Ford Mercury Villager 1997 Owner's Manual page 221

NOTE: If a fault occurs in the anti-lock system, and the brake
warning light is not lit, the anti-lock system is disabled
but normal brake function remains operational.
Ford Motor Company has not found any negative effects of
mobile radio transmitting equipment installed on vehicles with
the ABS providing that the radio is installed according to the radio
manufacturer's instructions. However, if you have had a
mobile radio transmitter installed and the check ABS light comes
on (at any time other than immediately after turning the key
to the ON position) have your mobile radio dealer inspect the
installation. Also, if the ABS system is activated other than during
maximum braking, have your mobile radio installation
checked.
If Brakes Do Not Grip Well or Pedal is ''Low''
If the brake pedal seems "low" it may indicate the need for a
brake system inspection and/or service. Apply your parking brake
several times. If the condition has not improved, you should
have your brakes checked as soon as possible.
Occasional brake squeal during light to moderate stops does not
affect the function of the brake system and is normal.
However, if the squeal becomes very loud or if it becomes more
frequent, return the vehicle to your dealer for inspection.
Modifications to the suspension spring rates and/or
vehicle ride height may adversely affect vehicle stopping
ability.
