Well u have to check brake pad sensor or brsk fluid level first

When your abs light comes on it means that something is wrong with you ABS system. Sometimes the abs sensor get durty and can make the ABS light come on in the dash.

When the ABS light is on the ABS system is deactivated. Meaning, when the abs is light is on and you brake, the tires will lock up with heavy braking.

Escapes have a common issue of the ABS excitor rings cracking causing ABS problems. Sometimes it activates on almost every brake application. It may set a code in the ABS computer for an intermitten wheel speed sensor or no wheel speed signal. Check all the "rings" on the outside of all four axleshafts. If none of the rings are cracked it is likely a bad ABS wheel speed sensor.

This is all related to the vehicle speed sensor. This sensor sends information to the speedometer, abs, and wing computer. You need to get it replaced and it should fix all the problems.

Sounds like a dry caliper(if disc brakes) or dry wheel cylinder (if drum). Some times a good cleaning goes a long way but may take some disassembling to do it.

I had this problem.
When they test the ABS with the car not running the ABS was OK.
When the take the car for a drive still hook up to the tester, they find that one of the wheel sensor was bad.
I replaced it and every thing was OK.

sounds like an intermittant fault in the ABS control valve, most likely one of the solenoid valves is sticking or out of self test range..
