no, its definately a rattle.
and its not warped rotor thru the pedal, that is a different feel..
my bro was a gm tech for years so im trained to know the difference
(and it has a wee bit of that too :P)
heres the part that is bugging me, i took the car in and had an oil change done with an inspection by the tech i trust at a GM dealership.
i would think that he would have told me if there were other parts that were loose, worn or bad. he told me it was the left side bushing and link.
i had the actual work done by a local garage, that is more convient and i have used before, right now im waiting for a copy of the invoice because there is a discrepency. they said take care of that and you should be good to go.
i didnt notice hte rattle before because of the clunk, since i got the car back ive noticed it.
it is under normal braking when i notice it more and its just a rattle like the passenger seat rattles when its not back all the way..
