Front brake pad alignment?

[dieselandmud]

I have a 10 bolt front axle with 8-lug conversion on a 86' K-10. All the hardware is new except for the calipers. The brakes are making a loud squealing noise when I apply the brakes. I pulled them off and found this ridge on the piston side brake pad, both left and right sides are like this. I believe this is my noise maker. How do I align the pads on the calipers?
Thanks
Chris

Does your caliper mounting bolts still have those little sleeve bushing things in there? Looks to me like the piston is pushing in more on the top side.

Yes I installed new bushings on the caliper. The bolts did look a bit worn, I think I will change them out too.

When you get new bolts, check to make sure eventhing is tight and not any slop. If you can, have someone push the brake pedal while you watch the calipers.

I have great results with even application by putting some real slippery high temp grease on the sliding part of the bolt/pin . I use Sil-Glide .

I didn't grease the bolts/pins last time so that could be part of the problem. Thanks for all the help. Chris
