Braking Help

It might be the angle of the photo, but, it looks like the ears on those inner pads aren't straight. I'd put the inner pads on the caliper bracket without the caliper, and make sure the pads will slide in and out freely. Same thing with the calipers, slide those back and forth without the pads to make sure they have free movement and full range. The caliper shouldn't pinch those inner pads either. The outer ones should be a slight pinch fit however. You can bend the ears on the other pads to keep the pad from moving and rattling in the caliper.
