Next time I check my pins I'm going to clean them up and spray them with silicone lubricant. It works great on all rubber parts and has no viscosity at all or temperature sensitivity.

This is making me go look at my Kawasaki manual for my bike... I am betting that those are installed dry as well.

Let us know ... aerosol silicone I am speculating will have no longevity in this setting. Would be great to get monitoring info. :D

I saved the OEM pins when I replaced them and I used ATE brake grease that I think I
found on sale at FCP one time. I've had so many freeze up over the years that I try to
use the correct type and I don't put too much on, just enough.
I thought the pins on the rebuilds just didn't look right - cheap.

Checked the manual, they don't go in dry but I have to say I never lube them as long as they're in good condition. On the car they rust real quick. I think @Abscate and I two months ago had them out. When I was doing my spring seat the other day it didn't exactly look great. Might be time to spend the $$$ on the good OEM caliper pins.

I tried spraying pins with silicone spray, don't think that's going to work. It has its place, probably not on the pins :\

Agreed with PeteB's suggestion above. I've been using that ATE brake grease for about 8 years on the pins and backs of the pads and it has worked well in my situation (relatively rust free North Carolina weather).
1997 855 GLT (Light Pressure Turbo) still going strong. Previous: 1986 240 GL rusted out in '06, 1985 Saab 900T rusted out in '95, 1975 Saab 99 rusted out in '95, 1973 Saab 99 rusted out in '94
