it only does it when i brake. i do need to get the car aligned really bad, but wanted to know what else could cause it. it has new rotors on it also.

 

loose rotors
loose lugs
uneven wear on pads
untrue rotors

many things

 

if they werent heat treated/not broken in for roughly 500 miles with no heavy breaking rotors can be warped....

 

my money is on bad rotors... jack the car up and check if you hear a light scraping noise when the wheel turns. if the scrape noise occurs only for an instant, like when a certain point of the rotor passes through the pad area, then you know somethings not lining up right. i would have a shop take a look at that or maybe a seacond set of hands

 

dumbass

 

who?

 

it can sometimes be a matter or tire pressure. i went through a front end shake and got all worried, come to find out i had really uneven tire pressure. fixed it right away

oh i thought u were talking to me... but yea if the got low profile tires/rims tire pressure can be a factor
