Caliper slide pin questions

[ZZman]

I have brake parts coming for my 2002 Regal. I have done brakes before but have a few questions..

1. Why do one of the pins have a rubber end?
2. How do you know where these pins go?
3. Do you put just a little grease on the pins or a lot?

1)for noise and vibration(reduction)
2)where they came from.
3)that is kinda unscientific but somewhere in between. a little bit more than lightly but not blobs.
also never use those little packets they usually swell the rubber on the caliper guide pin.
use sil-glyde

Sil Glyde here as well and I apply it thick. I got mine at NAPA.

It seems as though the pin with the rubber end is always in the bottom position, at least on our cars (multiple Japanese models) as well as a '14 Fusion. Just checked the field service manual for my '08 Infiniti G35 and the brake component diagram doesn't refer to the rubber-ended pin but the picture shows an different pin on the bottom.

I don't skimp on SlyGlide.

How much grease is not as critical as choosing a compatible type.

Why do some pistons simply push in to make room for new pads and others need to be screwed backwards?

The screw backwards pistons are on rear breaks. This will keep the emergency brake adjusted
