Modern antilock brakes are far more reliable and less likely to need repair than the older systems. Most common is dirt getting into the sensors, which activates the ABS light and shuts down the system. When this happened on our 100,000 mile Neon we examined and tried to clean each sensor. We ended up having the system checked with a code-checker to find out which sensor was not working, and took it out and cleaned it - which worked once we reset the computer (by the unplug-the-battery method).
