hey there so... ive gotta 96 gt and when i drive and i hit a lil bump in the road i can hear a lil noise coming from my wheels, which i believe has something to do with my brakes because when i tap the brakes the noise stops. ive had this problem for a while now and nobody can tell me why. I was told my brakes could be missing the thingy that hold the brake pad in place. any of y'all ever heard of this?
any help or info is greatly appreciated
