Brake Disc Caliper problems of the 2014 Dodge Grand Caravan

10/19/2019, vehicle stationary: the driver's side rear caliper froze in the full-on position when lightly using the emergency brake. I was just a � mile from home and drove it to my garage (less that 30 mph). It was dangerously hot and would have caused a fire and major breakdown had I been on my 18-hour freeway commute. I jacked up the rear, removed the tire and saw that the e-brake spring had not returned the caliper to the brake off position. I was able to return it by lightly tapping the e-brake lever to the off position. At that point the brake caliper mostly worked as it should. However, re-applying the e-brake would again refreeze the brake to full on. I replaced with a mopar oem caliper and all is well again. I suspect the e-brake mechanism within the caliper failed. All my mileage is extended freeway commuting between two different state residences. The front brake pads have never been replaced and still measured 5/16� thick. The original rear pads had at least half their life span and I did not replace those either. Needless to say, I fear using the e-brake with this vehicle. The caliper on the driver's side rear cannot take the limited e-brake use without failing.

While driving over 40 mph, suddenly brakes get spastic, they are trying to brake as I am driving on expressway. This problem wore out completely the brakes and calipers at 18000 miles. Got new brakes (Dodge regulation) and now same thing happened on expressway while driving over 45mph. I need to drive on x-ways.
