Dodge Grand Caravan
Report: Rear brake drum rust
Dodge Grand Caravan Problem
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.

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.
