Bill,
Had something like that happen to me.
Did a complete front brake job on my old D 50 truck.
I did everything by the book. The works. The discs were
well within their specs, and I had them resurfaced at a
professional brake shop. Problem: The brakes were
pulsating worse after the discs were turned than before
I redid them.
Took me a while to figure out the cause.
Turned out the guy working in the brake shop didn't mount
the discs right when he resurfaced them. Only found out
after I paid another shop to resurface the discs again.
Luckily there was lots of metal left on them.
Anyway, after that the brakes were smooth as silk.
I tell you it was a real bummer.
Of course, in your case, it could be something else.
Just a thought.
