5000CS TQ Rear brake pad shims?

[Louis A. Mulieri]

Hi,
 I ordered a new set of rear brake pads (ATE) for my 88 5KCSTQ. They
came without the thin metal/coating plates that my calipers currently have
between pistons and backs of pads. Are these plates shims or are they
there for heat/vibration control? The present ones are deteriorated and
I'd like to know whether they are necessary with ATE pads and what to call
them when ordering a new set.
	Also, if I don't put in new thin plates, do I need any anti-squeal
lubricant and where does it go?

Thanks

Lou
