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

[Fred Munro]

I found the lube supplied with the OEM guide pin boot kit wouldn't last a
year - the pins were rusty and the lube watery when I pulled them for the
yearly R&R. I switched to Superlube synthetic grease and it is working much
better - the pins don't rust and don't seize up.
The local Audi tech uses Quaker State synthetic grease as a guide pin lube.
