I have a 1988 Ford F350 Diesel. I was driving it this morning and lost the brakes. I checked master cylinder for fluid it was full. I checked for noticable leaks seen none. Any suggestions?
Take it to a mechanic & tell him you need brakes looked at. They can run tests other than what your eyes can tell you.
oh....i have never seen this case.may be you have to contact service center.
