Hey guys,
What do you all use to lubricate your brake caliper slide pins?
I rebuilt a set of calipers about 18 months ago and used some Bendix Ceramic Synthetic Lube,

I didn't put these into service right away and have just inspected them prior to install. This stuff seems to have started becoming more of a solid. When I rubbed my finger over the lube is seemed to return to a thicker version of its former self. Maybe it'll be fine in service? I've done a lot of research online and it seems Toyota brake rubbers are more susceptible to swelling if the incorrect gear is used. Compounding this concern is the amount of conflicting advice given about brake lubes in general.
I have some Castrol Red Rubber Grease which is awesome for the hydraulic side of the system but I feel the temp range is far too low to be used on slides.
Maybe I'm just over thinking the situation

but any experience you could share, or anything to put my mind at ease would be appreciated.
