Thread: 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?

sounds like warped rotors!!! If it was balance then it would probably shake while just driving!!!

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

Had ok luck with cheap ones from Advanced, maybe $40 bucks each.

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!

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!
