tlkfmca Report post Posted July 28, 2019 I just had a problem with the brakes locking up on my 2018 Ford C Max when it was last towed. Im being told that the problem is with the vacuum pump on the vehicle inadvertently engaging which then applies the brakes. Has any body else experience this problem?
