1999 Chevy Lumina 3.1 ABS not engaging
 

Hello,


I just bought this work car about 2 months ago, and have dumped a lot of money into the braking system as follows.


1: 2 rear brake lines replaced do to severe rust caused them to blowout.
2: Passenger front brake caliper replaced do to lockup
3: Front Rotors replaced.
4: Rear drum brakes rebuilt.
(The braking system was bleed after all this, but I don't feel I got all the air out as they are kinda spongy after several attempts, but enough pedal so I gave up on that.


Ok now for the issue I had to slam on the brakes in the snow as someone cut me off and I didn't feel the ABS engage and I could tell it was full lockup. I haven't gotten any warning lights what so ever so I have no clue what could be causing this issue.. I'm really concerned about this issue as my wife uses this car for work and snow has fallen upon us so no abs is just to unsafe for her to drive this way.
