The pumping and releasing of brakes by the unit is brake pressure modulation
The ABS system on a 2001 Chevy is to monitor the brake pedal pressure.
The ABS and brake warning lights will come on in a vehicle when an error is detecting in the he system. This can range from low fluid or pressure to sensor and component failure.
Your car could be losing brake pressure because you have a bad ABS control module. It also could be a bad brake booster.
Low brake bressure can be caused by a worn accumulator, poor pump performance, a bypassing brake booster or an inaccurate pressure sensor. To test your brake accumulator, turn the key to the on position and pump the brake pedal. A properly functioning accumulator will give you 25-30 brake applications before the low brake pressure light illuminates
it sounds like you may have a problem with your abs system ,on the newer s10s the abs system applies most of the brake pressure for you,i would start there it sounds like you may have a problem with your abs system ,on the newer s10s the abs system applies most of the brake pressure for you,i would start there
ABS system is inoperable and there is something wrong with the non-ABS part of your brake system.
An ABS brake is another term for an antilock brake, a brake fitted to some vehicles to prevent skidding and compensate for overbraking.
ABS systems, in general, have to be bled with a power unit. This forces brake fluid under hydraulic pressure through the brake system and eliminates any air in the system. ABS units cannot be bled satisfactorily without it. Any auto repair shop that does brakes will have the capability to do this.
In most cases, the brakes will function fine even if the ABS is not working (you just won't have the ABS feature). If you have to exert more pressure than normal on the brakes, you can be looking at an issue with the brake booster or some other part not necessarily associated with the ABS system. It sounds like the ABS light might be a secondary symptom of a larger problem. I would recommend taking the vehicle to a qualified shop asap.
A drop in brake fluid pressure (caused by, say a leak or crack)
turn off car and pump the brake pedal until pressure is relieved
