Dare I hesitate to say, greasing the tabs (that ride in the groove), might be your issue. Also, you DO have the little stamped steel insert in that fits into that groove, installed too? Yea, you want the pads to float in that groove, but too loose can cause them to squeel too. Why? To much up/down movement. What's loose to you and me, is super loose to a hydraulic system, meant to clamp down with force to bring a nearly 4,000 pound car to a stop. You do need to have some drag from the pads as they're in that groove. Grease there or too loose will cause this issue.

The only place any grease should be, is on your caliper pin bolt that allows the whole caliper to float back and forth. But that's sealed.

Could've been the material too. Might have gotten a mislabelled set.
