OK, I think I have it sorted out now.

First, Thanks to William for putting the kit together and for some help along the way.
Second, like all kits it ain't a simple bolt on.

For some reason when the piston push rod was cut to 3.5 inches as instructed it was too short . Or so it seemed. More than 1 mm play at the pedal and not a lot of threads left to adjust it.
Machined another put in new pads and it seemed fine until the brakes warmed up and suddenly I was stranded on the side of the road (just barely made it ) with seized brakes.
Screwed in the rod and was able to continue.
Not sure if the original at 3.5 would work after all but after bleeding the brakes 3 times I am happy to leave well enough alone.

One other note;
The plastic " Y " splitter - shattered when the hoses were being pushed in. Cheap plastic . Replaced with a brass one.

Also;
In my desperate attempts to eliminate all the air from the system I realized that there are 2 bleeder valves , one on each half of the rear calipers.
Never noticed that and didn't come across it in the owners manual or 100 projects.
I got air out of both halves and both sides and that seemed to solve it.
Are my rear calipers "special" ?
Is it overkill to bleed both sides [of the calipers] under normal conditions ?
