“Takata recall: while I was driving 70 MPH on the freeway, the car suddenly started shaking and in the matter of few seconds the car immediately stopped in the middle of the freeway. I tried to move over to the side of the freeway slowly, to a safe place, was difficult, because after I moved the car to the side of the road, I looked at the wheels and it started making a metal against metal noise, like brakes on a train. After I called the towing, they took me to the dealer, in carson city, nevada. After two days the dealer called me back and told me I was driving on a turned on emergency brake. …”

From the drivers perspective it appears normal other than having less or no tension when the parking brake lever is applied.or released. …”

My mechanic has told that with these models and ford transit that expect to change brakes every 15000 miles.
