I recently left my 2001 Caravan parked with the parking brake on for a few months in my driveway. When I went to sell it (we got a newer Caravan!), the first test-driver noted that the parking brake was stuck and he drove it forward and backward in the driveway numerous times. The wheel turned, but you could hear a noticeable rubbing sound and there was some drag as if the parking brake was still slightly on, though it had supposedly been released.

A couple of months after that, I tried to pull forward and back again to test it, and the wheel just slid without turning! I got under the van and pulled on all of the cables to make sure they were free. Everything seemed mobile as far as cabling. So, I beat a bit on certain parts of the wheel to try and unseat anything stuck. I finally got the wheel to turn. After driving back and forth for quite there was just about perfect mobility, although I could still notice a tiny bit of rubbing. It was free enough to roll backwards in neutral down my 40-degree driveway, whereas before I had to put it in reverse and give it gas to do so.

I moved the van to a better location for visibility to sell it, but now I've noticed that the wheel is again completely locked. :/

What should I do? I was considering removing the parking brake cabling to that wheel completely. Or, is this a different issue now? I'm not averse to doing work on this issue myself, I'm just ignorant of how to proceed. So, any tips would be greatly appreciated!!

 

Probably some large rust build up in there. Probably need to remove the rotor or drum and clean it up in there.

 

Can I accomplish those things with basic tools? I'm a newbie to this, so I may need to buy some tools. How to clean the rust off? Is there a chemical that works well for this, or just scrape it off?

Thanks!!

 

SUBJECT:
Snow/Water Ingestion Into Rear Brake Drum
OVERVIEW:
This bulletin involves installing a revised rear drum brake support (backing) plate and
possible replacement of the rear brake shoes and drums.
MODELS:
2001 - 2006 (RS) Town & Country/Voyager/Caravan
1996 - 2000 (NS) Town & Country/Caravan/Voyager
1996 - 2000 (GS) Chrysler Voyager (International Markets)
NOTE: This bulletin applies to vehicles equipped with sales codes BRA, BRB, or
BRV (front disc/rear drum brakes) built on or before March 7, 2006 (MDH
0307XX).
SYMPTOM/CONDITION:
While driving through deep or blowing snow/water, the snow/water may enter the rear
brake drums causing rust to develop on the rear brake drum and shoe friction surfaces.
This condition can lead to temporary freezing of the rear brake linings to the drums. This
symptom is experienced after the vehicle has been parked in below freezing temperatures
long enough for the snow/water to freeze inside of the rear brake drums. When the parking
brake has been applied the symptom is more likely to occur.
DIAGNOSIS:
If the vehicle operator describes the Symptom/Condition above, perform the Repair

REPAIR PROCEDURE:
1. Raise the vehicle on a suitable hoist.
2. Remove both rear wheel and tire assemblies.
3. Remove both brake drums. It may be necessary to adjust the rear shoes to aid in
removing the drum.
4. Create slack in the rear park brake cables. With the park brake pedal in the released
position pull down and rearward on the core of the front park brake cable then install a
pair of locking pliers on the core of the front park brake cable just rearward of the rear
body outrigger bracket (Fig. 1).

CAUTION: WHEN WORKING IN THE AREA OF THE REAR HUB/BEARING
ASSEMBLY AND WHEN REMOVING IT FROM THE REAR AXLE, CARE
MUST BE USED SO THE TEETH OF THE TONE WHEEL ARE NOT
DAMAGED. DAMAGE TO THE TONE WHEEL TEETH WILL RESULT IN
FALSE ABS CYCLING AND CORROSION OF THE TONE WHEEL.

If Special Tool 8214-2 will not fit into the hole in the end casting, file or grind the
flashing from the hole until the tool fits properly. Special Tool 8214-2 must be
against and supported by the axle plate when pressing the bearing out of the axle.
c. Align bolt in Special Tool 8214-2 with the pilot hole in Special Tool 8214-1. Tighten
the bolt against Special Tool 8214-1.

Wow, thanks for all the detailed info. I guess I'm pulling the wheel and sanding off some rust this weekend!
