I don't know if this is your problem but some years ago I tried some cheap front pads from NAPA (when I say cheap I mean in the 50 - 75 dollar range). I had to brake hard on the interstate from 80 mph. Back on the road (I got run off) the steering was shaking like crazy. As I drove on, it slowly went away - pad deposits. If I had kept using the brakes hard this would have kept reoccurring.

 

I'm also running a cheep set of pads another week or so and ill have the money to order some hawk hp plus's when they come in I'm going to turn my rotors if they need it and see where it gose from their

 

Don't turn your rotors, just Rebed the pads.

 

^^this^^ rotate your tires and set the pressures like it says on the door jam. 32F 29R

 

Just rebed my pads brakes don't puls any more!!!! But the wheel still shakes at 80ish but then at a 100 goes away

 

Those same Hawk pads cured my brake pulse problem too. We worth the money.
Didn't have to resurface the rotors either.

Go get another balance and get you slightly bent rim straightened.
