Dude, I also have Carquest pads on my SC4 and i H A T E them. Worst pads ever. They squeal like I've never heard before. When I did my brake job, I regreased the sliders, used anti squeal grease on the back of the pads, used the shim kit and put anti-squeal grease on the back of the shims. Last, but not least, I even put anti squeal grease whereever the pads contacted the calipers. It's the pads, they just suck !Removed!.
