Jimm 12/10/2012Usually, any rattling or excess nosie is due to wear or parts missing. You'll need to remove the wheels to inspect the brakes for any missing / broken / faulty brake hardware.
Try the many on-line auto parts sources, such as; www.autopartswarehouse.com or www.rockauto.com for the replacement parts, such as the brake hardware and hardware kits / caliper mounting pins.
