Re: Re: Rear Brake Options - '83 Ur-Q (slide pins)

Data point: in my efforts to keep caliper slide pins nice and moveable, I tried
the wheel bearing grease route a couple years ago - didn't seem to work. (Was on
a non-Audi, but no difference.) What I found a year later was as mentioned below,
the grease had become extremely thick and gummy, the only way to move/spread the
calipers was with the help/leverage of a pair of vice grips. Since then I have
taken to, whenever I have a wheel off, spraying a bit of lubricant under the
boots. Not sure if that's working or not. If someone does come up with the
perfect lube for these, I'd like to hear.
