Lubricate Loaded Calipers? Brakes dragging intermittently

Ok, so now I've been able to go for a few drives with the new power disc conversion in and new wheels and it turns out that my brakes are randomly dragging. It's typically once I'm stopped at a long light, then I go to hit the gas and can tell the brakes are locked up. Then I stomp the brake pedal until it releases and then the car takes off. It's causing my engine to overheat though.. After googling the issue I found that the caliper pins should be greased....yet I have loaded calipers so there are no pins to grease. Does anyone know whether I should grease any portion of the brake pad hardware? I checked youtube and google and can't find any reference on lubricating loaded calipers. After inspecting one of them it does seem there is no play whatsoever on the brake pads and the piston is actually forming an impression on the back of the brake pad sitting against it. Seems like some light grease could potentially solve the issue. I already searched the brake threads in the forum and found nothing. Any thoughts?
