Is the problem at really slow speeds when you come to a stop? this usually a sign that a tone ring or wheel speed sensor is going bad you will have to take it to a local repair shop and have them scan your abs to find out what wheel is causing the problems.

Front left brake keeps locking up


i suspect that you have a bad caliper which is sticking. look there first, and always replace both if on the front, since murphy's law usually applies. thats where 60% of your stopping power comes from. the anti lock system won't normally cause the problem you describe, but a bad caliper will. make sure the rotors are ok as well.

What does the anti lock light on the dash mean?


The anti-lock light is indicating that your anti-lock brake system has a problem. Check fluid level. Could be a sensor, time for brake service etc, but I wouldn't wait too long to have it checked, just in case something serious. Anti-lock brake problems may cause a wheel or more, or all, to lock up in a panic stop situation. When was last service on brakes done?

Problem with my cruise control and ABS light on 03 Explorer


Anti-Lock Control —Vehicles Built After 03/2002 The 3-channel anti-lock brake system consists of the following components:
  • front wheel speed sensors
  • front wheel speed sensor rings
  • hydraulic control unit (HCU)
  • Anti-lock brake control module (ECU)
  • rear wheel speed sensor
  • rear wheel speed sensor rings
  • yellow anti-lock brake warning indicator
The 4-channel anti-lock brake system with traction control and stability assist system consists of the following components:
  • active brake booster with integral solenoid
  • brake booster release switch
  • front wheel speed sensors
  • front wheel speed sensor rings
  • hydraulic control unit (HCU)
  • stability assist module (ECU)
  • stability assist event indicator
  • lateral accelerometer
  • longitudinal accelerometer (4x4)
  • rear wheel speed sensors
  • rear wheel speed sensor rings
  • steering wheel position sensor
  • yaw rate sensor
  • yellow anti-lock brake warning indicator
  • brake pressure transducer
  • traction control switch
---------------------------------------------------------------------
I suspect the abs issue is causing the speed control not to work if it happened at the same time the cruise control stopped working. When the yellow ABS light comes on, it means the ABS is dactivated. You may have a faulty accelerometer which senses acceleration and yaw (side to side lean). I have not seen a bad one but you said it is sensitive to acceleration.
I would unplug it and see what happens. The connector should have a small tab to depress so you can pull the connector out.
Here is where it is:

Accelerometer Removal and Installation
  1. NOTE: The accelerometer is located under the center, rear passenger seat carpet. (I think you have to remove seat for access).
    Cut the carpeting along the perforations.
  1. Disconnect the electrical connector.
  1. Remove the nuts and remove the accelerometer.

Have dealer hook up tester and pull fault codes if you can't find an easy solution.
Some background info
  • A malfunction in the anti-lock brake system will cause the anti-lock brake control module to shut off or inhibit the system. However, normal power-assisted braking remains.
  • Malfunctions are indicated by the yellow ABS warning indicator in the instrument cluster.
  • The anti-lock brake system is self-monitoring. When the ignition switch is turned to the RUN position, the anti-lock brake control module will carry out a preliminary self-check on the anti-lock electrical system indicated by a three-second illumination of the yellow ABS warning indicator in the instrument cluster.
  • During vehicle operation, including normal and anti-lock braking, the anti-lock brake control module monitors all electrical anti-lock functions and some hydraulic operations.
  • Each time the vehicle is driven, as soon as vehicle speed reaches approximately 20 km/h (12mph), the anti-lock brake control module turns on the pump motor for approximately one-half second. At this time, a mechanical noise may be heard. This is a normal function of the self-check by the anti-lock brake control module.
  • Pedal pulsation coupled with noise while braking on loose gravel, bumps, wet or snowy roads is normal and indicates correct functioning of the anti-lock brake system.
  • Warning Lamp Indicator
    The anti-lock brake system (ABS) uses the yellow ABS warning indicator to alert the driver of a malfunctions in the ABS.
    The yellow ABS warning indicator will come on to warn the driver that the ABS has been turned off due to a symptom that exists in the ABS. Normal power assist braking remains but wheels can lock during a panic stop while the yellow ABS warning indicator is illuminated.

    Please report back, I am curious if that is what it is. Good luck
