Hi guys,

Took a road trip recently, and after several hundred miles, the 'burb was just coated with road grime and road salt (Which they use a LOT of up in Canada!) as we have had a lot of ice and snow up this way.

I came home and gave the 'burb a nice sudsy bath, and rinsed the undercarriage as much as I could with the garden hose.

After that, I put her in the heated garage to dry out for a couple of days.

Today I started her up, and put her in reverse to get out of the garage. Surprise! She won't budge. She's stuck fast. Seriously, I'm in reverse, revving the engine, and NOTHING is happening. I check to ensure the parking brake is not on, and that she really is in gear, and WOW, she's stuck fast. I sat there thinking... I know what's happened! The rotors are rusted to the pads, OR the drums are rusted to the shoes (more likely)!

Well, she really wouldn't budge, so I end up putting her in 4WD-H, and then finally 4WD-L, and she starts to crawl backwards, with a LOT of complaining, mind you. It appears that two of the wheels have broken free, and the two others have NOT. I'm guessing the front two are pushing, and the rear shoes are just LOCKED.

I end up screetching and 'scuttling' her backwards out of the garage, with the drums stuck fast. I keep creeping her backwards, and the drums seems like they are starting to turn. My son comes out to see why I am revving the engine and creating quite the cloud of diesel smoke. I finally get her far enough back to put her in Drive, and it goes hopping down the drive. After about 20 feet, I hear a loud "pop", and both rear wheels break free.

It drives normally after that. Took her out (gingerly for the first few miles) and it all seems back to normal.

Wow. I've never encountered this before.

I'll probably pull the wheels off and check the brakes to ensure everything is copacetic.

Has this happened to you before?

Can't say I've had it happen like you describe. Did you set your ebrake in the garage? My rule of thumb in the wintertime is that far left pedal is to be avoided at all costs.

I don't wash vehicles when it's below freezing, but you said you had a heated garage so that should negate that problem.
 
Coule be the rubber hose above the differential. When they get old a piece inside will hang out like a check valve, it will let pressure in but not out. I wouldnt think that would be the problem unless you really push on the brake when putting it in R or P.
 
Well, at least when the bear gives me sarcasm, it comes with humor. Thanks Jim.

-Rob :)

<grin> let us know what you find when you pull off the brakes, eh? Never had that happen before.

Ive had it happen a couple times on my demolition derby cars, but you know how those are treated. They sit a lot in the weather. The rear wheels would lock up so I hit them with sledge hammers and other cars until I get annoyed enough to take the wheel off and pull all the shoes out. Leaving no rear brakes :)
 
LOL!

My Jetta does that from time to time....I just drag the wheel until it fixes itself....
 
Pulled all 4 wheels and checked the brakes. They look totally normal, and the drums came off easily. I'm a happy camper.

Did you set the park brake while the rig was in the garage???
There would be no real explanation of the brakes sticking if this was not the case as the shoes would be in the off position.

The parking brake cables are down in all the salt spray and that nasty stuff does get inside the cables and will corrode them in short order.

I would check the cables to see if they are working free and if not replace them.

I also make it a practice to never set the park brake in cold weather.

Or do it all the time keeps em from freezing i think. If i never used it all winter mine would get stuck come May I would think. I use mine almost everyday and so far so good.

My rigs too heavy for the tranny CLUNK outta park. Need the P/B
 
I've seen way too many frozen parking brakes in the winter to take a chance. Vehicle driving around generating heat, roads are snow/slush/wet. Driver sets parking brake. All that wetness freezes solid. Driver now beating on the drums with a BFH.

I never have had a problem with the parking brake sticking in the spring/summertime. Fall and winter I never use it, unless I know for sure the temps will stay above freezing.
 
I've seen this a few times. 1st when someone has sprayed "hot"(warm) brakes off with cold water. (mostly this happens at the firehouse after a call in the winter time)
2nd On big trucks with air brakes. Shoes are alot bigger and there is a lot more surface area to deal with mostly stick when truck has sat for awhile. Glad you came out ok on this Turbo I have seen u joints break when some tries to horse them loose a little too much.

Thanks for the information. Yes, I am also glad it came out OK, as I was starting to get concerned, especially as I realized I was leaving tire tracks (from 'pushing' the rear tires across the driveway) all over the place, and working both engine and tranny components pretty hard. I will say that things got a lot easier when I switched to 4WD-L, but still, it was a little scary when it gave a LOUD "POP" and things returned to normal.

Sure makes sense to me. I just happen to need mine. Funny thing is, evertyone else I know with older trucks are scared to use their ebrakes because

1. They are either already frozen and they say they never use it anyway

2. gets stuck on because they never use it and I put it on by accedent because I always use mine.

By freezing I meant rusted in, NFG. I guess it can defanately physically freeze. I do not ever use it overnight. That is for shit sure :)
