So I finally got a new g60 caliper the bleeder screw and inlet are in
different places but that’s not my problem although I thought I installed
the caliper incorrectly for a second. I bled the system with the motive
bleeder. Looked like I got all the bubbles out let it drain for a while
after I stopped seeing bubbles but I have no pedal pressure when the van is
running. however I do have pedal pressure when it’s not. I thought I just
had to bleed it again maybe some air still trapped in the system but the
fact I have pedal pressure when it’s not running and none when it is is
making me think I have a different issue. Anyone have any idea? Is that
what that little sensor on the master cylinder does?
