can the brake pads cause the steering wheel to shimmy. i have just replaced the front rotors with slotted rotors and i still have the shimmy can the brake pads cause this(they are the stock pads with 20,000 miles)
If so i will be replacing them with some hawk pads

Yea if their worn very unevenly

yes it can

Does the steering wheel vibrate when you apply brake at speeds over 30mph?

I have hawk hp+ pads and they cause the steering wheel to shimmy . There is nothing you can do about beside buy different brakes, dont try to file the edges down like many threads suggest , they will crack and fall apart. Bottom Line i will NEVER buy hawk again . Other members experience no problems with these brakes but i have had nothing but trouble with them

i think warped rotors will cause the "harlem shake"

Yes is only does it over 30 or 40 mph

MIne does that when I initially apply the brakes at over ~50mph but then quickly goes away. Im on stock pads and rotors.
