 Subject: '93 Dakota loud brakes

OK, I have posted this on here before, but I thought I would ask again to get some more opinions before I take the truck to the shop.
I have a '93 Dakota 3.9L AT 4x4 and it has 177,000 miles on it. I purchased the truck probably 6 or 7 years ago with 127,000 miles on it and right after I got it home, the rear brakes were making a grinding sound. So, I pulled the rear drums off and on one side, the shoes were cracked and falling apart. So, I bought new drums and shoes. I am not sure I did the brake cylinders, but I think I did. That seemed to fix it for a while, but for the last couple years in the cold of winter or in a cold damp rainy day, the rear brakes howl when applied at lower speeds. I had it taken to a couple shops in the last couple years and one told me it was the parking brake locking on even though I don't use it. They just freed it and it was fine for a while. Then it came back so I took it to another shop. They also said it was the parking brake even though I made a point this time of not using it. So, they just removed the parking brake all together and also re-did the drums and put new shoes on it again. Well, that was this past summer and now this winter, they are howling like crazy again. The guy at the last shop told me that some Chrysler product brakes just make noise, but I don't believe that it would be this noise.
So, here is when the noise happens. It happens in damp weather. It can be raining and cold out and they will do it, or it can be cold and snowy and they will do it. It happens especially after it has sat for a few hours, but not all the time. It doesn't necessarily happen at every stop either. It can happen for a few stops, then it will go away for the next few, and then come back for the next few again. It doesn't happen until right before coming to a stop, so maybe under 15 mph.
One thing I noticed this morning in particular is that we got a lot of snow yesterday and my truck sat from Tuesday afternoon til this morning without moving outside. I went to leave the driveway and it felt like they weren't applying at all in the rear. So, I put my foot down harder and they seemed to apply then. They howled coming to a stop again. Then, when I went to take off, I let off the brake and hit the gas and the brakes were howling for a little while without the brakes being applied. Like I had locked them up and they weren't releasing. Eventually that sound went away while driving.
So, sorry this is so long, but I would like some opinions on this before I take it to a different shop and see what they think. The drums and shoes are new, so I wouldn't think that would be a problem. There is no parking brake anymore, so that must not be it. Could it have something to do with the brake cylinders or worse, the master cylinder or proportioning valve? Does this truck have some kind of rear wheel antilock system?
Thanks for your help in advance.

Did you replace the hardware too, like the springs that retract the brakes ? And lubricate hardware contact areas with antiseize ?
Lead, follow, or get out of the way

Yes, I did all of those things when I replaced the brakes the first time. I figured I should replace that stuff at the same time.

One other thing that I can add to this is that this winter, we have had a lot of snow and one of the streets on my route to work is always snow covered and really slippery. I try to come to a stop and I start sliding; not a big deal, but when I do finally come to a stop, if I have my foot maybe half pressure down on the brake pedal, the rear wheel(s) are still spinning on the slippery snow. I really have to mash down on the pedal to get them to stop spinning, and this is at a complete stop. Is this weird or not? Then, after having to mash on the brakes to get the rear to stop, when I go to take off again, it feels like the rear brakes are locked on. Then the issue comes into play like I mentioned in my first post where they make noise while moving without my foot on the brakes until I get down the road a ways, then they stop until the next stop.
This issue seems to be somewhat intermittant, so I am really quite puzzled as to what it is.
So, if anyone has any other helpful hints, I would really appreciate it.

What about the rear rubber hose? It could be swelled which could explain the increased pedal effort to stop as well as the rear brakes not releasing completely.

What rubber hose are you talking about? Where is it located?
Thanks

You most likely have water where it doesn't belong. It freezes, and keeps the brakes from working correctly. It's probably in the brake cylinder. I'd take those apart and rebuild them; or just replace them.

In the brake cylinders at the wheels? Those should be replaced then you think? I am not sure that the only time it happens though is when it is below freezing. Sometimes, it happens when its cool and damp, but not below freezing. Could water in the lines still be causing the problem even if it isn't freezing.
Thanks again.

I was refering to the hose that runs from the frame to the rear diff where its splits and goes to the left and right wheels.

My 96 does the same exact thing besides making the sound after letting off the brakes. Mine is random as hell, seems to do it more when it's wet out side. Also one of my shoes is cracked, and I have been meaning to get that taken care of. Just so cold and snowy lately.
Honestly it sounds like your shoes or drum might be worn. Yes I know they are very new but, if they seem to stick that often that would wear them out fast. Sticking shoes usually is due to bad wheel cylinders, or some kind of bind mechanically. (could be full of snow or frozen also)

After thinking about it some, I didn't replace the wheel cylinders when I redid the brakes. I thought for sure at least one of the two shops I took it to for the problem might have suggested the wheel cylinders if that was it. I may take the truck in and have the whole brake system redone again. I need a parking brake put back on anyway.
Thanks everyone.
