Hi Ron you are describing a failed frt wheel speed sensors' symptoms exactly. It makes the abs unit think that the wheel has stopped turning. Thus engaging the anti-lock.
The home test is to check for continuity with a DVOM. Unplug the sensor at the wheel well, connect your DVOM to the sensor. Set your meter to a continuity test and then twist, and pull on the lead to the wheel sensor.
You will find an intermittent open in one or both frt sensors. Remove and replace the offending bit(s).
