Brake bleed question real time help needed (2 Viewers)

[ColoradoCarlisle]

Had to replace one caliper and now Im bleeding. When the truck is off I can get what feels like good pressure but when I start the truck the booster kicks in and it feels spoongy. Do you bleed with the truck off or on. I think I still have more air in there for sure but just wondering if you bleed with it started or off.

When I bled my whole system I did it with the engine off.

Which caliper did you replace, front or rear?

I have never had good luck bleeding the 80 with the truck off. Not sure why, and all the other Cruisers bleed fine with the truck off, but on the 80, I bleed with the motor running. Try it and see what happens.
