New rotors and pads should take care of it. Torque the lug nuts to 100ftlbs.

It's possible it's just overnight rust that has to be wiped of the first time you use them. I'm just guessing? Either that or you've got something under a rotor on the mounting surface. That usually is constant, though.

The abs light is on occasionally but not constant

It is not a daily event, it is happening every time the vehicle is started and driven

Do you feel it in the pedal, or does the whole vehicle shake?

There is also a proper break-in procedure for new rotors and pads.

Does it do it right after you start the engine without even moving? If so, it's just the ABS doing its self check.
