I have a guy that has one that I think I can rent. I had him do the process before but he rushed through it and I don't think it was properly done. I was inside the car pushing the brake pedal when he needed and I could hear/feel the ABS pump cycling.

If the ABS followed by a caliper bleed does not fix the issue I will have to do a Master Cylinder bench bleed, followed by another ABS bleed and then a caliper bleed to get all air out.

Is there a way to access the GM service manual? Just curious to the recommended bench bleed process.
