Lubricating rear brake cylinder handbrake lever

Hi gurus
I am fitting new rear cylinders. My instinct tells me to lubricate the handbrake actuator piston, but what is the lubricant of choice? Red rubber grease or white calcium grease?

Personally I only ever use Red Rubber Grease on brake/hyd components.
I find sticking to one only saves potential for error and confusion.

The brake backplate should also be treated with Girling Green grease where the wheel cylinder slides.

Thanks for that.
My Rileys and the Javelin have sliding rear expanders, so I used the white calcium grease on the Minor backplates as it doesn't melt when hot, so doesn't migrate to where it shouldn't. I have put some on the handbrake lever pivot too.
Acting on previous advice I have lubricated everything inside the cylinder bore with red rubber grease.
Next job will be the handbrake cables. LM for them I guess.
I do allow myself a naughty light smear of copper grease on the threads of bleed nipples.
