Permatex purple brake lube

My understanding of these 3200f claims is that the regular grease oil/thickener components of these super greases is still only good to the general 400 -600F range and that the ceramic/moly/teflon/whatever "marbles" components are what are left over and still present at very high temperatures. To me, it seems like dubious marketing.

I'm with dfarr67 - the old standby real silicone grease works well for enclosed pins. High moly paste for exposed to weather areas.
agreed. I can’t say that I’ve seen high solids lubes really keep a slick surface other than when fine moly is used like the Honda M-77. Mercedes often uses copper antiseize. While it works, it doesn’t seem particularly lubricating.

Silicone straight, or where necessary, with solids, seems the best bet. That’s why I just use M-77 and silicone.
 
I have often wondered how hot caliper pins actually got during operation and whether they really needed a high temperature grease. The technical datasheet for Molykote G-3407, a grease specifically made for caliper guide pins, seems to suggest otherwise as it only has a service range of -40C to 200C:

Interestingly, this grease seems quite similar to Toyota's "lithium soap based glycol grease" (Toyota Red Rubber Grease), and according to Dow Corning's marketing literature, G-3407 is the bee's knees when it comes to preventing fretting corrosion:
