Do you have aftermarket longtube headers? If so My guess would be that when you go over the bumps the headers are banging off of your floorboard. I believe one of the sponsoprs on here like Thunder Racing or Tbyrne motorsports sells header hanger.

no it does not hit... im thinking it might be like something loose..
its like something not screwed on fully so wen i go up bumbs or brake fast it moves forward and backward...
im thinking it might he the brake pads cuz it sounds like its comming for the front tire and the back tire...
did i miss anything i just bought some atozone ones and compressed and putt them on and bled the brakes...they work great

o my cars all stock

there is no glue the "glue" he is refering to is called lube just the opposite haha. I doubt it is the pad. Did it just start right after you did the brakes?

No offense man, but you asked for help then you're shooting down everybody's input. If you know what it is cool, glad you figured it out! If you don't, at least take our opinions into consideration.

if the wheel is off that's normal. The lugnuts are the only thing pressing the rotor against the hub.

does it do the noise when going forward after you have just backed up? if it does it could be the brakes were not seated properly in the caliper, or the retainers may not have been put back on.
