Thanks to all that have replied.

Rick, the answer to your question is yes, the pedal dropped by itself during the vacum bleeding proceedure. We have not been able to get it to return to its original position yet.
I contacted Tilton tech support and they said they did not know of any reason vacum bleeding could have caused this.
My friend an I will try again on Wednesday night using your suggestions.
Thanks again for your help, I really appreciate it,
Roger
