info Chevy P30 hydro boost brake/power sterring bleeding

I replaced both calipers on mine a couple of weeks ago and "gravity" bled them. I just open the bleeder valve on the one farthest from the MC. Wait until just fluid comes out with no air bubbles, and repeat on the other side. It works fine. If the pedal isn't returning to normal, I'd look into a possible problem with the master cylinder. If it was allowed to drain empty while replacing the line, it might need bench-bled.
