Well, pad shape and natual frequency is supposed to handle that. But if you're stuck with squealing pads.. well tape lasts a little longer than grease on the abutment clip (NEVER get it on the friction surface!)
The tape goes between the abutment clip and the support. (Bracket) Put a small dab of grease on the pad backplate ends.
In this picture it is the very top surface.
I found this pic on a quick google search. The grease apply to the back of the pad is usually a waste of grease but on rare occasion it helps. When this back of the pad apply helps, the tolerances of the caliper machining are too loose.

I've been doing it wrong.
I've used grease on the back of the pad between it and the caliper or it and the piston.
And usually the grease I get on the friction surface comes from the torn CV joint boot.
Thanks again.
So how, exactly, does God know that She's NOT a brain in a vat?
