With mechanical faults ruled out this could be a wheel trueness or overall balance problem. Note that the heavier rotor and drums used for HD applications are also part of the balance of the wheel as an assembly.
On vehicle high speed balance may be available if plain wheel and tire balance is showing good.
I might be off on the wrong track for this specific issue but have been thru this with the brake parts being a balance problem. So far I haven't found a place or practical way to rebalance used brake drums and rotors and rely on quality new ones to have done that properly.
Of interest: It's been my own experience that this balance and trueness is noticed most at the speeds you mentioned. Have had some return to smooth above a certain speed like you have noticed!
