Nissan Repair: Clacking noise., brake noise, side tire

Question
Hi Von, I have a sentra SE-R 03 and when i'm driving over a crack / bump / unleveled surface I hear a clacking noise coming from the driver side tire (Or it sounds like that) I drive over the same area but applying my brakes slightly and I hear no clacking noises. Would you know what this might be?

Answer
Phil,

If breaking eliminates the noise I would say the pads are loose.  For about $20 bucks you can purchase a Nissan shim kit for the front brakes.  The plus side is the pads last longer and it eliminates brake noise.  courtesynissan.com is a good source if you can wait otherwise it is a dealer item and that would be about $10 bucks more unless you get your parts at the jobber rate.
