The front brakes were compressed during a brake job to turn the rotors, the rear got compressed to turn the rotors and get new pads. No caliper hoses got pinched or abs wires got pinched. When I drive the vehicle with a scan tool I have correct speed to each of my wheel speed sensors. I tried bleeding the brakes, bleeding the abs and tapping the brake fluid reservoir to unstick the float. Problem still persists.

What codes are pushing the warning lights and messages?
You need a scanner that can read them; they're not standard OBD codes that the inexpensive code readers only read. If there's a light or a message, there's a code.
Are you using generic OBD or the manufacturer's code selection? Generic OBD won't read them. And read them while the messages are on the DIC.
Checked more than engine codes, like chassis or body codes? If the message is on the DIC, there's a code.
