Tell me about 'anti-rattle clips' for front brakes

I've had a rattle in the front brakes for quite a while - rattle when hitting bump without brakes applied, no rattle when brakes are applied.... I did a search and found mention of anti-rattle clips. What are they, where do they go, etc....??

Thanks, Dan D

Recently did a front disk brake job on my '96.
I posted pictures of the various parts...and locations..
I do not know if they are a factor on your noise or not....
