Need help with steering shakes

E39 528 1998 with 120K miles on drived by my wife and she complained about steering shakes between 70-80 and when slightly push brakes.
just try it myself and CONFIRM IT! and need little bit help!
What was done for last 6 months
all 4 wheel bearins[ ***]
front -both lower control and thrust arms
same with rear
all 4 rotors with new brake shoes
new DWS tires[ already put 7K miles on ] still in great shape
checked all 4 rims [ 17 size]
good alignment
good balance
checked by hands tie rods for steering-No play
What else can it be? and how check if calipers is stuck? already touch it with hands and feels like same temperature

Are you sure it was properly aligned? - Weighted

It's a looooong story. The short of it is that the way your wife brakes is what is likely causing the rotors to have uneven pad deposition, if it's what I think it is.

Of course, there are a zillion reasons for vibration - so I'm just talking about the most common (which fits your description.

The short term solution is free. So is the long term solution.
