Complete lock up of brakes while in operation. Third random incident in 2 months, once pulling a horse trailer. No answers at the dealership other than bring it back when its doing it. That might work if it locks up on the interstate again and I can control the death skid into the dealership parking lot.

Driving 65 MPH and the brakes lock up. They release and go 200 ft and lock up again.

There was no one behind me, this could have been bad.

Pulled over shut the truck off. Checked the emergency brake. Started it and got off the highway.

Scary situation going that fast.

Update from Jun 20, 2018: Well I know longer sieve it was the brakes. The truck down shifted and the ford dealer said nothing wrong. This is going to cost someone there life one day.

Driving about 45 mph and brakes lock up and, so I pull over and shut the truck off. Wait about a minute and turn truck on and everything is fine. This happened about three times in the last year.
