Vibration when hitting the brakes at speeds above 30mph

I'm trying to figure out what I need to check or replace on my 2002 grand prix 98000 miles...... Seems to be a vibration when hitting the brakes even slightly or mashing on them. I'm thinking rotors? or maybe just a simple balance?

could be the ball joints as well they are easy to check, or have checked. unless your brakes are old and u beat the daylights out of them, then i would think warped rotors.
 


Thanks for the help guys.... just purchased the car about a week ago it was either going to be a hub or rotors..... ordered some rear rotors since i can hear it a little more in the rear end. Lets try the cheap route first. I'll let you know what I find
 
I had vibration during braking after I replaced my sway bars, lateral arms, and trailing arms. Turns out I needed to tighten one of the rear trailing arm bolts at the front end.
 
.. Def the left rear rotor missing half of the surface!! Tried to upload a picture but says file size is to big when its only 25KB. Thanks for the help guys!

I eventually gave up and got a photobucket.... makes it much easier now, despite never wanting to get one. Then you just link the pics over.
 
AC delco 80 bucks for pads and rotors.... not to bad I plan on puttin some pics up here in a day or two just been a little busy!
 
re-bed your pads?

warping rotors is ACTUALLY difficult.

having the adhesive layer the pad lays down on the rotor come off is easy if you bought cheap pads :)
 


vibration on the steering wheel while braking almost always front rotors, vibration on the pedals while braking almost always rear rotors!
