Rear PBR caliper rebuild help
So doing a rebuild on the rear calipers, the GM rebuild kit is no longer available, so i’m using the Carlson rebuilt kit. Problem is that the factory manual calls out for an unnamed “Liquid Lubricant” that is included in the kit to be on use on the parking brake actuator. Dose anyone know what this lubricant is?
Thanks
Thanks

Doing research over the weekend Iv found Castrol red rubber grease http://www.redrubbergrease.com it’s what the Porsche and BMW guys use for rubber on metal appliances in a braking system. I’m going to us it in the circle area in the picture.

As far as I can tell GM didn't put any grease in that location from the factory. When I rebuilt mine, I just left them dry
