95 Accord EXL 4cyl 4dr 187K

Recently, I put on a new master cylinder. And just last night, I replaced the front brake pads.

Everything seemed find. Then once I got going and the car got warmed up, the front end of the car, my brake pedal and my steering wheel vibrate violently when I apply the brakes.

I did not bleed the front calipers after putting in the pads; but my buddy seems to think it's warped rotors that I wouldn't necessarily see. And if they are warped, I would not necessarily would have noticed it with the old pads because they had conformed, etc.

When I took off the old pads, I did notice that all the pads were cracked.

The front rotors were turned not that long ago as well.

Anyone have any ideas of what the problem could be?
