The service manual for my 2002 Aurora tells me to use NIGLUBE on the brake
caliper slide pins. My Googling has not turned up a US source for this
stuff that is made by Nippon Grease Co, and I can't decipher the Japanese
hieroglyphics on their Web site. GM has a part number for it, but my guess
is that they will ask a premium price for a small quantity. What do you
folks who do GM brakes for a living use for this application?
