Abs pump!!! did you pump the breaks when you were bleeding them? as a rule with abs you just apply the brake and D pump will supply enough pressure to bleed they recommend you do not pump!! them standard brakes yes you must pump to bleed.

If there is an ABS issue it will turn on the red brake light as well. Were these lights on before the repair? You can try disconnecting the battery to see if the ABS resets. If the lights come back on you will have to have a scan test performed on the ABS system to isolate the problem
The brake and ABS lights could be on because of a brake or ABS problem. The ABS system uses the hydraulic brake system in addition to the ABS components. The high idle could be a vac leak or a problem with the idle air control valve. You could check the computer for trouble codes even if the warning light does not stay on.
HAVE CAR ABS BRAKES CODE SCAN.BECAUSE WHEN ABS LIGHT IS ON.YOUR CAR ABS BRAKES NOT WORKING.CHECK ABS BRAKES FUSE AND RELAYS.IF ALL IS GOOD.HAVE DEALERSHIP OR GARAGE CHECK ABS BRAKE SYSTEM BECAUSE ABS BRAKE UNIT IS PART OF THE BRAKE MASTER CYLINDER IF KEEP DRIVING COULD END UP WITH BRAKE FAILURE.CAR NOT SAFE TO DRIVE WHEN ABS OR ANY WARNING BRAKE LIGHT APPEARS.
computer does that, or you have to have enough brake fluid preasure also, check for leaking lines (brake lines). make sure fluid is full.abs system has dump valves , if there was a problem abs light would be on. but abs might lite if not enough preasure hope this helps.
You had it scanned? They didn't find any codes? If there were no codes, did the ABS computer even communicate? Also did you check the brake fluid, most newer cars have a float switch in the master. If the fluid is low that will set off the lights.
Chevys are bare to blead, especially if it has ABS. Chevy dealers actually use TECH 2 / their computer to blead ABS systems properly. With it, they open the ports in ABS module, which helps the brake fluid flow. Unless of course you have ripped the sensor wire for ABS by accident.
