Bad sensor, bad calibration or a bad compressor can all cause that issue. Or having the front/rear valve blocks mixed up. They are specific to front/rear even though they look the same.

 

Update part 3. Or 4.

seems after driving for a while i have developed a squeak somewhere right rear. What should I check for especially given components replaced?

slow speed most noticeable (like in the parking lot)

 

…check to make sure your spare tire is tight. Lol

lesson learned.
