fall as I didn't intend to drive it this winter until I was able to undercoat/protect the under side from the damage that road salt will do.

    After finally replacing the starter (I have been hunting and fighting intermittent starting issues for a few months) I can now finally get around to replacing both the rear wheel brake cylinders. But I figured, while I got the whole thing apart, I might as well clean it all up too.
    Hope you all enjoy the pictures, I'm about half way done, I plan to prime and paint most of the parts that I cleaned up. The difference between the clean and dirty backing plate bolts I think says it all. Pretty much everything metal has been getting it's turn on the wire wheel.

    I do have some questions, are there any things that I shouldn't paint? I know to leave the brake shoes alone (other than cleaning out those spider web egg sack things) but not so sure what else, especially when it comes to the axle parts.
    I cleaned up the outside of, what I think is called, the outer oil seal, but as seen in the pictures there is a bearing or washer inside. Do I dare mess with this? I am trying to clean up and protect anything that I come across, piece by piece as I get the Jeep up to standard. Also there are what are maybe shims? there is one that is definitely a 1/8 inch metal ring, but the others don't seem to be, are they gaskets? With the metal rim and oil seal on opposite sides of the backing plate? Seems to be a gasket on the back of the oil seal too, I would imagine I should replace these. Would it be 3 per side?

    Thanks again for putting up with all my questions, it is you guys on here that are keeping me on track.

    Few more shots of the road grime and crud that I have been dealing with and trying to clean up as I go.

    Try to keep as much of the old hardware as you can. It is a better grade of steel than much of today's, even if they are the same "grade".

    If you have access to a case tumbler (rifle/pistol cases) that uses stainless pins as a steel tumbling medium, it cleans things up very nicely!

    VT,

    As far as refinishing brake parts, a good rule of thumb is that if it is in contact with the outside environment, then paint as you please.
    I whole heartedly agree with LarrBeard on the reuse of the original hardware, that stuff is a lot tougher than anything you can buy on the market today. It's all made with real steel.

    VT, the real seal outer is "unitized". It is a seal integrated into the seal cover. It looks like this:

    Yours is cleaned up nicely but, no good. it is missing the seal.

    Here is a look at the parts you are working on.

    There are shims that control the end play of the axle. The service manual does a great job of walking you through the set up of the bearings and the rebuilding of the wheel ends. I definitely recommend a copy of the manual to help you through.

    Alright, I will mention that to my friend's uncle for the '48 Willy's he's looking at. I'm coming over to their garage this weekend for the re-painting and installation of the new wheels and tires from 4Wheelonline onto my friend's truck. I'll see if his uncle already has the Jeep.

    Well, I figured out where my mis-understanding was. Because they were stuck together, I thought the outer oil seal and the outer grease protector were 1 item. (Left and Center in below picture respectively)
    After getting the new outer oil seal in the mail, I was able to get a better idea how it all goes back together. At closer look at the diagram, the Grease protector looks to be in the picture, but is listed as #35 with the oil seal, and then is not listed to be purchased down below.

    So, the good news is I figured it out, and now can get everything back correctly. Bad news is, since I didn't know it was 2 parts, I need to order an additional gasket. No big deal, I'll use the gasket out of the other oil seal I got for the driver side since it will be a week or so until I can get that side started.

    With the Vermont snow mostly gone, I can't wait to get the Wagon back on the road, Hopefully this summer I will be able to get the underside cleaned and coated enough that I am comfortable driving it next winter (the salt on the roads here literally eats unprotected cars).

    I see, well, I think I see. I did plan on keeping as much original as possible if it was able to be cleaned up, mostly because that is the cheaper option, haha,
    As far as the seal goes, isn't that the inside ring part in the picture below? I was skeptical about what it was and didn't want to take it out and risk damaging it at all.

    If that is not it, then I am kind of confused again.

    I have noticed that some of what I THOUGHT were gaskets are actually really thin metal spacers, so I will clean those up with a rag and a little degreaser and call that good. but I would like to knock the rust off the inside of that oil seal and repaint it.
    If that isn't the seal on there do I keep the metal part when I order the seal that you linked to? or is it part of that kit?

    Thanks for indulging my ignorance when it comes to some of this stuff

    Yes that is the outer seal in your hand, don't reuse it. It comes with all the pieces you need if you order the part from KW on the first link I sent prior. I think that is the one for your Wagon. Look on the other link in that post, you are working on Item 35. It comes with all you need, including a new cover. There is also an inner seal. The shims need to be set to the correct axle end play. You don't really know how many you will need till you check it. If you are careful and the shims are in good shape (don't mix them from side to side). Clean them up and reinstall them from where they came off. If you haven't changed any axle shafts and things other than the brake job, It will be close. New bearings need to be checked and reset. Tight is not good, a little is all it needs and too much causes other problems. If you haven't set the end play on this type of axle before, the manual is a must have.
