problem with brakes

i changed out my rotors to the cross-drilled ones and also got my pads changed to those ones that reduce brake dust and now when i brake there's some weird noises, seems loud, grinding and also my steering wheel moves a little if i brake hard..... could it be the rotors????? i only put 400-500 miles since i changed them.....
You Will hear Air passing through the Drilled rotors..I Hear
It on mine. More so from the rears...
It Sounds Like You warped the brake rotors.
Did You break the Pads/rotors in....NO Hard stops for 100 miles?
The Steering Wheel Vibration is a Sign of warped rotors when the Brakes are applied....You Can Surface drilled rotors on a Mill
But Your dad has a shop....Im Sure He will fix the problem
