Id make sure you have the pads installed correctly. The one with the double jump goes on the inside.

Next make sure all metal on metal contact areas are lubed. Back of the pads where the pistons hit the pad and all the sliding interfaces between the caliper and pad. Have you replaced your rotors as well? If you only had them turned you may want to invest is some new ones.
I bought the powerstop set from stage3motorsports and am very happy with it.
I just had them turned , might have to look into new if i keep it much longer. Thanks
