Seized Guide pins - was... "pads/disks for 90"

[David Conner]

Clearly there is more than one type of lube... usually the stuff supplied
with the kit is clear or at least translucent.  I bought a tube of brake
caliper paste at NAPA and it's black.  I recently found a small packet in
the box with caliper seals and it looked different (silver/grey)...  I used
it on the guide pins.  Afterward I realized it was antiseize.  Maybe I'll
leave it on for a year as an experiment to see how it holds up.  I'm not
sure about Phil's remark that the reason it won't work is due to the
heat...  because I've heard that antiseize is used on furnace bolts.  But
maybe that's a different type of antiseize.
