You might try removing the pads wiping off the old grease from the sides of the metal on the pads then re-greasing them, or try not greasing them at all.
I think it may be the grease picking up dirt and making contact with the caliper that is causing the noise.

I don't quite understand. A member above posted a nice explanation of how and why your pads must be bedded. They must be bedded whether they squeal or not. There are plenty of explanations on the Internet of how to properly bed your pads.
But people act like any mention of bedding is conducted in a foreign language and couldn't possibly apply to them.
It takes 20 minutes and your brakes won't squeal and will operate better and will last longer. Yes, ceramic pads reduce dust, sometimes tremendously, but even they need to be bedded and even they sometimes squeal before bedding.
New car manufacturers like Chevrolet don't bed pads. You the owner have to bed your pads. You have to bed your new pads after every new installation.
Just think of squealing in your brakes as a reminder system. Everytime they squeal they are saying "bed me baby!"
Again, there is nothing wrong with a new Corvette with squealing brakes except that the car is being driven by an owner that doesn't know how to properly break in a new car brake system.
Said another way, you break in a new engine by driving it somewhat gently and smoothly at first. You break in new brakes by driving them very aggressively at first.

Bedding is especially important with a high performance car and the pad compounds used. The rotors need to have that layer of pad material embedded and it can't be done at the factory. In fact I think breaking in the brakes per the recommendations of being easy for the first ~500 miles is probably best but then bed them. When switching to Carbotech 1521's my rotors were broken in. I used a couple of 80 grit sanding pads and removed some old pad material from my rotors. Didn't really sand them but spent ~5 minutes on each rotor. I bedded them an my first drive. The Carbotech website gives the specs for bedding 1521's which is a bit different than their racing pads.
