^ok i got it. you are right then - if the brake pedal starts sinking to the floor without engaging the actual braking then that is a problem - the Ford techs should be knowledgeable enough to know that.

did they at least acknowledge that the sinking of the brake pedal was occurring, and claim that it was "normal"? or could they not replicate the problem? not only are you getting screwed out of your money, if somebody gets hurt or killed because the brakes failed on a unit the Ford dealers insist was ok, then you have a nice multimillion dollar lawsuit on your hands...
