My ABS, brake stays on and the tire pressure light blinks

Instructions

1

Park the vehicle and turn the engine off.
2

Turn the ignition switch to the "ON/RUN" position.
3

Press and hold the tire pressure warning reset switch until the TPMS light flashes on and off three times. The reset switch is located on the bottom of the steering column on most Pontiac vehicles.
4

Leave the ignition switch on for three to five minutes to give the computer a chance to reset and calibrate the system. Turn the ignition switch off.

You must have done something to ABS sensor on that wheel when you changed hub. Recheck your work.

Yep this happens when one of the tire pressure sensors goes out, you will need to do a CAN scan to see which one it is.

This video will show you how:
