Default problems with oem drilled/slotted rotors

Recently they are starting to grind and make a grinding feel when im lightly on the brakes. (right front) If I stop hard they dont. Is this normal? Also I slammed them at about 60 and only my left front squeeled before abs kicked on. Does that mean the right front isnt closing properly?
thanks
TJ

Just resurface the rotor and you will be fine

Were the holes drilled after the rotor was cast or was it cast with the holes?

Any cracks (even hairline) in the rotors? Have you checked what your pads look like? Sometimes drilling/slotting and eat away at your pads in an abnormal fashion.

What are OEM drilled and slotted rotors? You made them yourself?

please don't use rotors that you've drilled your own holes in (with [very] few exceptions.)

Can you brake hard in a straight line with little (or no) effort?
What pads?
Used pads on new rotors?
All the shimms are there?
