Just wanted to post a thanks. I drained out about 1/4" of fluid from both sides of the reservoir and adjusted the booster push rod 2 full turns back. That seemed to have helped. Did about 2 hours of driving on the same route as the other day and pedal is good. Responsive and some play before it engages the brakes. I stopped hard a few times, and simulated some traffic stop and go. Seems like it's doing as it should. I'll keep an eye on it as the days and miles pile up.
Here's what I suspect happened. Since I did the single to dual conversion, I've been fighting a leaking left front line at the block. To keep on top of it, I've been topping up the reservoir as I've been working the issue. I finally fixed it with some small copper flare crush gaskets I found on line. Stainless Steel lines look great, but what a PIA they can be to get sealed. So leak is fixed. But what I didn't realise is the leak was allowing the fluid to relieve pressure, like a relief valve. Once I fixed the leak, I didn't drain the reservoir giving the hot fluid no place to go but expanded everything ...like a freakin pressure cooker.
Needless to say...once again.. I learned about this old gal the hard way. There is no pressure relief valve in the system...I had no idea this was a totally sealed system. Well.. now I know
Thanks again for the help and great suggestions by you all.
