Question about 2000 Chevrolet Blazer
Hmm ok this is a tough one.. Its more than likely one of two things..
1.) the abs sensor.. this will account for the light being on and it will also account for the brake not working propperly.. to verify this,, Locate and remove the abs fuse.. Its in the fuse panel under the hood.,, under the cover is a diagram with the fuse layout.. remove the abs fuse and drive with the vehicle.. If your brake works perfectly then you need to change the abs sensor,,
2.) the second is the bran box / the ECU (control unit) ,, to verify this you will need to have a diagnostic machine (code reader) connect to the module and detect all the fault codes.. This is not likely but very possible.. Verify the sensor first and then check the control unit..
Now take into consideration that is the abs is not working propperly and you remove the fuse ,, YOUR BRAKE WILL WORK!!!! just the abs system wont,, you can drive your car safely without the abs,, it will just like driving a car with no abs or before they invented it.. what the abs does is hold and release quickly so you dont get an abrupt stop,, with the abs you will stop quicker so it will take a bit getting used to so you wont step on the pedal hard,,

Abs problems are hard to pin point with out troubleshooting the whole system. Be sure the fluid is full, check all wiring to the mod. and the sensors. If it did not want to stop make sure of and vacuum hoses to the booster. The module can be found in salvage yards now and will not cost to much if you shop around. Most problems I have seen have been the ECU being bad, you have to look at the epoxy sealing to the plastic, if you see a gap water gets in and shorts out the electronics.

this warning light or any other stays on in the dash it is indicating
that the systems control module (or the system sensor in the case of
lights like low oil pressure, door open indicators etc.) has detected
a fault, it then disables the system (this applies to ABS,TCS, TCM,
SRS, TPMS and BCM faults and others) as long as the light is on. You
must now have the dealer hook up a special electronic diagnostic tool
and "scan" the system for the fault code that is stored for
Legend of Abbreviations. ABS Anti-lock brake system. TCS Traction control system, TCM Transmission control module, SRS Supplemental restraint system, BCM Body control module. TPMS Tire Pressure Monitor System
