Dave, you might try some Permatex Ceramic Extreme Brake Part Lubricant like I did.
I lubed the pins, the contact surface of the pad to the piston and all the points where the pads slide on the caliper frame. Seems to have made a little difference.
I am using Red Stuff pads.
As a side note, I just replaced the front rotors, calipers and pads on my old Ford Probe with all NEW, not refurb parts for a sum total of $32 SHIPPED from Rock Auto. Go figure.
