1995 Chevrolet S10 Question: ABS brake system failure
The ABS system consists of a computer that receives inputs from each wheel as to how fast each individual wheel is turning, if a wheel "locks up" the computer controls solenoids that controls fluid pressure applied to each wheel to slow it down without allowing the wheel to lock up. These solenoids open and close rapidly, the component it sounds like you are describing is the assembly that holds these solenoids and has all the brake lines attached to it. - patrick mannion
The Anti-lock brake system (ABS) control unit may fail internally causing the ABS warning light to illuminate.
