Rear brake drum rust on Dodge Grand Caravan

While driving through deep or blowing snow/water, moisture may enter the rear brake drums, causing rust to develop on the rear brake drum and shoe friction surfaces. Over time, repeated (and sometimes infrequent) exposure to the snow can lead to temporary freezing of the rear brake linings to the drums. A revised brake drum and brake drum backing plate is available.

1999 Dodge Grand Caravan 105,000 mi,
If we don't use the van frequently (at least once a week-whereas sometimes it can be a couple weeks or more between uses) and we keep the parking brake on (to keep the pressure off the transmission-which doesn't shift past 2nd gear-routinely), the rear brakes lockup solid and I end up having to spend 5 or 10 minutes gunning the engine and frequently shifting back and forth between Forward and Reverse until the vehicle starts moving and the tires stop squealing (from scrapping the ground without turning)and start rolling properly. But today, the back and forth process actually ended up blowing out the right, rear passenger brake line or the brake drum seal(s) and spewed brake fluid all over the tires and up and down our driveway. We lost all braking ability and the brake pedal now sinks to the floor. This is very dangerous if this seal would've blown while on the road driving.
2005 Dodge Grand Caravan 180,000 mi,
Same common issue; I just bought the vehicle and replaced the front brakes. Back brakes locked on passenger side out of the blue. Didn't know this was common... Will now carry hammer with me. ;)
1996 Dodge Grand Caravan 140,000 mi,
Back brakes are tight when not used often but loosen up as I drive a mile and do not get hot.
