1996 Ford Bronco Owner's Manual - Page 206

NOTE: It is important to note that when the ABS Warning Light is illuminated the ABS system is disabled. The vehicle must be serviced immediately to restore the benefits of the Anti-lock system. NOTE: Mobile phones or radio transmitters not installed by Ford Motor Company may interfere with the Anti-lock System. Should the Anti-lock system activate unexpectedly or the Anti-lock Warning Light illuminate after installation of such a unit, have the installation of the unit checked. If Brakes Do Not Grip Well or Pedal is "Low" If brakes do not grip well, it may indicate the rear drum brakes need adjustment. To do this, drive the vehicle in reverse at 5 mph (8 km/h) on level, dry pavement. Stop the vehicle by firmly applying the brakes. Repeat this procedure four or five times. If during normal operation the brake pedal seems "low", it may indicate the need for a brake system inspection and/or service. 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 annoyingly loud or increases significantly in frequency of occurrence, return the vehicle to your dealer for inspection. 206
