The brake pad hardware that the pad sits in was touching the rotor and it sounded just like a wear sensor, light squeak. The rotor was also lightly touching the caliper mounting bracket. It was worse on the passenger side than the driver side, just a light touch. I was thinking that an easy way to do that is to put another rotor dust shield on between the hub bearing and the knuckle. The shield is .060"thick and I will trim off the bracket were it is bigger than the hub. I checked the GM parts book and the shields are $7.30 each. The brake hardware is stainless and was rubbing a groove into my rotor. Modifying the 2nd set of brake shields seems to be the easiest way I can think of to space the rotor out .060". I am going to call my buddy at the dealer Monday and have him find me some shields.
