ABS light on and Brake light on after brake job on 21' F150 V8 4x4. Bled the brakes properly (twice.) Tried using scan tools to get rid of but nothing. Will also turn on Advance Trac and Pre Collision warnings as well.Anyone have any fixes to it? Could there still be air inside the abs system?Everything was perfectly fine before the brakes change other than the pads of course.

 

Do you have Electronic Parking Brake and did you put it in Maintenance Mode before tearing apart the rears. I don’t have a answer to fix it, just know it could be the cause of your problems.

 

Yes and Yes.

 

Sounds like one or more of your wheel sensors is either broken or disconnected. None of those functions can operate properly without a signal from all 4 wheels.
