I have a 93 Taurus and it has developed a hard brake pedal. It seems to work fine when you first press the breaks but then the pedal gets real hard to push. If you let off and push again, it work good for second or two. It is almost like the power booster does not hold a vacuum. Is this an ABS problem? I am not even sure I have ABS system. Any help would be appreciated.
