My main problem was indeed mounting on the lower brake pedal hole.
Having tried so many things and read so many posts. I kind of lost track. Sometimes things stare you in the face and you don't see them.
My brake pedal switch was adjusted all the way out which made it difficult to mount on the upper hole. But once I adjusted the switch all the way out, I was able to mount it on the upper hole just fine.
Now I get full pedal travel and a steady stream of fluid out both the primary and secondaries (with M/S mounted and lines running from the output back to the reservoir). Still got to bled the rear brakes but should be be able to now that I can actually push fluid out the master cylinder.
So to recap:
- Read the instructions again
- Hydroboost mounted to upper hole on brake pedal
- Adjust brake pedal light switch all the way out until you get things mounted then adjust as needed.
Thanks for all the replies and help!
