my shimmy is felt in the brake pedal. I have 100k, replaced brake pads at 60K without turning the rotors down-(DUMB)-because the pads and rotors did not wear well they are groved and one rotor is the back looks like it has rust spots where the pad never makes contact, or that calaper is not working correctly?? I am going to replace the rear rotors and new pads tomorrow, could a warped rotor in the rear give a shimmy on the pedel?? To ansewer your question it is pretty constant with speed, obviousley less pronounced at slower speed, but still there
THANKS!
