My 99 Contour (ATX, 85k) has an ABS problem, the ABS system is causing a very minor pulsing of the brake pedal even on dry pavement when I know the tires are not slipping.
I am familiar with what warped rotors feel like and I know what the ABS feels like when fully engaged and this feeling I have in the pedal is as if the ABS system is pulsing but only just barley, it happens every time I hit the brakes and is always the same frequency of pulsing whether going very slow or at highway speeds (warped rotors would change pulsing frequency with speed).
A search did not reveal anyone else having a similar issue in this forum.
Any help would be greatly appreciated.

Thank you,

Jerrit
